  • CfP special issue of EJPS on "Dimensions of Applied Maths"

    Deadline: Sunday 31 May 2020

    Davide Rizza and Matt Parker are editing one of the forthcoming EJPS (European Journal of Philosophy of Science) topical collections, on "Dimensions of Applied Mathematics".

    Philosophical interest in the application of mathematics has usually been connected to indispensability arguments or Wigner’s famous puzzle of ‘unreasonable effectiveness’. In both cases the success of mathematical applications has been taken as a  starting point for philosophical reflection and, as a result, little attention has been paid to the practice of applying mathematics in the course of scientific enquiry. This special issue is devoted to exploring the latter, relatively neglected topic. We encourage submissions, especially from non-mainstream areas of philosophy of science and/or from under-represented groups, discussing any of the dimensions (historical, foundational and practical) of applied mathematics.

    For more information, see http://www.philsci.eu/page-1075519.

  • 27 - 31 July 2020, Workshop on Natural Formal Mathematics

    Date: 27 - 31 July 2020
    Location: Online
    Deadline: Monday 15 June 2020

    In (pure) 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 broadly addresses the issue of naturality in formal mathematics.

    This workshop is part of the 13th Conference on Intelligent Computer Mathematics (CICM 2020).

    We call for submissions of extended abstracts and demonstration proposals presenting work related to the workshop's theme. To promote Natural Formal Mathematics unfinished or exploratory work will also be welcome. Details can be found on the webpage.

    For more information, see https://cicm-conference.org/2020/cicm.php?event=NFM or contact Florian Rabe at , or Peter Koepke at .
  • 9 - 10 October 2020, 3rd International Workshop on Dynamic Logic: New Trends and Applications (DaLí 2020), Prague, Czech Republic

    Date: 9 - 10 October 2020
    Location: Prague, Czech Republic
    Deadline: Saturday 20 June 2020

    Building on the pioneer intuitions of Floyd-Hoare logic, dynamic logic was introduced in the 70's as a suitable logic to reason about, and verify, classic imperative programs. Since then, the original intuitions grew to an entire family of logics, which became increasingly popular for assertional reasoning about a wide range of computational systems. Simultaneously, their object (i.e. the very notion of a program) evolved in unexpected ways. This lead to dynamic logics tailored to specific programming paradigms and extended to new computing domains, including probabilistic, continuous and quantum computation. Both its theoretical relevance and practical potential make dynamic logic a topic of interest in a number of scientific venues, from wide-scope software engineering conferences to modal logic specific events. However, no specific event is exclusively dedicated to it. This workshop aims at filling fill such a gap, joining an heterogeneous community of colleagues, from Academia to Industry, from Mathematics to Computer Science.

    Invited Speakers: Johan van Benthem

    Submissions are invited on the general field of dynamic logic, its variants and applications. Submissions of original papers (unpublished and not submitted for publication elsewhere), up to 15 pages in LNCS style, are invited through EasyChair.

  • 26 - 28 November 2020, 31st Novembertagung: Axiomatics: Ancient and Contemporary Perspectives, Berlin, Germany

    Date: 26 - 28 November 2020
    Location: Berlin, Germany
    Deadline: Wednesday 1 July 2020

    The Novembertagungis an international graduate conference on the history and philosophy of mathematics and neighbouring fields. It aims to provide an opportunity for graduate students at all levels to present and discuss their research in an informal and safe environment. It also allows young researchers to share experiences, get advice and establish new contacts.

    On the theme: While Euclid (c. 3rd century BC) is usually celebrated as the beginning of axiomatic science, many features that are nowadays taken to be essential to axiomatics appear to be alien to ancient mathematics. A major contemporary change in the view on axiomatics was initiated by the adoption of the set-theoretic axiomatic framework as a foundation of mathematics in the first half of the 20thcentury. Proof theory and model theory subsequently developed as independent research fields and had a wide impact on philosophical thought.On the other hand, some philosophers also argue that the axiomatic view on mathematics may be harmful in that it omits fundamental aspects of mathematical practice and idealizes mathematical reasoning in an unfaithful way.

