    Date & Time: Friday 14 January 2022, 17:00
    Speaker: Moshe Y. Vardi (Rice University, Texas)
    Title: From Greek Paradoxes to Political Paradoxes
    Location: Virtual

    On 14 January 2021, we celebrate World Logic Day. In the city of Kurt Gödel, Ludwig Wittgenstein, and the Vienna Circle, mathematical logic and its application to the sciences have a long and rich tradition. This January we celebrate Annual Vienna World Logic Day Lecture with Moshe Y. Vardi.

    The ancient Greeks invented logic, as a tool to discover eternal truths. They also invented paradoxes, as a tool to sharpen the mind. In his Vienna World Logic Day Lecture Moshe Vardi not only addresses Greek paradoxes but also talks about the adverse consequences of technology in our modern day society.

  • 11 January 2022, Computational Linguistics Seminar, Arthur Bražinskas

    Date & Time: Tuesday 11 January 2022, 16:00
    Speaker: Arthur Bražinskas (University of Edinburgh)
    Title: Abstractive opinion summarization
    Location: Zoom

    Opinion summarization is the automatic creation of text reflecting subjective information expressed in multiple documents, such as user reviews of a product. These short summaries can help users make better purchasing decisions by condensing useful information in hundreds or even thousands of reviews. However, due to the high cost of summary production, datasets large enough for supervised learning were absent until recently. This lead to a variety of extractive methods that construct summaries from review sentences. However, these methods often produce incoherent summaries with unimportant details. This presentation will focus on abstractive approaches that generate summaries using a free vocabulary and thus can yield more coherent texts. We will discuss summarizers trained in unsupervised, few-shot, and supervised regimes. These models combine principles of latent probabilistic models, variational inference, and reinforcement learning. In our unsupervised model (Copycat), we treat the product and review representations as latent continuous variables. At test time, we induce summarizing representations and map them to summarizing texts. In the supervised model (SelSum), we decompose the system into a selector (posterior) and summarizer. The selector treats reviews as latent categorical variables and selects a summary-relevant subset in training. Only the small subset is passed to the summarizer, which results in computational and memory savings. The system is trained end-to-end using variational inference and reinforcement learning. Finally, we fit another selector (prior) that selects subsets of informative reviews to summarize in test time.

    Date & Time: Friday 10 December 2021, 17:00-19:00
    Speaker: Amity Aharoni and Rodrigo Almeida (ILLC)
    Title: Brouwer's Intuitionism: Philosophy, the Continuum, and boxing with your Feet
    Location: Room D1.111, Science Park 904, Amsterdam

    When mathematicians and logicians hear the term 'intuitionism' they often think about the law of excluded middle, weak proof systems, and Heyting's formalisation of his teacher's philosophy. In this talk we will look at Brouwer's philosophy and mathematics of intuitionism, tracing some of the philosophical underpinnings, and motivating his mathematical results with contemporary mathematical tools. In it, we emphasise Brouwer's attempt to undermine the place of logic in the foundation of philosophy, replacing it with a special notion of 'intuition'.

    Speaker: Lucas Rosenblatt (Buenos Aires)
    Title: Theories of Paradoxicality
    Location: Online via Zoom

    A lot has been written on solutions to the semantic paradoxes but very little on the topic of general theories of paradoxicality. The reason for this, I believe, is that in most cases it is not easy to disentangle a solution to the paradoxes from a specific conception of what those paradoxes consist in. In this talk I want to do things differently. I will first address the question of what one should expect from a theory of paradoxicality. Then I will present and critically evaluate a number of theories that have been offered in the literature. The main claim I want to make is that, in many respects, these theories needn’t be seen as competing with one another. This is joint work with Camila Gallovich.

    Speaker: Vasily Romanovskiy
    Title: Ramsey's Representation Theorem for degrees of belief
    Location: Room D1.116, Science Park 904, Amsterdam

    In his pioneering ‘Truth and Probability’ (1931), Frank Ramsey sets out an influential account of the nature, measurement, and norms of partial belief. The centrepiece of this work is a representation theorem that allows Ramsey to construct a unique probability function representing an agent’s subjective degrees of confidence. In many ways, this marks the birth of decision theory as a field and the birth of the subjective interpretation of probability. In this expository talk we will examine the philosophical background underlying Ramsey’s goals in this work, we will re-construct the main formal moves Ramsey makes in proving his representation theorem and finally, we will criticise some of the philosophically contentious assumptions that permeate throughout ‘Truth and Probability’ (1931). Taking a broader perspective, representation theorems are the underbelly of much work in theoretical economics, the underbelly behind claims like ‘humans are rational’. This talk will give a first-hand look at (just) one such representation theorem, but the illustrative purposes this will serve will hopefully be felt by anyone who is a slave of some defunct economist. Which, if some are to believed, includes all of us.

    Speaker: Tibo Rushbrooke
    Title: A Meaning-Relative Logical Consequence Relation
    Location: Room D1.111, Science Park 904, Amsterdam

    In his seminal 1936 paper "On the Concept of Logical Consequence", Tarski provides a notion of logical consequence which has become standard in analytic philosophy today. Tarski argues that logical consequence is independent of the meanings of non-logical terms, on the grounds that a logical inference cannot rely on any empirical knowledge of the objects referred to. Accordingly, he defines a logical consequence relation which is insensitive to the meanings of the non-logical vocabulary. In this talk, I will closely scrutinise Tarski’s original reasoning. I will then give an alternative notion of logical consequence in natural language, which is entirely sensitive to the meanings of the terms involved. I argue that the alternative notion is both interesting and fruitful, in that it captures certain inferences not reckoned as ‘logical’ by the traditional notion, thus broadening the scope of logic.

    The reading group is about the book: Peters, Janzing & Schölkopf (2017), Elements of Causal Inference: Foundations and Learning Algorithms, The MIT Press. The book "teaches readers how to use causal models: how to compute intervention distributions, how to infer causal models from observational and interventional data, and how causal ideas could be exploited for classical machine learning problems". It can be openly accessed from the publisher's website.

    For our first meeting, we have to read the first three chapters:
    1. Statistical and Causal Models (pp. 1-14)
    2. Assumptions for Causal Inference (pp. 15-32)
    3. Cause-Effect Models (pp. 33-42).

    The reading group is held under the supervision of Dr. Katrin Schultz and is organized along with Evan Iatrou (MoL student, ).

    Title: Carroll’s Regress, Guidance and Explicit Representation
    Location: Online via Zoom

    Abstract: What is the nature of one’s justification to use a logical principle such as Modus Ponens in reasoning? It is widely agreed amongst epistemologists of logic that such justification cannot be internalist. One key reason offered for this view is that internalist accounts of justification are susceptible to Carroll-style regresses. In this talk, I examine this claim and argue that internalist accounts of justification are not open to such regresses. I further argue that the sorts of externalist accounts of the justification of logical principles typically put forward as alternatives are inadequate.

    Speaker: Ulle Endriss
    Title: Judgment Aggregation
    Location: AUC Common Room - Science Park 113, Amsterdam

    This lecture will be an introduction to the theory of judgment aggregation (JA). JA deals with the problem of combining the views of several individual agents regarding the truth of a number of propositions, expressed in the language of logic, into a single such view that appropriately reflects the stance of the group as a whole. Applications of JA range from aggregating the opinions of several judges in a court of law into a single legal opinion, all the way to aggregating information received from several autonomous software agents in the context of distributed computing systems.

  • 15 October 2021, Compositionality in the domain of tense, mood and aspect, Amsterdam (the Netherlands)

    Date & Time: Friday 15 October 2021, 13:30-17:00
    Location: Paushuize, Kromme Nieuwegracht 49, Utrecht, the Netherlands (in the centre of Utrecht, 100 meters away from the Academy Building)

    In October this year Cambridge University Press will publish The Compositional Nature of Tense, Mood and Aspect, written by Henk Verkuyl (UiLOTS, Utrecht). The title of this book clearly alludes to the PhD defended in Utrecht on Friday 15 October 1971, called On the Compositional Nature of the Aspects. It was published in 1972 without substantial corrections. The fact that October 15 this year will fall on a Friday was such a nice coincidence that it was impossible to escape from the idea that the book could be presented on that very day in a celebratory setting of some sort, exactly fifty years later. This has been developed into the more concrete idea of a workshop with distinguished speakers working in the domain of tense, aspect and mood who could connect their contribution to topics broached in the new book. The book addresses both linguists and logicians, so we are happy that UiLOTS (Utrecht) and ILLC (Amsterdam) have joined forces in organizing this workshop.

    Title: Ecumenical modal logic
    Location: Online

    Abstract: Recent works about ecumenical systems, where connectives from classical and intuitionistic logics can co-exist in peace, warmed the discussion of proof systems for combining logics, called Ecumenical systems by Prawitz and others.

    In Prawitz’ system, the classical logician and the intuitionistic logician would share the universal quantifier, conjunction, negation, and the constant for the absurd, but they would each have their own existential quantifier, disjunction, and implication, with different meanings.

    We extended this discussion to alethic K-modalities: using Simpson’s meta-logical characterization, necessity is shown to be independent of the viewer, while possibility can be either intuitionistic or classical.

    We furthermore proposed an internal and pure calculus for ecumenical modalities, where every basic object of the calculus can be read as a formula in the language of the ecumenical modal logic.

    Your career after a PhD or postdoc might not be a topic you often think about, but it is important! Most PhD students and postdocs will not end up working as a scientist at a university, but what are your options outside academia? These career lunches are organized to help orient yourself on possible career paths. During the event, two invited guests will share their career story and in moderated sessions they will answer your questions about what it is like to work as a PhD graduate in a non-academic environment.

    Title: Improving the Buurtbudget: Can mathematics and Computer Science help?
    Location: Room C0.05, Science Park 904, 1098 XH, Amsterdam

    The buurtbudget, known as participatory budgeting in English, is a democratic process aiming at involving citizens in public spending decisions. In several neighborhoods of Amsterdam, residents already can vote for community-driven projects to be paid for from public funds. However, organizing this process is not straightforward, especially when it comes to making a decision based on the ballots that have been submitted. During this talk, we will see why some natural procedures to determine the winning projects suffer major drawbacks and how to circumvent those drawbacks.

    Title: Graaf Tel en de drie-en-een-half miljard dollar vraag
    Location: Room C1.110, Science Park 904, 1098 XH, Amsterdam

    Tellen kunnen we bijna allemaal. Toen ik jong was leerde ik vleermuizen tellen met Graaf Tel. Nu ik wat ouder ben tel ik examens die ik moet nakijken. Maar wat is tellen eigenlijk? En is tellen wel zo kinderlijk eenvoudig als het lijkt? In dit praatje denken we na over de dingen die we tellen en hoe tellen zich verhoudt tot de concepten die we gebruiken. We zullen zien dat tellen met verschillende filosofische puzzels samenhangt en dat het zelfs een verschil van drie-en-een-half miljard dollar kan maken.

    Under the auspices of FoLLI the European Summer School in Logic, Language, and Information (ESSLLI) is organized every year in a different European country. It takes place over two weeks in the European Summer, hosts approximately 50 different courses at both the introductory and advanced levels, attracting around 400 participants each year from all the world.

    The main focus of the program of the summer schools is the interface between linguistics, logic and computation, with special emphasis in human linguistic and cognitive ability. Courses, both introductory and advanced, cover a wide variety of topics within the combined areas of interest: Logic and Computation, Computation and Language, and Language and Logic. Workshops are also organized, providing opportunities for in-depth discussion of issues at the forefront of research, as well as a series of invited lectures.

    The circumstances around the coronavirus (COVID-19) pandemic forced the organizers to postpone the 32nd edition of ESSLLI, planned for 2020 in Utrecht as ESSLLI-2020, to 26 july-13 august 2021, as well as hold it online. In view of the online format, the program is spread over three weeks so as to facilitate attendance.