    Abstracts should be in English, around 250-350 words, prepared for blind review, and submitted using the submission form on the website. Notifications will be sent out in August. Submissions by graduate student members of an underrepresented group in History of Mathematics or Philosophy of Mathematics are particularly encouraged.

    Note that the theme of axiomatics is meant to be a guideline and will not serve as an exclusionary factor for the selection of submissions.

  • 9 June 2020, 3rd International Workshop on User-Oriented Logic Paradigms (IULP 2020), Santiago de Compostela, Spain

    Date: Tuesday 9 June 2020
    Location: Santiago de Compostela, Spain

    The 3rd International Workshop of User-Oriented Logic Paradigms (IULP) focuses on discussing different aspects involved in making logic paradigms more user-friendly/oriented, where the "user" could be either an expert of the paradigm, or a non-expert who simply uses tools developed for the paradigm in some application. IULP aims to bring together researchers working on different logic paradigms, such as answer set programming, constraint logic programming, probabilistic logic programming, abductive logic programming, inductive logic programming, argumentation, principles of teaching etc., as user- friendliness is an important topic in all of these areas.

    IULP, collocated with the 24th European Conference on Artificial Intelligence (ECAI2020), aims to provide an international forum for researchers in the AI, KR, and applied sciences community to discuss and present advances in theories, formalisms, and applications to deliver the mature and well-defined methods of logic paradigms to a wider audience.

  • 14 - 19 June 2020, ICAPS 2020 Workshop on Epistemic Planning (EpiP 2020), to be rescheduled

    Date: 14 - 19 June 2020
    Location: Nancy, France

    Automated planning is of central concern in high-level symbolic AI research, with applications in logistics, robotics and service composition. In the simple case of an agent operating in a known world, the output of a planner is just a sequence of actions to be performed to the effect that it achieves a desired goal state. Epistemic planning is the enrichment of automated planning with epistemic notions, including knowledge and beliefs, which not only refer to incomplete knowledge, but also beliefs about this knowledge.

    Epistemic planning has promising application potentials in all types of domains requiring artificial agents that have skills both in planning and in reasoning about knowledge and beliefs (of themselves and others). Such applications include domestic robots interacting with humans, non-player characters in video games, and autonomous robots interacting in a factory setting. It is a relatively recent area of research, and is inherently multi-disciplinary involving research from automated planning, epistemic logic, and knowledge representation & reasoning. In order to achieve formalisms and systems for epistemic planning that are both expressive and practically efficient, it is necessary to combine the state of the art from all three areas.

    Due to the Corona crisis this conference will be rescheduled for fall 2020.

  • 15 - 19 June 2020, Caleidoscope: Research School in Computational Complexity, Paris, France

    Date: 15 - 19 June 2020
    Location: Paris, France

    Computational complexity theory was born more than 50 years ago when researchers started asking themselves what could be computed efficiently. Classifying problems/functions with respect to the amount of resources (e.g. time and/or space) needed to solve/compute them turned out to be an extremely difficult question. This has led researchers to develop a remarkable variety of approaches, employing different mathematical methods and theories.

    The future development of complexity theory will require a subtle understanding of the similarities, differences and limitations of the many current approaches. The goal (and peculiarity) of the Caleidoscope school is to reunite in a single event as many different takes on computational complexity as can reasonably be fit in one week. The school is aimed at graduate students and researchers who already work in some aspects of computational complexity and/or who would like to learn about the various approaches.

  • 17 - 19 June 2020, Workshop "Philosophy of Science meets Machine Learning", Tübingen, Germany

    Date: 17 - 19 June 2020
    Location: Tübingen, Germany

    Machine learning does not only transform businesses and the social sphere, it also fundamentally transforms science and scientific practice. The workshop focuses on that latter issue. It aims to discuss whether and how exactly recent developments in the field of machine learning potentially transform the process of scientific inquiry. For this, it sets out to analyse the field of machine learning through the lenses of philosophy of science, epistemology, research ethics and cognate fields such as sociology of science. The workshop will bring together philosophers from different backgrounds (from formal epistemology to the study of the social dimensions of science) and machine learning researchers.