     - What makes something sound sad?
     - And how is it that listening to sad music can be enjoyable?
    Enriched by an interdisciplinary panel discussion, and accompanied by a measured dose of sad music.

    Title: Introduction to quantum circuits
    Location: Zoom

    Any Boolean function can in principle be decomposed into elementary logical gates, such as AND, OR and NOT, that act only on one or two bits at a time. Similarly, any operation on a quantum computer can be broken up into elementary gates that act only on one or two qubits at a time. I will explain how this works and what consequences this has for quantum algorithm design.

    Title: Hyperintensional Evidence Logics for Knowledge and Belief
    Location: Room C1.10, Science Park 904, Amsterdam / Online via Zoom

    Traditional epistemic logic often comes without any notion of evidence and renders belief and knowledge susceptible to logical omniscience. I present an approach that defines belief and knowledge based on hyperintensional evidence, which comes with a notion of evidential aboutness and gives rise to more realistic epistemic agents.

    Title: Group (Ir)Rationality: Can Logic help?
    Location: Zoom

    Abstract: I present some applications of logical methods (in particular, of so-called dynamic epistemic logics) to the study of emergent phenomena in groups of `agents', capable of reflection, communication, reasoning, argumentation etc.The main focus on the understanding of belief/preference formation and diffusion in social networks, and on how this affects the group's ``epistemic potential": the ability of the agents to track the truth of the matter (with respect to some given relevant topic). While in some cases, ``wisdom of the crowds" can increase the epistemic potential, in other situations the group's dynamics leads to informational distortions (-- the ``madness of the crowds": cascades, ``groupthink", the curse of the committee, pluralistic ignorance, group polarization, doxastic cycles etc). I explain how logic (in combination with probabilistic methods) can be used to provide some explanations for both types of situations, as well as to suggest some partial solutions to informational distortions.

    Title: Through the looking glass-Information flows in complex systems
    Location: Zoom

    Understanding dynamical systems is a fundamental problem for the 21st century. Despite the prima facie differences and purposes of many real-world networks, previous research shows several universal characteristics in networks properties such as the small-world phenomenon, fat-tail degree and feedback loops. This has led to the common but often implicit assumption that the connectedness of a node in the network is proportional to its dynamic importance. For example in epidemic research, high degree nodes or "super-spreaders" are associated to dominant epidemic risk and therefore deserve special attention. Yet prior research shows that the shared universality in network characteristics is not shared in the dynamic or functional properties of many real-world systems.

    In this talk I will explore the relation between local interactions and macroscopic properties of a system through the lens of statistical physics and information theory. In particular, I will show novel methods on determining the so-called driver node in complex systems, and how tipping points can be studied from an information theoretical perspective.

    Title: Epistemic Logic without Possible Worlds
    Location: Room C1.10, Science Park 904, Amsterdam / Online via Zoom

    Abstract:

    While possible worlds can be seen as the semantic backbone of epistemic logic, they can be tedious to deal with. In this talk I introduce epistemic presentations, a kind of structure wherein "issues on the table" are primitive objects and possible worlds are only derivative. In addition to be more flexible, these models lend themselves to an interesting algebraic approach and provide inspiration for new dynamic operators.

    Location:

    We have a room in the big building of Science Park (house 904, room SPC1.110) with corona capacity 44. The talk will also be streamed live on Zoom. For the Zoom address, please email .

  • 7 - 9 June 2021, Logic of Conceivability Conference 2021, Online

    Date: 7 - 9 June 2021
    Location: Online

    The ability to think about non-actual possibilities is crucial for rational decision and action. When deciding what to do in situations of uncertainty or risk, we use our powers of imagination and conception to surveil the ways the world might be for all we know, and ponder the possible consequences of our actions. What is the logic of conceivability? Do thinking and imagining exhibit sufficient structure so to be amenable to precise modeling? Under what conditions does an imaginative episode establish a non-actual scenario as a real possibility? What are the special features of thought, talk and knowledge about mere possibility and conditionality? The aim of this conference is to facilitate the conversation on these questions by bringing together both senior and rising young researchers from around the world.

  • DIP Colloquium cancelled

    Title: An overview and characterization of generalized information measures
    Location: Online (Zoom)

    The aim of this talk is to present a comprehensive classification of the main entropic forms introduced in the last fifty years within statistical physics and information theory and to review the fundamental questions about the meaning of information. I will particularly focus on axiomatic approaches to the characterization of various generalizations of the Shannon entropy, such as the Rényi, the Tsallis, the Sharma-Mittal, and the Sharma-Mittal-Taneja entropies, as well as the more general classes of pseudo-additive entropies with a well-defined mathematical and information theoretic structure. Finally, I will point out possible applications of these measures in communication theory, statistical inference and complex systems modeling.

    Title: Deliberation, Coherent Aggregation, and Anchoring
    Location: Zoom

    In this talk we will present a number of results stemming from a computational model of collective attitude formation through a combination of group deliberation and aggregation. In this model the participants repeatedly exchange and update their preferences over small sets of alternatives, until they reach a stable preference profile. When they do so the collective attitude is computed by pairwise majority voting. The model shows, on the one hand, that rational preference change can fill an existing gap in known mechanisms purported to explain how deliberation can help avoiding incoherent group preferences. On the other hand, the model also reveals that when the participants are sufficiently biased towards their own opinion, deliberation can actually create incoherent group rankings, against the received view. The model suggests furthermore that rational deliberation can exhibit high levels of path dependencies or "anchoring", where the group opinion is strongly dependent on the order in which the participants contribute to the discussion. We will finish by discussing possible trade-offs between such positive and negative features of group deliberation.

    Date & Time: Thursday 22 April 2021, 19:00-20:30
    Location: Zoom

    [Dutch only]

    Artificiële intelligentie moet ons leven verrijken, maar er niet mee aan de haal gaan. Het moet zich houden aan door mensen gehanteerde logica en principes voor rationaliteit, moraliteit en consistentie. Kortom, wij willen machinaal handelen kunnen begrijpen en sturen. Mens en machine moeten elkaar in voldoende mate verstaan om op de gewenste manier met elkaar om te gaan.

    Vier sprekers (Catholijn Jonker, Jan Broersen, Rineke Verbrugge en Bart Jacobs) leggen uit welke rol logica, in combinatie met probabilistisch denken, speelt in het onderzoek naar de vervulling van deze wensen.

    Title: An Almost Constructive Proof of Brouwer's Fixed Point Theorem
    Location: Online via Zoom

    As a young mathematician, Brouwer gained prominence by proving a number of fundamental theorems in topology, the most famous of which is his eponymous fixed point theorem. However, Brouwer would later come to reject this theorem as not intutionistically acceptable. In this talk, I will (briefly) sketch the proof of Brouwer's fixed point theorem as it is given in most textbooks, and present an alternative, 'almost constructive' proof based on Sperner's lemma. I will also discuss how this second proof can be used to obtain intuitionistically valid variants of the fixed point theorem.

  • 29 - 30 March 2021, Workshop Lexical Restrictions on Grammatical Relations

    Date & Time: 29 - 30 March 2021, 09:00-16:30
    Location: Online via Zoom

    In many languages grammatical relations are to some extent lexically restricted, in the sense that certain verbs or verb classes take different argument coding frames than others. While such constraints are well studied for case marking, they have also been reported for grammatical relations defining other types of constructions, including a range of voice- and valency-related constructions and some clause-combining constructions. This hybrid (on-line/on-site) workshop aims to unite scholars from different (sub)disciplines, bringing together descriptive, comparative, corpus-based, and experimental studies, as well as studies that compare linguistic data with genetic and/or socio-historical evidence. Together, we hope to further our understanding why lexical restrictions should exist, how they are processed and acquired, and why/how/where they persist in languages.

    Title: The Origins of Language: Evidence from Nicaraguan Sign Language
    Location: Online, via Zoom

    All human societies have languages capable of expressing the richness of human thought. To what extent is this achievement an historical accomplishment, similar to mathematics or science, and to what extent does it rely on our evolved cognitive capacities? I study these questions by looking at language creation in different communities, including Nicaraguan Sign Language (a new language only 50 years old), homesign systems, and laboratory-created communication systems. I will present results on how a new language comes to have recursion and quantifiers like “some” and “all." In both cases, I find evidence for rapid emergence of linguistic structure within a few generations. One possible explanation for these findings is that features that emerge early are those that reflect underlying shared semantic structures that are universal (or nearly) in languages. In contrast, the features that emerge later (e.g., grammatical morphology) may be those that vary across languages and require convergence and iterated learning.

    This talk will be given in American Sign Language (ASL) and interpreted into English. If anyone would like to attend the talk and have it interpreted in Sign Language of the Netherlands (NGT), please send an email to in advance and we will do our best to arrange an NGT interpreter.

    Title: Session Coalgebra: Using State-based Systems to Describe Communication Protocols
    Location: Online (Zoom)

    Type systems are a useful tool to prevent programmers from making obvious mistakes, but they are generally quite limited in what they can describe. We've taken a look at a session types, a type system aimed at describing communication protocols, and checking that programs adhere to these protocols. Where previous work on session types has treated them as syntactical objects, we find that protocols have a natural notion of state and characterize them as coalgebras, i.e., state-based machines. In doing so, we retrieve natural definitions for type-equivalence, subtyping and duality of types as coinductive relations between states. In my talk I'll explain what session types are and present our syntax-free description of protocols as states of a coalgebra (without assuming prior knowledge of coalgebras).

    Speaker: Balder ten Cate (Google Research)
    Location: Online via Zoom

    Over the last decade, advances in machine learning have taken the computer science community by storm, enabling new applications and pushing the envelope on existing ones. Even on tasks that are traditionally viewed as falling in the domain of logical reasoning (e.g., reading comprehension tasks), deep neural models are now the state-of-the-art. Furthermore, logic and learning are perceived by some as being distinct or even opposing approaches. At the same time, while various algorithmic and hardware limitations that inhibited deep learning solutions in the past have been successfully addressed, other fundamental problems arise, such as problems concerning fairness, explainability, and controllability. In this talk, I will discuss a few problems at the intersection of machine learning and logic, including providing deep models with means to access structured knowledge.

    Title: Judgements of Social Groups
    Location: Zoom (contact Katrin for the link)

    Abstract:
    A stereotype is a generalization about a class of people but does not necessarily represent every individual with the group (McCauley, Stitt, & Segal, 1980). Category information (i.e., stereotype information) is often used to make probabilistic predictions about people within a particular group. For instance, a probabilistic judgement about Germans would be that, “Germans are more likely than other people to be efficient.” Here we are making a prediction about an individual’s personality (i.e., efficiency) based on their group membership (i.e., German). McCauley and Stitt (1978) suggest that people are accurately Bayesian in their judgements and tend to make probabilistic judgements about people’s personality based on stereotype information. The current project aims to replicate the original McCauley and Stitt (1978) work to test whether stereotype prediction from category information to personality adheres to Bayes’ rule.

    Title: Luca Incurvati's 'Conceptions of Set and the Foundations of Mathematics'
    Location: Online via Zoom

    Our Philosophy of Mathematics Reading Group has the honor to start 2021 by hosting Luca Incruvati presenting his 2020 book 'Conceptions of Set and the Foundations of Mathematics' published by the Cambridge University Press. The book is accessible from the UvA Library.

    Book Summary: Sets are central to mathematics and its foundations, but what are they? In this book Luca Incurvati provides a detailed examination of all the major conceptions of set and discusses their virtues and shortcomings, as well as introducing the fundamentals of the alternative set theories with which these conceptions are associated. He shows that the conceptual landscape includes not only the naïve and iterative conceptions but also the limitation of size conception, the definite conception, the stratified conception and the graph conception. In addition, he presents a novel, minimalist account of the iterative conception which does not require the existence of a relation of metaphysical dependence between a set and its members. His book will be of interest to researchers and advanced students in logic and the philosophy of mathematics.

    Title: "From Aristotle to the iPhone" (WLD 2021 event)
    Location: Virtual

    Abstract: Logic started as a branch of philosophy, going back to Greeks, who loved debates, in the classical period. Computers are relatively young, dating back to World War II, in the middle of the 20th century. This talk tells the story of how logic begat computing, tracing the surprising path from Aristotle to the iPhone. This is a story full of both intellectual drama, as well as real-life drama, with most of the characters dying young, miserable, or both.

    The talk is part of a series of World Logic Day events and is aimed at a general audience.

    Location: Pasadena CA (U.S.A.) or virtual
    Deadline: Friday 3 December 2021

    The widespread use and increasing complexity of mission-critical and safety-critical systems at NASA and in the aerospace industry requires advanced techniques that address these systems' specification, design, verification, validation, and certification requirements. The NASA Formal Methods Symposium (NFM) is a forum to foster collaboration between theoreticians and practitioners from NASA, academia, and industry. NFM's goals are to identify challenges and to provide solutions for achieving assurance for such critical systems. The focus of the symposium will be on formal/rigorous techniques for software assurance, including their theory, current capabilities and limitations, as well as their potential application to aerospace during all stages of the software life-cycle.

    The NASA Formal Methods Symposium is an annual event organized by the NASA Formal Methods (NFM) Research Group, composed of researchers spanning six NASA centers. The organization of NFM 2022 is being led by the Jet Propulsion Laboratory (JPL), located in Pasadena, California. The symposium is planned to be held in person at California Institute of Technology, but potentially transitioning to fully virtual if the COVID situation persists. Virtual presentations will be possible even if the conference is held in-person.

    There are two categories of submissions: Regular papers describing fully developed work and complete results (maximum 15 pages, excluding references) and Short papers on tools, experience reports, or work in progress with preliminary results (maximum 6 pages, excluding references). Additional appendices can be submitted as supplementary material for reviewing purposes. They will not be included in the proceedings. All papers must be in English and describe original work that has not been published.

    Authors are encouraged, but not strictly required, to submit artifacts that support the conclusions of their work (if allowed by their institutions). Artifacts may contain software, mechanized proofs, benchmarks, examples, case studies and data sets. Artifacts will be evaluated by the Program Committee together with the paper.

    Courageous authors, who want to delve in open source software being applied in real NASA missions, and find possible connections to and applications of Formal Methods, are invited to visit the open source repositories for the 'F' and 'cFS' frameworks for programming flight software.

    Costs: See Unilog web site
    Deadline: Saturday 9 October 2021

    Hybrid logic is a branch of modal logic in which it is possible to directly refer to worlds/times/states or whatever the elements of the (Kripke) model are meant to represent.

    Hybrid logic is now a mature field with significant impact on a range of other fields, including
    - applied modal logics,
    - temporal logic,
    - labelled deduction,
    - philosophy of time, and
    - social reasoning.

    The scope of the workshop is not only standard hybrid-logical machinery like nominals, satisfaction operators, and the downarrow binder, but generally extensions of modal logic that increase its expressive power.

    The duration of the workshop is a half day or one day and it will take place at some point during the UNILOG congress, April 6-11, 2022.

    We welcome contributions to the the theory and applications of hybrid logic. To submit a contribution, send a one-page abstract to both organizers of the workshop. Please write "HyLo submission" in the subject field. Depending on the quality of the abstracts, there might be a follow-up special issue of a journal, with a separate refereeing round.

  • 17 - 18 March 2022, Bilateralism and Proof-Theoretic Semantics, Ruhr University Bochum

    Date: 17 - 18 March 2022
    Location: Ruhr University Bochum
    Target audience: PhD students and early Post-Docs
    Deadline: Sunday 28 November 2021

    The topic of bilateralism - situated in the area of proof-theoretic semantics - has received considerable attention in the area of philosophical logic within the past years. According to proof-theoretic semantics the meaning of the logical connectives is determined by the rules of inference governing their use in proofs. In this context bilateralism demands an equal consideration of dual concepts like truth and falsity, assertion and denial, or proof and refutation in that they should both be taken as primitive concepts, i.e. not reducible to each other. This conference aims at sharing and discussing the latest research in this area by bringing together both highly distinguished as well as early career researchers.

    Invited Speakers: Nils Kürbis (University of Łódź & Ruhr University Bochum), Greg Restall (University of St. Andrews), David Ripley (Monash University), Luca Tranchini (University of Tübingen), Peter Verdée (UCLouvain) and Heinrich Wansing (Ruhr University Bochum).

    Next to the presentations of the invited speakers the conference is supposed to give a number of early career researchers the opportunity to present their work in this area. Session times will be 40 min., divided into 30 min. for the presentation followed by 10 min. of discussion.

    Therefore, PhD students and early Post-Docs are invited to submit an extended abstract on their research. To submit, send an anonymized abstract of 800-1000 words (excluding references) to .
    Members of groups that are underrepresented in logic are especially encouraged to submit.

    The deadline for abstract submission is November 28, 2021.
    The notification of acceptance will be sent by January 16, 2022.
    A special issue of Bulletin of the Section of Logic on the topic of the conference is planned in which full versions of selected papers will be published after an open call for papers.

    Due to the current situation concerning COVID-19 and very uncertain predictions about what will happen in the autumn, after several consultations the organizers of the conference decided to postpone it until the year 2022. We want the event to keep its on-site character, which, however, requires that the pandemic is overcome. The conference date has been changed to 14-18.03.2022 and hopefully it will not have to be subject to further revision.

    Participants are requested to submit their papers on all topics relevant to the conference. Topics of either theoretical or applied interest include, but are not limited to: many-valued logics, modal logics, non-monotonic logics, paraconsistent logics, plausible reasoning, substructural logics, contra-classical logics, relevant and connexive logics, and/or description logics. Contributions from other related areas such as: cognitive science, computer science, foundations of mathematics, philosophy of language, and/or philosophy of mind, are also welcome. Cross-cutting contributions are particularly welcome.

    Articles should be in English, written in the EPTCS format. . They must not exceed 12 pages excluding references and clearly marked appendices.

  • 4 - 6 February 2022, ICAART Special Session on "Natural Language Processing in Artificial Intelligence" (NLPinAI 2022), Online

    Date & Time: 4 - 6 February 2022, 23:59
    Location: Online
    Deadline: Friday 26 November 2021

    Computational and technological developments that incorporate natural language are proliferating. Adequate coverage encounters difficult problems related to partiality, underspecification, and context-dependency, which are signature features of information in nature and natural languages. Furthermore, agents (humans or computational systems) are information conveyors, interpreters, or participate as components of informational content. Generally, language processing depends on agents' knowledge, reasoning, perspectives, and interactions.

    The session covers theoretical work, applications, approaches, and techniques for computational models of information and its presentation by language (artificial, human, or natural in other ways). The goal is to promote computational systems of intelligent natural language processing and related models of thought, mental states, reasoning, and other cognitive processes.

    Prospective authors are invited to submit papers in any of the conference topics. Guidelines and instructions for preparing the manuscript (in Word and Latex formats) are available at the confernce website. Papers must be submitted electronically via the web-based submission system.

    All accepted papers will be published in a special section of the conference proceedings book - under an ISBN reference and on digital support and be made available at the SCITEPRESS Digital Library. We expect a Special Issue with extended publications based on selected papers presented at NLPinAI 2022 at ICAART 2022.

  • 20 - 21 January 2022, The Sixth Image Schema Day Workshop, Joenkoeping, Sweden

    Date: 20 - 21 January 2022
    Location: Joenkoeping, Sweden
    Deadline: Friday 10 December 2021

    In broad terms, image schemas are spatiotemporal relationships between objects and agents that are learned in early infancy such as containment, support and linkage. These relationships are hypothesised to construct the information skeleton found in object affordances, linguistic and artistic metaphors, the conceptualisation of event segmentation and analogical reasoning. Traditionally studied in cognitive linguistics, these abstract patterns gained increased interest to solve some of the semantic grounding issues in AI and cognitive robotics, but are also a familiar sight in interaction design, art and literary analysis, developmental psychology, and gesture interpretation, to name but a few.

    To offer a platform to discuss this topic across the disciplines, the workshop The Image Schema Day was born in 2015, and so far, it gathered researchers on five different occasions. The workshop is primarily a networking event that invites researchers on image schemas and related notions from a broad range of scientific disciplines to present their research and discuss ideas for future projects. After two years of hibernation, we are happy to announce that the Image Schema Day (ISD6) is returning in its sixth reincarnation: at a new venue, with new research, but with the same purpose. Unlike many other workshops focused on different topics in one discipline or using one methodology, the ISD6 invites researchers from all disciplines and methodologies but focuses on one topic.

    The workshop accepts three forms of submissions: Abstracts for presentation (2 pages), Extended abstracts (at least 5 pages) of either preliminary work and ideas or summaries of previously published articles, and Research papers (5-10 pages) discussing novel research not published (or under review) at another venue.

    Topics of interests with (the broadest of interpretation of) an image-schematic focus include, but are not limited to conceptual metaphors, affordances, spatiotemporal reasoning, force dynamics, conceptual modelling, embodied and spatial cognition, general artificial intelligence, commonsense reasoning, analogical reasoning, cognitive robotics, interface design, art and literature analysis.

  • 13 - 17 December 2021, Logic and Algorithms in Computational Linguistics 2021 (LACompLing2021), Montpellier, France and Online

    Date & Time: 13 - 17 December 2021, 08:00-21:00
    Location: Montpellier, France and Online
    Target audience: researchers, academic people
    Costs: 20 Euro
    Deadline: Sunday 14 November 2021

    Computational linguistics studies natural language in its various manifestations from a computational point of view, both on the theoretical level (modeling grammar modules dealing with natural language form and meaning, and the relation between these two) and on the practical level (developing applications for language and speech technology). Right from the start in the 1950s, there have been strong links with computer science, logic, and many areas of mathematics - one can think of Chomsky's contributions to the theory of formal languages and automata, or Lambek's logical modeling of natural language syntax. The symposium assesses the place of logic, mathematics, and computer science in present day computational linguistics. It intends to be a forum for presenting new results as well as work in progress.

    The symposium focuses mainly on logical approaches to computational processing of natural language, and on the applicability of methods and techniques from the study of artificial languages (programming/logic) in computational linguistics. We invite participation and submissions from other relevant approaches too, especially if they can inspire new work and approaches.

    LACompLing2021 is part of the week "Mathematical Linguistics (MALIN) 2021"

    We welcome submissions of abstracts of presentations of original work.

  • 8 - 10 December 2021, Workshop "Mathematics as/in Science", Gent, Belgium

    Date: 8 - 10 December 2021
    Location: Gent, Belgium
    Deadline: Monday 25 October 2021

    The relationship between mathematics and science continues to be of considerable philosophical interest. Within contemporary philosophy of science, for example, pinpointing the exact role of mathematics in the sciences remains a hotly debated issue. Does mathematics play a mere inferential role in that it allows for the derivations of one substantial truth from another or is mathematics more than a 'theoretical juice-extractor'? Are there distinctive mathematical explanations of physical phenomena? Similar questions can be asked about the role of logic in science.

    These issues connect with discussions within the philosophy of mathematics (and the philosophy of logic) concerning the nature of mathematics (or logic). Within the philosophy of mathematics, Platonists, nominalists and structuralists consider mathematics to be fundamentally different in kind from empirical science, while empiricists have argued that mathematics is, just like other sciences, fundamentally about aspects of the empirical world. Different positions within the debate about the nature of mathematics will, arguably, lead to different answers to the question as to how mathematics and science are related.