    The workshop is organised by the 'Ethics and Philosophy Lab' of the Cluster of Excellence 'Machine Learning: New Perspectives for Science' at the University of Tübingen.

     

  • 20 - 21 June 2020, Hamburg Set Theory Workshop 2020 (HSTW 2020): Descriptive Set Theory, Forcing and the Reals, Hamburg, Germany

    Date: 20 - 21 June 2020
    Location: Hamburg, Germany

    Descriptive set theory discusses the relationship between logical complexity and good behaviour of sets, so-called regularity properties (e.g. Lebesgue measurability, perfect set property, etc.). It is well known that these properties are closely connected to forcing (and in some cases, large cardinals). Modern developments in set theory such as forcing, large cardinals and determinacy give powerful techniques to tackle problems in descriptive set theory. In recent years, set theorists have generalised classical results of descriptive set theory to generalised reals.

    Speakers: 1. Vera Fischer (Vienna) 2. Yurii Khomskii (Hamburg & Amsterdam) 3. Dominique Lecomte (Paris) 4. Heike Mildenberger (Freiburg) 5. Dorottya Sziraki (Budapest) 6. Otmar Spinas (Kiel) 7. Asger Tornquist (Copenhagen) 8. Jindrich Zapletal (Gainesville FL) more TBA.

  • 22 June - 4 July 2020, Seventh EPICENTER Spring Course in Epistemic Game Theory 2020, Maastricht University, Maastricht, The Netherlands

    Date: 22 June - 4 July 2020
    Location: Maastricht University, Maastricht, The Netherlands

    The EPICENTER, the research center on Epistemic Game Theory at Maastricht University, offers this two-week intensive course as an introduction to the blooming field of Epistemic Game Theory. This field takes a new, fresh approach to game theory, and studies how people reason in game theoretic situations before they eventually make a choice. More precisely, it explores how we reason about the minds of others before we make a choice. Hence, the reasoning of people like you and me is at the center stage of epistemic game theory.

    Date: 22 - 23 June 2020
    Location: Prague, Czech Republic

    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).

  • 29 June 2020, 9th International Workshop on Theorem Prover Components for Educational Software (ThEdu'20) , Proceedings only

    Date: Monday 29 June 2020
    Location: Paris, France

    Computer Theorem Proving is becoming a paradigm as well as a technological base for a new generation of educational software in science, technology, engineering and mathematics. The workshop was to bring together experts in automated deduction with experts in education in order to further clarify the shape of the new software generation and to discuss existing systems.

    The ThEdu'20 workshop was associated to IJCAR, which due to the COVID-19 crisis is now held as a Virtual Conference. It is our feeling that a virtual meeting might not allow us to fully reproduce the usual face-to-face networking opportunities of our event. So, unfortunately, the ThEdu'20 had better be cancelled.

    The interest expressed for the workshop was such, that the PC decided to publish proceedings, in spite of cancellation after IJCAR become virtual. Thanks to a decision of the EPTCS editorial board adapting to the specific situation, the proceedings already received the approval to be published by EPTCS.

  • 6 July 2020, ICALP/LICS Workshop "Decidable Fragments of First-order Modal Logic", Saarbruecken, Germany

    Date: Monday 6 July 2020
    Location: Saarbruecken, Germany

    First-order modal logic is a natural specification language for describing properties of many infinite-state systems, but it is notoriously undecidable, in the sense that even simple fragments (like the two-variable fragment) are undecidable. Despite this, in the recent few years, researchers have managed to find some useful syntactic restrictions that yield decidability. The workshop is intended as a review of this rapidly evolving direction of research. We seek to identify new potential techniques for constructing decision procedures.

  • 8 - 9 August 2020, Workshop on Semantic Spaces at the Intersection of NLP, Physics, & Cognitive Sciences (SemSpace2020), Utrecht, The Netherlands

    Date: 8 - 9 August 2020
    Location: Utrecht, The Netherlands

    Semantic Spaces at the Intersection of NLP, Physics, and Cognitive Science (SemSpace2020) 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.