    In this workshop we want to focus on how these different philosophies of mathematics fare in giving an account of mathematical practice and the role of mathematics in scientific practice.

    We welcome contributions that approach these (and related) topics either from a systematic or a historic angle. In other words, we welcome contributions that elaborate and defend your own position, but also contributions that discuss the views that philosophers and scientists had on these topics in the past.

  • 6 - 8 December 2021, Trends in Logic XXI "Frontiers of connexive logic", Bochum, Germany

    Date: 6 - 8 December 2021
    Location: Bochum, Germany
    Deadline: Tuesday 14 September 2021

    The 21st Trends in Logic international conference will be held at Ruhr University Bochum, Germany, from December 6-December 8, 2021 under the title 'Frontiers of connexive logic'. It is organized by the chairs of Logic and Epistemology and Nonclassical Logic at the Department of Philosophy I of Ruhr University Bochum, in co-operation with Studia Logica.

    Modern connexive logic started in the 1960s with seminal papers by Richard B. Angell and Storrs McCall. Systems of connexive logic have been motivated by considerations on a content connection between the antecedent and succedent of valid implications and by applications that range from Aristotle's syllogistic to Categorial Grammar and the study of causal implications. As we are observing some growing interests in topics related to connexive logics, after six annual workshops, the Trends in Logic XXI aims at discussing directions for future research in connexive logics.

    Any papers related to connexive logics are welcome. Moreover, we will have a special session on contra-classical logics, and thus any papers related to contra-classical logics are welcome. Submissions of extended abstracts (up to three pages) should be submitted electronically as pdf documents using the EasyChair submission page. At least one author of each accepted paper must register for, and attend, the conference to present their work. Full versions of selected papers will be published in a special issue of Studia Logica after an open call for papers.

  • CfP special issue of Topoi on "Mathematical Practice & Social Ontology"

    Deadline: Wednesday 1 December 2021

    The relationship between mathematics and social ontology is often guided by the question of the possibility of applying mathematics to social sciences, especially economy. As interesting as these questions may be, they neglect the inverse possibility of applying a conceptual analysis derived from social ontology to mathematics. The issue will be devoted to the question whether the distinction between social object and social fact, on the one hand, and between different theoretical approaches to the notion of social fact, can be successfully applied to mathematical practice.

    All papers will be double-blind peer-reviewed. Submission is organized through TOPOI's online editorial manager. Papers should not exceed 8000 words (excluding notes).

  • 23 - 26 November 2021, 3rd international conference on Non-classical Modal and Predicate Logics (NCMPL 2021), Bochum, Germany (Hybrid)

    Date: 23 - 26 November 2021
    Location: Bochum, Germany (Hybrid)
    Deadline: Wednesday 15 September 2021

    Modalities and predicates have since ancient time been central notions of logic. In the 20th century, various systems of non-classical logics have emerged, with applications in many disciplines like Computer Science, Linguistics, Mathematics, and Philosophy. This gave rise to the questions of a non-classical treatment of quantifiers and modalities and the accommodation of quantifiers and modalities in non-classical logics. In response, various modal and predicate variants of non-classical logics have been introduced and studied in the past decades.

    NCMPL is a conference series solely dedicated to modal and predicate non-classical logics. The aim of the conference is to bring together researchers from various branches of non-classical logics, not only to present recent advances in their particular fields, but also to identify common problems and methods and foster the exchange of ideas between researchers from separate fields.

    Papers are sollicited. The scope includes theoretical works on the conference topics coming from all branches of formal logic (proof-theory, model theory, game theory, computational complexity, philosophical and historical aspects), as well as their applications in computer science, linguistics, philosophy, etc. Strong papers on propositional logics can also be accepted, provided they relate to the themes in the main scope of the conference (e.g., the study of completions in algebraic semantics, infinitary logics, etc.). Full versions of selected papers will be published in a special issue of an international peer-reviewed journal (to be specified).

  • 18 - 20 November 2021, 32nd Novembertagung on the History and Philosophy of Mathematics "Mathematics in Times of Crisis", Virtual

    Date: 18 - 20 November 2021
    Location: Virtual
    Deadline: Thursday 1 July 2021

    The Novembertagung on the History and Philosophy of Mathematics is an annual international conference aimed at graduate students in the history and philosophy of mathematics and neighboring fields. It provides an opportunity for young researchers to present and discuss their research in a safe, informal environment, and serves as a place for them to share experience and advice, as well as to establish new contacts. Participants are welcome from around the world.

    On the Theme: Crisis, instability and times of uncertainty undoubtedly influenced the development of the sciences, and mathematics is no exception. Throughout history, mathematicians found themselves facing wide-ranging challenges, both internal and external to mathematics, to which they had to respond in new and creative ways. Inspired by contemporary global events, this conference is interested in the ways that times of crisis shaped the development of mathematics. The time of uncertainty might be frustrating and confounding for the mathematicians, but from a historical perspective it can be viewed as an engine of mathematical creativity.

    Abstracts, of around 250 words, should be submitted as a PDF file via email to . In your email, please also include your full name and affiliation as they should appear on the conference program. Please note that the theme serves as a guide, not a criterion for exclusion, and as such it is not necessary for a submission to engage with the theme to be accepted. However, establishing links with the theme will allow for more fruitful discussions, and as such is recommended.

  • 6 - 12 November 2021, 18th Conference on Principles of Knowledge Representation and Reasoning (KR2021), Hanoi, Vietnam

    Date: 6 - 12 November 2021
    Location: Hanoi, Vietnam
    Deadline: Wednesday 24 March 2021

    Knowledge Representation and Reasoning (KR) is a well-established and lively field of research. In KR a fundamental assumption is that an agent's knowledge is explicitly represented in a declarative form, suitable for processing by dedicated reasoning engines. This assumption, that much of what an agent deals with is knowledge-based, is common in many modern intelligent systems. Consequently, KR has contributed to the theory and practice of various areas in AI, including automated planning and natural language understanding, and to fields beyond AI, including databases, verification, software engineering, and robotics. In recent years, KR has contributed also to new and emerging fields, including the semantic web, computational biology, cyber security, and the development of software agents.

    The KR conference series is the leading forum for timely in-depth presentation of progress in the theory and principles underlying the representation and computational management of knowledge.

    We solicit papers presenting novel results on the principles of KR that clearly contribute to the formal foundations of relevant problems or show the applicability of results to implemented or implementable systems. We also welcome papers from other areas that show clear use of, or contributions to, the principles or practice of KR.

    In addition to the main conference track, KR2021 will host the following tracks and sessions:
    - Applications and Systems Track
     - Recently Published Research Track
     - Special Session on KR and Machine Learning
     - Special Session on KR and Robotics

    The KR2021 program will also feature workshops and tutorials, solicited by means of an open call, as well as a doctoral consortium.
    The Recently Published Research track, workshops, tutorials, and the doctoral consortium will have different submission and notification dates, which will be announced separately.

    Date: 6 - 8 November 2021
    Location: Hanoi, Vietnam (Virtual attendance)
    Deadline: Friday 25 June 2021

    NMR is the premier forum for results in the area of Non-Monotonic Reasoning. Its aim is to bring together active researchers in this broad field within knowledge representation and reasoning (KR), including belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, argumentation, causality, and many other related topics including systems and applications.

    NMR-21 will be co-located with the International Conference on Principles of Knowledge Representation and Reasoning (KR 2021).

    NMR-2021 invites contributions from the area of nonmonotonic, defeasible and default reasoning within the field of knowledge representation and reasoning (KR), including in particular belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, argumentation, causality, and many other related topics including systems and applications.

    The accepted papers will be published as a technical report and will be made available in the Computing Research Repository (CoRR) (https://arxiv.org/corr). Papers should be at most 10 pages in AAAI style including references, figures and appendices, if any. Papers already published or accepted for publication at other conferences are also welcome, provided that the original publication is mentioned in a footnote on the first page. In the same vein, papers under review for other conferences can be submitted with a similar indication on their front page. Papers that have already been published or submitted elsewhere may have any length.

  • 4 November 2021, Second Workshop on Second-Order Quantifier Elimination and Related Topics (SOQE 2021), Virtual

    Date & Time: Thursday 4 November 2021, 10:00-18:30
    Location: Virtual
    Deadline: Thursday 16 September 2021

    Second-order quantifier elimination (SOQE) is the problem of equivalently reducing a formula with quantifiers upon second-order objects such as predicates to a formula in which these quantified second-order objects no longer occur. In slight variations, SOQE is known as forgetting, projection, predicate elimination, and uniform interpolation. It can be combined with various underlying logics, including propositional, model, description and first-order logics. It is attractive as a logic-based approach to various computational tasks.

    The workshop aims to bring together researchers working on SOQE and all these related topics to present, discuss and compare issues shared by problems emerging from different special contexts, interesting open research problems (perhaps with partial solutions), new applications and implementation techniques. SOQE will be associated with the 18th International Conference on Principles of Knowledge Representation and Reasoning (KR 2021).

    We invite submissions of high-quality research on variants of SOQE and related topics, including work that describes applications, new systems or relevant data releases. Submissions will be reviewed by the program committee, which will select a balanced program of high-quality contributions.

    Submissions can be one of the following type:
    Regular paper: up to 11 pages + bibliography Short paper: up to 5 pages + bibliography
    Both regular and short papers should be written in English, formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS).
    Submissions must contain enough substance that it they can be cited in other publications and may not have appeared before.

    For more information, see http://2021.soqe.org/.
  • 4 - 5 November 2021, 2nd Workshop on Explainable Logic-Based Knowledge Representation (XLoKR 2021) , Hanoi, Vietnam (Virtually)

    Date: 4 - 5 November 2021
    Location: Hanoi, Vietnam (Virtually)
    Deadline: Friday 2 July 2021

    The problem of explaining why a consequence does or does not follow from a given set of axioms has been considered for full first-order theorem proving since at least 40 years, but there usually with mathematicians as users in mind. In knowledge representation and reasoning, efforts in this direction are more recent, and were usually restricted to sub-areas of KR such as AI planning and description logics. The purpose of this workshop is to bring together researchers from different sub-areas of KR and automated deduction that are working on explainability in their respective fields, with the goal of exchanging experiences and approaches.

    Sheila McIlraith and Joe Halpern will deliver the keynotes. The workshop will be co-located with KR 2021.

    Researchers interested in participating in the workshop should submit extended abstracts of 2-5 pages on topics related to explanation in logic-based KR. The papers should be formatted in Springer LNCS Style and must be submitted via EasyChair.

    The workshop will have informal proceedings, and thus, in addition to new work, also papers covering results that have recently been published or will be published at other venues are welcome.

  • 27 - 29 October 2021, 6th International Conference on the History and Philosophy of Computing (HaPoC 2021), Virtual & Zürich (Switzerland)

    Date: 27 - 29 October 2021
    Location: Virtual & Zürich (Switzerland)
    Deadline: Monday 3 May 2021

    The growing cultural import of computing practices has become ever more pressing in our days in all dimensions of social life. The global and collective nature of the challenges our epoch is facing (e.g. climate change, global pandemics, systemic inequalities, resurgence of totalitarianism, to name a few) requires a comprehensive perspective on computing, where social and cultural aspects occupy a central position. For these reasons, thinking about machines asks today for an interdisciplinary approach, where art is as necessary as engineering, anthropological insights as important as psychological models, and the critical perspectives of history and philosophy as decisive as the axioms and theorems of theoretical computer science.

    For more than a decade, the 'History and Philosophy of Computing' Conference (HaPoC) has contributed to building such an interdisciplinary community and environment. We aim to bring together historians, philosophers, computer scientists, social scientists, designers, manufacturers, practitioners, artists, logicians, mathematicians, each with their own experience and expertise, to take part in the collective construction of a comprehensive image of computing.

    For HaPoC 2021, we welcome contributions from researchers from different disciplinary horizons who intend to participate in the debate on the impact of computers on culture, science, and society from the perspective of their area of expertise, and who are open to engage in interdisciplinary discussions across multiple fields. Topics include but are not limited to:

    - Historical and philosophical perspectives on computing knowledge, objects and practices - Social, cultural and pedagogical aspects of computing - Computing and the human sciences - Epistemological dimensions of computing - Impact of computing technologies - Computing and the arts.

  • CfP post-proceedings of ITRS 2021: Intersection Types & Related Systems

    Deadline: Friday 1 October 2021

    ITRS workshops have been held every two years (with the exception of 2020). The ITRS 2021 workshop aimed to bring together researchers working on both the theory and practical applications of systems based on intersection types and related approaches. We are planning post-proceedings, including presentations to the workshop and submissions accepted via an open call.

    Papers should not be published elsewhere, with original results or surveying ongoing research. They should be written in English using LaTex and will appear on EPTCS. Submissions should be 20 pages long, excluding bibliography and avoiding technical appendices. Submissions are expected via EasyChair.

  • CfP Special Issue of Annals of Pure and Applied Logic (APAL) on “Combining Probability and Logic”

    Deadline: Thursday 30 September 2021

    We invite submissions for a Special Issue on “Combining Probability and Logic”, to be published with Annals of Pure and Applied Logic.

    Classically, logic and probability offer competing representations of partial or incomplete information, with the former assuming a qualitative perspective on uncertainty and the latter focusing on a quantitative account. Both provide their own policies for updating on new information, combining evidence from different sources, and acting under partial information.

    We solicit submissions of original papers that bridge these two perspectives. These could, for instance, connect representations of inductive reasoning in either setting, but they may also apply to specific sub-areas, such as game theory, network theory, causal modelling, machine learning, or maximum entropy reasoning. Likewise, the Special Issue is interested in articles that apply probabilistic tools to the study of logical systems or that use logical frameworks, classical or substructural, for understanding probabilistic approaches.

  • 28 - 30 September 2021, 12th International Conference on the Theory and Application of Diagrams (Diagrams 2021), Virtual

    Date: 28 - 30 September 2021
    Location: Virtual
    Deadline: Thursday 1 April 2021

    Diagrams 2021 is the twelth conference in the series that started in 2000. The multidisciplinary nature of Diagrams means it encompasses: architecture, art, artificial intelligence, biology, cartography, cognitive science, computer science, education, graphic design, history of science, human-computer interaction, linguistics, logic, mathematics, philosophy, psychology, and software modelling. The conference attracts a large number of researchers from these interrelated fields, positioning Diagrams as the major international event in the area.

    In addition to the Philosophy track, Diagrams 2021 will have two further tracks: Main, and Psychology and Education.

    The conference will include presentations of refereed Papers, Abstracts, and Posters, alongside a graduate symposium. We invite submissions for peer review that focus on any aspect of diagrams research, as follows: Long Papers (16 pages), Abstracts (3 pages), Short Papers (8 pages), Posters (4 pages). If the main research contribution of your submission is considered to fit either of the special tracks then you are strongly encouraged to submit to that track.

    We also invite proposals for tutorials of 1.5 hours in length. Tutorials are expected to address topics that are of interest to the Diagrams 2021 conference attendees. Tutorials differ from workshops in that they do not solicit contributions from attendees. Previously, attendees have particularly enjoyed tutorials that are interactive and spark debate. Tutorial submission deadline: April 30, 2021.

  • 20 - 27 September 2021, The 8th Workshop on Probabilistic Logic Programming (PLP 2021), Virtual

    Date: 20 - 27 September 2021
    Location: Virtual
    Deadline: Sunday 1 August 2021

    Probabilistic logic programming (PLP) approaches have received much attention in this century. They address the need to reason about relational domains under uncertainty arising in a variety of application domains, such as bioinformatics, the semantic web, robotics, and many more. Developments in PLP include new languages that combine logic programming with probability theory, as well as algorithms that operate over programs in these formalisms.

    The workshop encompasses all aspects of combining logic, algorithms, programming and probability and provides a forum for the exchange of ideas, presentation of results and preliminary work. After seven successful editions of this workshop, the eighth edition of PLP will be held at the ICLP virtual conference organised by the University of Porto. We hope that this encourages further collaboration between researchers in PLP and researchers working in other areas of ICLP.

    Submissions will be managed via EasyChair. Contributions should be prepared in the LNCS style. A mixture of papers are sought including: new results; work in progress; and technical summaries of recent substantial contributions.  Papers presenting new results should be 6-15 pages in length. Work in progress and technical summaries can be shorter (2-5 pages). The workshop proceedings will clearly indicate the type of each paper. At least one author of each accepted paper will be required to attend the workshop to present the contribution.

  • 17 September 2021, 5th International Workshop on Cognition and Ontologies (CAOS 2021), Bolzano (Italy) & Virtual

    Date & Time: Friday 17 September 2021, 09:45-13:30
    Location: Bolzano (Italy) & Virtual
    Deadline: Saturday 3 July 2021

    The purpose of the workshop is to bridge the gap between the cognitive sciences and research on ontologies and, thus, to create a venue for researchers interested in interdisciplinary aspects of knowledge representation. More specifically CAOS investigates how key cognitive phenomena and concepts (and the involved terminology) can be found across language, psychology and reasoning and how they can be formally and ontologically understood and analysed. It moreover seeks answers to ways such formalisations and ontological analysis can be exploited in Artificial Intelligence and information systems in general.

    CAOS 2021 is going to happen at the Bolzano Summer of Knowledge, BOSK 2021, in September 2021, organised as a FOIS 2021 workshop.  CAOS 2021 is planned as a hybrid event.

    We welcome submissions on topics related to the ontology of hypothesized building blocks of cognition (such as image schemas, affordances, categories, and related notions) and of cognitive capacities (such as concept invention, language acquisition and categorisation), as well as system demonstrations modelling these capacities in application settings. We also welcome submissions addressing the cognitive and epistemological adequacy of ontological modelling. Work in progress (short papers) are also welcome since a central goal of the workshop is the discussion of ongoing interdisciplinary work.

    We encourage three types of contributions: Full research papers (10-14 pages), Short papers (5-7 pages), and Abstracts for presentation (2-4 pages). All papers must be original and not submitted to or accepted by any other workshop, conference or journal.

  • September or December 2021, Workshop "Intuition & rigour in geometrical thinking from antiquity to the 19th century", Prague, Czech Republic

    Date: September or December 2021
    Location: Prague, Czech Republic
    Deadline: Friday 20 March 2020

    From the end of the 19th century, mathematical and philosophical literature has often portrayed a contrast between visual intuition and logical rigor. However, the terms "rigour" and "intuition" have rich associations and connotations in different historical contexts, and well before the turn of the 20th century. The goal of our workshop is to study the historical evolution of these notions within the mathematical practice, and the epistemological debates that they have raised.

    Confirmed keynote speakers are: Helena Durnova (Masaryk University, Brno) Michael Friedman (Humboldt University, Berlin) Eduardo Giovannini (University of Wien) Marco Panza (CNRS, Universit́e Paris 1/Chapman University) Vincenzo de Risi (CNRS, Universit́e Paris 7).

    Note: the event as it was scheduled cannot unfortunately take place in December due to covid measures, but will be postponed to the next year, possibly September 2021 or December 2021.

    In the workshop there are a few (cca 5) slots for contributed papers (30 min. presentation). We invite abstracts in accordance to the theme of the conference, Submissions of abstracts should not exceed 250 words, and must be written in English.

    8 - 9 September 2021, Seventh International Workshop on Controlled Natural Language (CNL 2020)

    Date: 8 - 9 September 2021
    Location: Amsterdam, the Netherlands & Online
    Target audience: researchers and practitioners
    Costs: €200 (small changes are possible)
    Deadline: Saturday 2 May 2020

    This workshop on Controlled Natural Language (CNL) has a broad scope and embraces all approaches that are based on natural language and apply restrictions on vocabulary, grammar, and/or semantics. This includes (but is certainly not limited to) approaches that have been called simplified language, plain language, formalized language, processable language, fragments of language, phraseologies, conceptual authoring, language generation, and guided natural language interfaces.

    Some CNLs are designed to improve communication among humans, especially for non-native speakers of the respective natural language. In other cases, the restrictions on the language are supposed to make it easier for computers to analyze such texts in order to improve computer-aided, semi-automatic, or automatic translations into other languages. A third group of CNL has the goal to enable reliable automated reasoning and formal knowledge representation from seemingly natural texts. All these types of CNL are covered by this workshop.

    Due to Covid-19, the workshop is postponed to 2021!

  • 8 - 10 September 2021, The 9th International Symposium on Symbolic Computation in Software Science (SCSS 2021), Virtual

    Date: 8 - 10 September 2021
    Location: Virtual
    Deadline: Tuesday 18 May 2021

    Symbolic Computation is the science of computing with symbolic objects (terms, formulae, programs, representations of algebraic objects etc.). Powerful algorithms have been developed during the past decades for the major subareas of symbolic computation: computer algebra and computational logic. Meanwhile, artificial intelligence methods and machine learning algorithms are widely used nowadays in various domains and, in particular, combined with symbolic computation. Several approaches mix artificial intelligence and symbolic methods and tools deployed over large corpora to create what is known as cognitive systems. Cognitive computing focuses on building systems which interact with humans naturally by reasoning, aiming at learning at scale.

    The purpose of SCSS 2021 is to promote research on theoretical and practical aspects of symbolic computation in software science, combined with modern artificial intelligence techniques.

    SCSS 2021 solicits submissions on all aspects of symbolic computation and their applications in software science, in combination with artificial intelligence and cognitive computing techniques. Original submissions are invited in two categories: regular research papers and tool papers. Regular research papers must not exceed 12 pages with up to 3 additional pages for technical appendices. Tool papers must not exceed 6 pages.

  • 1 - 3 September 2021, Third Biennial Conference on Language, Data and Knowledge (LDK2021), Zaragoza (Spain) and virtual

    Date: 1 - 3 September 2021
    Location: Zaragoza (Spain) and virtual
    Deadline: Sunday 21 March 2021

    This conference aims at bringing together researchers from across disciplines concerned with the acquisition, curation and use of language data in the context of data science and knowledge-based applications. This builds upon the success of the inaugural event held in Galway, Ireland in 2017 and the second LDK in Leipzig, Germany in 2019.

    In order to allow more people to attend the Conference physically, and due to the current state in the COVID-19 pandemic in Europe, we decided to postpone LDK 2021 to early September. The conference will allow remote presentations by participants who cannot attend the conference in person owing to COVID-19 travelling restrictions, but we do think that physical encounter and gossip leads to better research.

    We welcome submission of relevance to the topics listed below. Submissions can be in the form of:
    * Long research papers: 10-15 pages;
    * Short research or position papers: 6-8 pages;
    * Short scientific abstract submissions: be 4-6 pages.
    * Short abstracts on new challenges and research ideas ('Crazy New Ideas'): 1-4 pages.

    This year, we would like to propose a 'Crazy New Ideas' session that will be the occasion to present challenging research ideas that have not yet been fully explored, or you would like to see in ten years from now. Such ideas should be briefly presented in the form of a short abstract of one to four pages to initiate the discussions, which will also be included in the conference proceedings if permitted by the authors. This is your chance to be creative without censorship. Reviews for these abstract will focus on the potential of ideas to spark interesting discussions.

    Topics include Language Data, Knowledge Graphs, Applications for Language, Data and Knowledge, and Use Cases in Language, Data and Knowledge.

  • 9 - 13 August 2021, ESSLLI-2021 Workshop "Approaches to Implicature", Online via Zoom

    Date: 9 - 13 August 2021
    Location: Online via Zoom
    Deadline: Saturday 15 February 2020

    Recent work in implicature has seen a great deal of activity within two lines of research: the rational choice approach associated with game-theoretic pragmatics and the Bayesian Rational Speech Act framework, and the exhaustification-based approach. While these frameworks have generally been thought to be in theoretical tension, there are also underexplored ways to combine them, with the potential to benefit both approaches. The workshop will explore explicit comparisons between the two frameworks as well as efforts to combine them, with the hope of producing a more unified theory of implicature and a more general understanding of the data that such a theory must account for.

    We welcome 2-page abstracts for presentations on topics related to the workshop theme, with an optional 3rd page for references and large figures. Depending on submissions received, there may also be a poster session. Abstracts must be submitted in PDF format (12-point font, 1.5-cm or 1-in margins) to the Easychair site.

    Example topics of interest include but are not limited to: Applications of RSA or other game-theoretic or probabilistic pragmatics models to phenomena in semantics/pragmatics, Applications of exhaustification-based approaches to phenomena in semantics/pragmatics, Approaches to pragmatic inference that explicitly compare and/or combine theoretical perspectives, Theoretical, corpus-based, and experimental pragmatics, and Implicature, presupposition, not-at-issue content, expressive meaning, social meaning.

  • 9 - 10 August 2021, ESSLLI 2021 Workshop "Computational and Experimental Explanations in Semantics and Pragmatics"

    Date: 9 - 10 August 2021
    Location: Online
    Deadline: Monday 14 June 2021

    The field of natural language semantics has undergone what some refer to as an 'experimental turn' and is arguably currently undergoing a 'computational turn'. By expanding the toolbox available to the semanticist, these two turns have the effect of expanding the phenomena that can be explained and the varieties of semantic explanations that can be offered.

    Given this wider toolbox and purview, we aim to gather a workshop to showcase exciting new work that develops new semantic explanations using experimental and computational methods, as well as to invite broader reflection on the methodology of semantics now and in its future.

    Topics of potential interest include but are not limited to:
    • Experimental semantics and pragmatics
    • Graded/non-categorical semantic theories and explanations
    • Information-theoretic measures and explanations in semantics and pragmatics
    • Semantic universals
    • Learnability and evolution of semantics and pragmatics
    • Bayesian approaches to semantics and pragmatics
    • Probing neural models for learned semantic representations
    • Semantics in emergent communication protocols
    • The methodology of semantics

  • 26 - 31 July 2021, Workshop on Natural Formal Mathematics (NatFoM 2021), Virtual

    Date: 26 - 31 July 2021
    Location: Virtual
    Deadline: Thursday 1 July 2021

    In mathematics there has always existed a strong informal sense of "naturality". Natural theories, notions, properties, or proofs are prefered over technical, convoluted, or counterintuitive approaches. If formal mathematics is to become part of mainstream mathematics, its formalizations and user experience have to become more natural. This workshop, following a first edition in 2020, broadly addresses the issue of naturality in formal mathematics.

    NatFoM 2021 wil be held as part of the 14th Conference on Intelligent Computer Mathematics (CICM 2021).. Invited speaker: Jeremy Avigad.

    We call for submissions of extended abstracts (1 page) and demonstration proposals presenting work related to the workshop's topics of interest. Accepted abstracts can optionally be expanded to full papers (4 to 15 pages) to be published in proceedings on ceur-ws.org. To promote Natural Formal Mathematics, unfinished or exploratory work will also be welcome. Extended abstracts and papers should be formatted in LaTeX using the style onecolceurws.

  • 21 - 24 July 2021, 15th International Conference on Deontic Logic and Normative Systems (DEON 2020/21), Online

    Date: 21 - 24 July 2021
    Location: Online
    Costs: No registration fees
    Deadline: Sunday 21 February 2021

    The biennial DEON conferences are designed to promote interdisciplinary cooperation amongst scholars interested in linking the formal-logical study of normative concepts, normative language and normative systems with computer science, artificial intelligence, linguistics, philosophy, organization theory and law. In addition to these general themes, DEON 2020/21 will encourage a special focus on the topic 'Norms in Social Perspective'.

    Keynote speakers: Marcia Baron (Indiana University, Bloomington), Emiliano Lorini (IRIT-CNRS, Toulouse University, France), Shyam Nair (Arizona State University, Tempe), and Sonja Smets (ILLC, University of Amsterdam).

    We hope the global and local situation will allow us to hold the conference in person. If that will not be the case, we are prepared to hold the conference online, partially or totally. Contributors will be informed in advance.

    Authors are invited to submit an original, previously unpublished, short research paper pertaining to any of DEON topics. The paper should be in English, anonymized, and should be no longer than 15 pages (including notes and appendix, but excluding bibliography). The submission of a short abstract must precede the paper’s submission.

    Due to COVID-19, we had to postpone the DEON conference to the summer of 2021. A first round of papers was already selected last summer. With this extra call for new submissions, we hope to attract authors who were not already accepted within last summer's round. Selected submissions for this round will be published in the proceedings together with those of the first round, and presented at the conference. We strongly encourage women and other members of under-represented groups in academia to submit a paper.

  • 21 July 2021, The Seventh International Workshop on Proof eXchange for Theorem Proving (PxTP 2021), Virtual

    Date: Wednesday 21 July 2021
    Location: Virtual
    Deadline: Wednesday 21 April 2021

    The progress in computer-aided reasoning, both automatic and interactive, during the past decades, has made it possible to build deduction tools that are increasingly more applicable to a wider range of problems and are able to tackle larger problems progressively faster. In recent years, cooperation of such tools in larger verification environments has demonstrated the potential to reduce the amount of manual intervention. Examples include the Sledgehammer tool providing an interface between Isabelle and (untrusted) automated provers, and collaboration of the HOL Light and Isabelle systems in the formal proof of the Kepler conjecture.

    Cooperation between reasoning systems relies on availability of theoretical formalisms and practical tools for exchanging problems, proofs, and models. The PxTP workshop strives to encourage such cooperation by inviting contributions on suitable integration, translation, and communication methods, standards, protocols, and programming interfaces. The workshop welcomes developers of automated and interactive theorem proving tools, developers of combined systems, developers and users of translation tools and interfaces, and producers of standards and protocols. We are interested both in success stories and descriptions of current bottlenecks and proposals for improvement.

    Topics of interest for this workshop include all aspects of cooperation between reasoning tools, whether automatic or interactive. Researchers interested in participating are invited to submit either an extended abstract (up to 8 pages) or a regular paper (up to 15 pages). Submitted papers should describe previously unpublished work, and must be prepared using the LaTeX EPTCS class. Submissions will be refereed by the program committee, which will select a balanced program of high-quality contributions. Short submissions that could stimulate fruitful discussion at the workshop are particularly welcome. We expect that one author of every accepted paper will present their work at the workshop.

    Location: Virtual
    Deadline: Monday 15 March 2021

    The CIAA conferences concern research on all aspects of implementation and application of automata and related structures, including theoretical aspects. Automata theory is the foundation of computer science. Its applications have spread to almost all areas of computer science and many other disciplines. The purpose of these conferences is to bring together members of the academic, research and industrial community who have an interest in implementation and application of automata to demonstrate and analyze their work and to explain the problems they have been solving.

    Note: Remote attendance will be possible, regardless of whether or not there will be a physical meeting.

    Original papers are sought in all areas that relate to implementation and application of automata. Submissions must be written in LaTeX using the LNCS style and must not exceed 12 pages, bibliography included. Simultaneous submissions of papers to journals or any other conference with published proceedings, or submitting previously published papers is not allowed.The proceedings will be published in the Springer LNCS series and will be available at the conference. A "Best Paper Award," since 2014 called "Sheng Yu Award" will be presented to the author(s) of the paper judged to be the best on the basis of the referee reports.

  • 18 July 2021, 35th International Workshop on Unification (UNIF 2021), Virtual

    Date: Sunday 18 July 2021
    Location: Virtual
    Deadline: Friday 16 April 2021

    Unification is concerned with the problem of identifying given (first- or higher-order) terms, either syntactically or modulo a theory. It is a fundamental technique that is employed in various areas of Computer Science and Mathematics. In particular, unification algorithms are key components in completion of term rewriting systems, resolution-based theorem proving, and logic programming. But unification is, for example, also investigated in the context of natural language processing, program analysis, types, modal logics, and in knowledge representation.

    UNIF 2021 is the 35th in a series of annual workshops on unification and related topics. Just as it predecessors', the purpose of UNIF 2021 is to bring together researchers interested in unification theory and its applications, as well as closely related topics, such as matching (i.e., one-sided unification), anti-unification (i.e., the dual problem to unification), disunification (i.e., solving equations and inequations) and the admissibility problem (which generalizes unification in modal logics). It will provide a forum for presenting recent (even unfinished) work, and discuss new ideas and trends in this and related fields. UNIF 2021 is associated with FSCD 2021 and will be a purely virtual event.

    Following the tradition of UNIF, we call for submissions of extended abstracts (5 pages) in EasyChair style. Topics of interest of the workshop include syntactic and equational unification algorithms, matching and constraint solving, unification in modal, temporal, and description logics, higher-order unification, narrowing, disunification, anti-unification, complexity issues, combination methods, implementation techniques, and applications. We also allow submission of work presented/submitted in/to another conference.

  • 12 July 2021, 2nd Workshop on Verification of Session Types (VEST 2021), Online

    Date: Monday 12 July 2021
    Location: Online
    Deadline: Monday 3 May 2021

    Stateful entities offer services in a non-uniform way (one cannot pop from an empty stack). Traditional type systems cannot guarantee that operations are only invoked when the entity is in the right state. Session types are abstract representations of the sequences of operations that computational entities (such as channels or objects) must perform. Although the foundations of session types are now well established, and new works build on approaches that have become standard, there is still a lack of reusable libraries, namely machine-verified ones.

    The goal of the VEST workshop is to gather the researchers working on mechanisations of behavioural types using various theorem provers, such as Agda, Coq, Isabelle or any other. The workshop will be a platform to present both the now well-established efforts and the ongoing works the community has put on verification. The workshop will also be a forum to discuss strengths and weaknesses of existing approaches, potential obstacles and to foster collaboration.

    We request two types of research contributions.
    Type 1: Short presentations (1 page) of work published elsewhere;
    Type 2: Presentations (2-5 pages) of ongoing original work.
    Submissions of Type 1 will consist of 1 page papers presenting the work, the publication venue and the significance of the results; the PC will select the submissions with a ranking system.
    Submissions of Type 2 will consist of 2 - 5 page papers submitted to a light reviewing process.
    There will be no proceedings of VEST'21, but rather the aim is to strengthen and further expand our community.

  • 12 July 2021, Formal Methods Education Online: Tips, Tricks & Tools (FOMEO'21), Virtual

    Date: Monday 12 July 2021
    Location: Virtual
    Deadline: Saturday 8 May 2021

    Online instruction of formal methods has been a challenge in the last year, including teaching of basics of logics and automata theory, formal verification, theorem proving etc. This satellite workshop of ICALP brings together instructors of formal methods as well as developers of teaching support systems for formal methods to (1) present tools supporting teaching of formal methods education, and (2) discuss tips, tricks & experiences in online instruction gained in the last year.

    You can submit your contribution at EasyChair. Submissions should contain a title, a short abstract (to be published as part of the program) as well as a short description of how you plan to present (e.g. talk/live demo and/or poster/demo exhibition booth). The time slots for presentations can vary, as we expect short presentations of tips&tricks but also some longer demos of tools. In the gather-town-like sessions, every presenter/project will have a presentation area where demos, poster presentation, etc. (presenters have complete freedom) are possible.

  • 5 - 9 July 2021, International Workshop on Quantified Boolean Formulas and Beyond (QBF 2021), Virtual

    Date: 5 - 9 July 2021
    Location: Virtual
    Deadline: Monday 31 May 2021

    Quantified Boolean formulas (QBF) are an extension of propositional logic which allows for explicit quantification over propositional variables. Many problems from application domains such as model checking, formal verification or synthesis are PSPACE-complete, and hence could be encoded in QBF in a natural way. However, in contrast to SAT, QBF is not yet widely applied to practical problems in academic or industrial settings. The goal of the International Workshop on Quantified Boolean Formulas (QBF Workshop) is to bring together researchers working on theoretical and practical aspects of QBF solving. In addition to that, it addresses (potential) users of QBF in order to reflect on the state-of-the-art and to consolidate on immediate and long-term research challenges.

    QBF 2021 is affiliated to and co-located with: Int. Conf. on Theory and Applications of Satisfiability Testing (SAT 2021) July 5-9, 2021. The workshop also welcomes work on reasoning with quantifiers in related problems, such as dependency QBF (DQBF), quantified constraint satisfaction problems (QCSP), and satisfiability modulo theories (SMT) with quantifiers.

    The workshop is concerned with all aspects of current research on all formalisms enriched by quantifiers, and in particular QBF. Submissions of extended abstracts are invited and will be managed via Easychair. In particular, we invite the submission of extended abstracts on work that has been published already, novel unpublished work, or work in progress, as well as proposals for short tutorial presentations. Submissions which describe novel applications of QBF or related formalisms in various domains are particularly welcome.

    Each submission should have an overall length of 1-4 pages in LNCS format. Authors may decide to include an appendix with additional material.

  • 14 - 18 June 2021, Second NAtural LOgic meets MAchine Learning Workshop (NALOMA'21), Online, Netherlands

    Date: 14 - 18 June 2021
    Location: Online, Netherlands
    Deadline: Friday 26 March 2021

    After the successful completion of NALOMA'20 (NAtural LOgic Meets MAchine Learning), NALOMA'21 seeks to continue the series and attract exciting contributions.  NALOMA'21 is set out to address two main issues of the NLI community. First, the approaches and systems currently used to address NLI are too one-dimensional: they are either purely DL or purely symbolic but do not attempt to combine the two worlds. A second issue concerns datasets: existing NLI datasets are either complex enough but too small to be used for proper learning, or large enough but too easy to be claimed to represent human inference. The workshop aims to bridge the gap between ML/DL and symbolic/logic-based approaches to NLI, and it is perhaps the only workshop organized to do so. It will take place from June 14-June 18, 2021, during the International Conference on Computational Semantics (IWCS 2021) organized by the University of Groningen but taking place fully online due to the pandemic.

    The workshop invites submissions on any (theoretical or computational) topic concerning NLI.
    We invite two types of submission:
    - Archival (long or short) papers should report on complete, original and unpublished research. Accepted papers will be published in the workshop proceedings and appear in the ACL anthology.
    - Extended abstracts may report on work in progress or work that was recently published/accepted at a different venue.

  • 14 - 18 June 2021, First Workshop on Multimodal Semantic Representations (MMSR 2021): Beyond Language, Virtual

    Date: 14 - 18 June 2021
    Location: Virtual
    Deadline: Friday 26 March 2021

    The demand for more sophisticated natural human-computer and human-robot interactions is rapidly increasing as users become more accustomed to conversation-like interactions with AI and NLP systems. Such interactions require not only the robust recognition and generation of expressions through multiple modalities (language, gesture, vision, action, etc.), but also the encoding of situated meaning.

    This workshop intends to bring together researchers who aim to capture elements of multimodal interaction such as language, gesture, gaze, and facial expression with formal semantic representations. We provide a space for both theoretical and practical discussion of how linguistic co-modalities support, inform, and align with 'meaning' found in the linguistic signal alone. MMSR 2021 is co-located with IWCS 2021.

    We solicit papers on multimodal semantic representation. Two types of submissions are solicited: long papers and short papers. Long papers should describe original research and must not exceed 8 pages, excluding references. Short papers (typically system or project descriptions, or ongoing research) must not exceed 4 pages, excluding references. Both types will be published in the workshop proceedings and in the ACL Anthology. Accepted papers get an extra page in the camera-ready version. We strongly encourage students to submit to the workshop and will consider a student session depending on the number of submissions.

  • 14 - 18 June 2021, Workshop on Semantic Spaces at the Intersection of NLP, Physics, & Cognitive Sciences (SemSpace2021), Online

    Date: 14 - 18 June 2021
    Location: Online
    Deadline: Tuesday 6 April 2021

    Semantic Spaces at the Intersection of NLP, Physics, and Cognitive Science (SemSpace2021) is the latest edition of a series of workshops that brings together research at the intersection of NLP, Physics, and Cognitive Science. Using the common ground of vector spaces, the workshop offers researchers in these areas an appropriate forum for presenting their uniquely motivated work and ideas. The interplay between the three disciplines will foster theoretically motivated approaches to understanding how meanings of words interact with each other in sentences and discourse via grammatical types, how they are determined by input from the world, and how word and sentence meanings interact logically.

    This year we are excited to be (virtually) co-located with IWCS.

    We welcome two types of submission:
    - Archival papers of up to 8 pages should report on complete, original and unpublished research.
    - Extended abstracts (up to 3 pages) may report on work in progress or work that was recently published/accepted at a different venue.
    Papers should be formatted following the common two-column structure as used by ACL. Please use the IWCS specific style-files or the Overleaf template, taken from ACL 2021.

TYPES 2021 will not only consist of presentations, but also a setup of working groups that get together throughout the week. The hope is that we can retain at least some of the exchange and chatter that is the heart of the TYPES conference series.

    TYPES solicits contributed talks to stimulate discussions. The contributed talks are selected on the base of extended abstracts/short papers of 2 pages (excluding bibliography) formatted with the LaTeX EasyChair3.5. We encourage talks proposing new ways of applying type theory. In the spirit of workshops, talks may be based on newly published papers, work submitted for publication, but also work in progress.

  • CfP special issue of the journal "Theoria" on Thin Objects

    Deadline: Tuesday 1 June 2021

    In his recent book 'Thin Objects: An Abstractionist Account' (Oxford University Press, 2018), Øystein Linnebo claims that mathematical objects are thin in the sense that "very little is required for their existence". Linnebo articulates this view in terms of Fregean abstraction principles, arguing that it is sufficient for abstract objects to exist that some nonabstract objects, or pluralities thereof, stands in the appropriate equivalence relations. Linnebo set up, among others, a defence of predicative vis-á-vis impredicative abstraction, and articulates a 'dynamic' approach to abstraction itself, on which abstraction is taken to extend the domain of objects available for quantification, and predicative abstraction is iterated over larger and larger domains.

    The goal of this Special Issue is to bring together contributions addressing both the philosophical and the technical aspects of Linnebo's book, also in connection to similar proposals in the philosophy of mathematics and logic. Contributions to the Special Issue should consist in short papers (4000-6000 words). Øystein Linnebo will contribute a précis of his book, opening the issue, and a 'Reply to Critics', closing the issue.

  • 24 - 28 May 2021, Thirteenth NASA Formal Methods Symposium (NFM 2021), Virtual

    Date: 24 - 28 May 2021
    Location: Virtual
    Deadline: Friday 27 November 2020

    The widespread use and increasing complexity of mission-critical and safety-critical systems at NASA and in the aerospace industry require advanced techniques that address these systems' specification, design, verification, validation, and certification requirements. The NASA Formal Methods Symposium (NFM) is a forum to foster collaboration between theoreticians and practitioners from NASA, academia, and industry. NFM's goals are to identify challenges and to provide solutions for achieving assurance for such critical systems.

    New developments and emerging applications like autonomous software for Unmanned Aerial Systems (UAS), UAS Traffic Management (UTM), advanced separation assurance algorithms for aircraft, and the need for system-wide fault detection, diagnosis, and prognostics provide new challenges for system specification, development, and verification approaches. Similar challenges need to be addressed during development and deployment of on-board software for both spacecraft and ground systems. The focus of the symposium will be on formal techniques and other approaches for software assurance, including their theory, current capabilities and limitations, as well as their potential application to aerospace, robotics, and other NASA-relevant safety-critical systems during all stages of the software life-cycle.

    Due to the COVID-19, the organizers have decided to hold NFM 2021 virtually only, rather than in person.

    We encourage submissions on cross-cutting approaches that bring together formal methods and techniques from other domains such as probabilistic reasoning, machine learning, control theory, robotics, and quantum computing among others.

    There are two categories of submissions:
    1. Regular papers describing fully developed work and complete results (maximum 15 pages);
    2. Short papers on tools, experience reports, or work in progress with preliminary results (maximum 6 pages).
    All papers must be in English and describe original work that has not been published or submitted elsewhere.

  • Postponed, Trends in Logic XX "Logic and Reasoning: Formal and Informal", Kyiv, Ukraine

    Date: Postponed
    Location: Kyiv, Ukraine
    Target audience: Researchers in logic
    Costs: Conference fee: 160/190 EUR
    Deadline: Friday 31 January 2020

    Reasoning is at the very heart of logic, constituting its subject matter. In the last few decades, there has been considerable progress both in the purely logical analysis of reasoning and in applied logical investigations of various concrete subject domains, such as philosophical and scientific discourse, logic programming and everyday communication. Along with further elaboration of standard techniques a range of other approaches and semantic modeling of logical systems are being developed. Moreover, there is a powerful tradition of analyzing and evaluating reasoning patterns by means of informal logic and argumentation theory. The aim of the conference is to bring together scholars working in various areas of proof-theoretic, semantic, argumentative and informal logic analysis.

    Invited Speakers: Hans van Ditmarsch (French National Centre for Scientific Research, France), Valentin Goranko (Stockholm University, Sweden), Dale Hample (University of Maryland, USA) and Hitoshi Omori (Ruhr-University Bochum, Germany).

    Due to the continuing coronavirus pandemic, the event in May 2021 has been suspended, but the organizers hope to hold the conference in Kyiv as soon as circumstances permit, as well as hold the regular conference in May 2022.

    Abstracts of at most three pages length (including references) should be submitted electronically as pdf documents using the EasyChair submission page. At least one author of each accepted paper must register for, and attend the conference to present her or his work.

  • 3 - 4 May 2021, International Workshop on Logical Aspects of Multi-Agent Systems & Strategic Reasoning (LAMAS & SR 2021), Virtual

    Date: 3 - 4 May 2021
    Location: Virtual
    Deadline: Wednesday 10 February 2021

    Logics and strategic reasoning play a central role in multi-agent systems. Logics can be used, for instance, to express the agents' abilities, knowledge, and objectives. Strategic reasoning refers to algorithmic methods that allow for developing good behavior for the agents of the system. At the intersection, we find logics that can express existence of strategies or equilibria, and can be used to reason about them.

    The LAMAS&SR workshop merges two international workshops: LAMAS, which focuses on all kinds of logical aspects of multi-agent systems from the perspectives of artificial intelligence, computer science, and game theory, and SR, devoted to all aspects of strategic reasoning in formal methods and artificial intelligence. Over the years the communities and research themes of both workshops got closer and closer. LAMAS&SR unifies LAMAS and SR under the same flag, formally joining the two communities in order to expose each of them to a wider range of work relevant to their research.

    LAMAS&SR 2021 will be held with AAMAS 2021 Online.

    Authors are invited to submit extended abstracts of 2 pages plus 1 page for references in the AAMAS format. Both published and unpublished works are welcome. Submissions are subject to a single-blind review process (submissions should not be anonymous).

    There will be no formal proceedings, but accepted extended abstracts will be made available on the workshop's website. We envisage that extensions of selected papers will be invited to a journal.

  • CfP special issue of Annals of Pure and Applied Logic (APAL) on "Logics of Dependence & Independence"

    Deadline: Sunday 28 February 2021

    Logics of dependence and independence are novel non-classical logics aiming at characterizing dependence and independence notions in philosophy and in social and physical sciences. This field of research has grown rapidly in recent years. This family of logics has found applications in fields such as database theory, linguistics, social choice, quantum physics along with other fields. This special issue aims to provide a snapshot of the state of the art of logics of dependence and independence.

    The special issue is related to the topics of the Workshop on Logics of Dependence and Independence.Participants of the workshop, as well as other authors are invited to submit contributions.

  • CfP special issue of "Journal of Logic and Computation" (JLC) on "Reasoning about Social Networks"

  • CfP special issue of Logic and Logical Philosophy on "Logics & their interpretations"

    Deadline: Saturday 20 February 2021

    Logical systems of classical and non-classical sorts are often endowed with a variety of interpretations: semantic, proof-theoretic, metaphysic, epistemic, pragmatic, informational, dialogical, and more. Work along these lines has led to the connection of logic to many other areas of knowledge and research. The attempt to draw these connections is, however, sometimes met with a number of criticisms. On the one hand, many of these interpretations have been subject to discussion, trying to determine if the conceptual and the formal aspects align as required. On the other hand, scholars who reject some contentions interpretations of certain formal systems debate whether these logics should be dispensed with in light of their philosophical interpretations, or whether it is possible to embrace them without endorsing such interpretations. Examples of the above are the debates between the fictionalist and the realist interpretations of possible worlds for modal logics, and between the dialetheic and the epistemic interpretations of paraconsistent logics. Furthermore, there is a question of which if any is the canonical application of logic as a discipline and therefore of any given logical system. In this vein, some scholars believe that a distinction between pure logic and applied logic needs to be taken into account, which may or may not resemble the medieval divide between logica docens and logica utens.

    The aim of this special issue is to discuss these topics and to assess the effect of the answers provided in the relation between logic and the many disciplines related to it. Contributions are welcome from philosophers, logicians, mathematicians, linguists, and computer scientists. Submissions must be in English and use the form of a source LaTeX file.

  • 4 - 6 February 2021, ICAART Session "Natural Language Processing in Artificial Intelligence" (NLPinAI 2021), Online

    Date: 4 - 6 February 2021
    Location: Online
    Deadline: Thursday 26 November 2020

    Computational and technological developments that incorporate natural language are proliferating. Adequate coverage encounters difficult problems related to partiality, underspecification, and context-dependency, which are signature features of information in nature and natural languages. Furthermore, agents (humans or computational systems) are information conveyors, interpreters, or participate as components of informational content. Generally, language processing depends on agents' knowledge, reasoning, perspectives, and interactions.

    The session covers theoretical work, applications, approaches, and techniques for computational models of information and its presentation by language (artificial, human, or natural in other ways). The goal is to promote computational systems of intelligent natural language processing and related models of thought, mental states, reasoning, and other cognitive processes.

    We invite contributions relevant to the following topics. All accepted papers will be published in a special section of the conference proceedings bookm and be made available at the SCITEPRESS Digital Library.

  • 15 - 17 January 2022, HOLIC Workshop “Textual Analysis as the Basis for Understanding Chinese Logical Thought”

    Date & Time: 15 - 17 January 2022, 16:30-22:00
    Location: Online
    Costs: Free

    There is a wealth of early Chinese philosophical texts from the Hundred Schools of Thought, dating from the 6th century BC to 221 BC. These texts contain profound ideas on how to think, reason, and conduct argumentation, as well as the relationship between ming 名 (name) and shi 实 (object/reality), language and logic. Many ideas of these texts continued to be influential throughout Chinese history, and are still of great relevance to today’s world.

    Prominent scholars have made great contributions in analysing and interpreting these texts. In China, Sun Yirang started the tradition of textual analysis in the late Qing Dynasty, and it has been continued by Hu Shi, Feng Youlan, Shen Youding, Wu Yujiang, among many others. The HOLIC workshops are carrying on this tradition with particular attention to logical thought and to facilitate the Handbook project. The workshop holds that any idea or theories presented should be firmly based on textual evidence, yet we are open to a variety of methodological approaches.

  • 15 January 2022, Workshop "Formalize!(?) 2", Virtual

    Date & Time: Saturday 15 January 2022, 15:15-19:45
    Location: Virtual

    We are organizing a one-day online workshop to commemorate the World Logic Day, on the topic of formalization in mathematics. Registration is free of charge and everybody is welcome to attend.

    Topic: What are the chances and problems of the act of formalization in the context of mathematics? It is often said, that all of mathematics can be reduced to first-order logic and set theory. The derivation indicator view says that all proofs stand in some relation to a derivation, i.e. a mechanically checkable syntactical objects following fixed rules, that would not have any gaps. For a long time this was a mere hope. There may have been proofs of concepts from early logicists but derivation never played a big role in mathematical practice. The modern computer might change this. Interactive and automated theorem provers promise to make the construction of a justification without any gaps feasible for complex mathematics. Is this promise justified? Will the future of mathematical practice shift to more formal mathematics? Should it? We hope to illuminate such questions and focus especially on what these developments mean for the future of the curriculum of university students. This event features speakers speaking about both concrete projects and reflections on such endeavours in general.

  • 14 January 2022, UNESCO World Logic Day 2022

    Date & Time: Friday 14 January 2022, 00:01-23:59

    UNESCO proclaimed 14 January to be World Logic Day, a global day of supporting the development of logic through teaching and research, as well as to public dissemination of the discipline.

    The coordination of World Logic Day 2021 is --for the second time-- in the hands of the Conseil International de Philosophie et des Sciences Humaines (CIPSH) and its member organization, the DLMPST/IUHPST.

    We would like to encourage logicians all around the world to organize (possibly small) events in close proximity to 14 January 2022 to celebrate this day. It is impossible to predict what type of meeting will be possible in January 2022 and what the international travel situation will be. As a consequence, we should like to ask all organisers to weigh pros and cons of planning in person events, purely online events, or hybrid events before making an announcement. Note that online and hybrid events have the advantage of allowing easy access of people from around the world. Registered events will be listed on the CIPSH website.

  • Wittgenstein & the formal sciences (WLD 2022 event), Virtual

    Location: Virtual

    We are organizing a one-day online workshop to commemorate the World Logic Day.

    Ludwig Wittgenstein, despite being one of the most influential philosophers of the 20th Century, is often perceived as confusing and misunderstood. Furthermore, in spite of Wittgenstein's belief that his most important work was his philosophy of mathematics, his work on it is generally more unknown than the rest. Given the potential of his work in areas like the philosophy of mathematical practice, ethnomathematics, and even the development of AI, this workshop aims at discussing it and raising its visibility.

  • 7 - 14 January 2022, Formal Ethics 2022 Conference (FE2022), Virtual

    Date: 7 - 14 January 2022
    Location: Virtual

    We are pleased to announce the eighth edition of the Formal Ethics conference series. Formal Ethics 2022 will be held online using Zoom this coming January 7th, 8th, 13th, and 14th (for most time zones). The keynote address will be given by Matthew Adler (Duke Law School). In addition, there will be sixteen contributed papers. Most of the papers were originally scheduled to be presented at the in-person Formal Ethics conference that was to be held at Vanderbilt University in 2020 but that was cancelled because of COVID.

    Formal Ethics is a common denominator for the application of tools from logic, decision theory, game theory, and social choice theory to the analysis of concepts in moral and political philosophy and to the development of ethical theory. It is a rapidly growing field of research that goes back to the work of Kenneth Arrow, Amartya Sen, John Harsanyi, Georg Henrik von Wright, and others. The field has recently gained new impetus with formal work on non-classical logic, freedom and responsibility, population ethics, value theory, and the evolution of norms and conventions.

It will focus on discussing the following four recent monographs: Igor Douven's "The theory and Practice of Abduction" (forthcoming), Ilkka Niiniluotto's "Truth-Seeking by Abduction" (2018), John Norton's "The Material Theory of Induction" (2021), and Gerhard Schurz' "Hume's Problem Solved" (2019). Each of these monographs will be discussed in form of a comprehensive comment as well as replies and reflections by the authors. The workshop will also host specialist talks from leading scholars in this field of research.

  • 28 - 30 September 2021, Minisymposium "Large cardinals", Virtual (Passau, Austria)

    Date: 28 - 30 September 2021
    Location: Virtual (Passau, Austria)

    This minisymposium will be devoted to recent developments in the theory of large cardinals, a central concept of contemporary set theory that allows the measurement of the consistency strength of mathematical theories and the ordering of these theories into a canonical hierarchy. Seminal results show that large cardinal assumptions themselves answer many important questions left open by the standard axiomatization of set theory and this leads many set theorists to think that these axioms should be included in the correct axiomatization of mathematics. In the last fifty years, set theorists have developed a deep and canonical theory of large cardinals and, in recent years, breakthrough results in vastly different regions of the large cardinal hierarchy were obtained. The talks in our symposium will cover this wide spectrum of research, from virtual large cardinal axioms in the lower reaches of this hierarchy all the way up to axioms of infinity that contradict the Axiom of Choice.

  • 27 September 2021, Minisymposium "Thinking about proofs" (at DMV-OeMG conference), Virtual

    Date & Time: Monday 27 September 2021, 15:00-18:00

    It is often said, that all of mathematics can be reduced to first-order logic and set theory. The derivation indicator view says that all proofs stand in some relation to a derivation, i.e. a mechanically checkable syntactical objects following fixed rules, that would not have any gaps. For a long time this was a mere hope. There may have been proofs of concepts from early logicists but derivation never played a big role in mathematical practice. The modern computer might change this. Interactive and automated theorem provers promise to make the construction of a justification without any gaps feasible for complex mathematics. This minisymposium brings together philosophers, educators and linguist to study both proofs as they can be found in real textbook as well as in the logical sense, i.e. derivations.

    This is an affiliated minisymposium to the DMV and ÖMG-annual meeting.

  • 13 - 14 September 2021, 5th International Autumn School "Proof and Computation" , Online

    Date: 13 - 14 September 2021
    Location: Online
    Target audience: Graduate or PhD students and young postdoctoral researchers

    The aim of  the autumn school "Proof and Computation" is to bring together young researchers in the field of Foundations of Mathematics, Computer Science and Philosophy. Scope: Predicative Foundations, Constructive Mathematics and Type Theory, Computation in Higher Types, and  Extraction of Programs from Proofs. There will be an opportunity to form ad-hoc groups working on specific projects, but also to discuss in more general terms the vision of constructing correct programs from proofs.

    Unfortunately because of the present situation we had to cancel the event. More precisely, it will be held as an online workshop from 13th to 14th September 2021.

  • 8 - 10 September 2021, The 17th Reasoning Web Summer School (RW 2020) , Virtual

    Date: 8 - 10 September 2021
    Location: Virtual

    The purpose of the Reasoning Web Summer School is to disseminate recent advances on reasoning techniques and related issues that are of particular interest to Semantic Web and Linked Data applications. It is primarily intended for postgraduate (PhD or MSc) students, postdocs, young researchers, and senior researchers wishing to deepen their knowledge. As in the previous years, lectures in the summer school will be given by a distinguished group of expert lecturers carefully selected to cover a wide range of topics relevant to the school (see below).

    The summer school is part of Declarative AI 2021 and is co-located with RuleML+RR 2021 and DecisionCAMP 2021. The students attending the RW school are particularly encouraged to also apply to the Doctoral Consortium of RuleML+RR. The number of attendees will be limited and participation will depend on submitting an application which will undergo a reviewing process.