    COVID-19 note: the workshop will take place, either in an online format or in person if the situation allows. Since ESSLLI 2020 (with which the workshop was originally to be co-located) has been cancelled, the dates and location may be subject to slight change.

  • 10 - 14 August 2020, Computational and Experimental Explanations in Semantics and Pragmatics

    Date: 10 - 14 August 2020
    Location: Utrecht

    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 explanation that can be offered.

    For example, experimental methods can help distinguish between alternative explanations of semantic effects, e.g. whether to classify controversial phenomena as implicatures or presuppositions. Similarly, computational models of semantics can generate fine-grained and non-categorical predictions that can fruitfully be tested experimentally. And both kinds of methods can be used to ask questions about the emergence of semantic structures in language, including which factors influence their distribution and typology.

    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.

  • 10 - 14 August 2020, ESSLLI-2020 Workshop "Approaches to Implicature", Utrecht, Netherlands

    Date: 10 - 14 August 2020
    Location: Utrecht, Netherlands

    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.

  • 29 - 30 August 2020, 8th Workshop "What can FCA do for AI?" (FCA4AI 2020), Santiago de Compostela, Spain

    Date: 29 - 30 August 2020
    Location: Santiago de Compostela, Spain

    Formal Concept Analysis (FCA) is a mathematically well-founded theory aimed at data analysis and classification. FCA allows one to build a concept lattice and a system of dependencies (implications and association rules) which can be used for many AI needs, e.g. knowledge processing, knowledge discovery, knowledge representation and reasoning, ontology engineering as well as information retrieval, recommendation, social network analysis and text processing. Recent years have been witnessing increased scientific activity around FCA, in particular a strand of work emerged that is aimed at extending the possibilities of plain FCA w.r.t. knowledge processing. While the capabilities of FCA are extended, new possibilities are arising in the framework of FCA.

    The 8th FCA4AI workshop, co-located with ECAI 2020, is (as usual) dedicated to discuss such issues, and in particular:
    - How can FCA support AI activities in knowledge discovery, knowledge representation and reasoning, machine learning, natural language processing...
    - By contrast, how the current developments in AI can be integrated within FCA to help AI researchers to solve complex problems in their domain.

    This workshop will aim to bring together researchers whose interests bridge between AI and other disciplines such as Cognitive Science, Language and Philosophy, to study how computational argumentation can form an underlying theoretical and practical basis for modeling cognition and building human-centric AI systems.
    The main general questions that will concern the workshop are:
    - Can argumentation provide the basis for computational models of human reasoning that are cognitively adequate?
    - How can we form a synthesis between computational argumentation and theories of cognition that will give us models of computational cognition for the development of AI systems?

  • 3 - 5 September 2020, Trends in Logic XX "Logic and Reasoning: Formal and Informal", Kyiv, Ukraine

    Date: 3 - 5 September 2020
    Location: Kyiv, Ukraine
    Target audience: Researchers in logic
    Costs: Conference fee: 160/190 EUR

    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).

    Location: Sofia, Bulgaria

    Mereology is a very plural subject in which individual researchers may work in multiple potentially incompatible perspectives. It is well-known that mereological methods are important in AI and formalizing human reasoning. In particular, these are relevant in formal approaches to vagueness and point-free reasoning. The main aim of the symposium session is to connect researchers in formal approaches to vagueness and ontology from applied mereological perspectives. All submissions are expected to have a strong focus on applications or potential applications.

    10 - 11 September 2020, Seventh International Workshop on Controlled Natural Language (CNL 2020)

    Date: 10 - 11 September 2020
    Location: Amsterdam
    Target audience: researchers and practitioners
    Costs: €200 (small changes are possible)

    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.

  • 11 - 12 September 2020, Mathematics & Analogical Reasoning, Munich, Germany

    Date: 11 - 12 September 2020
    Location: Munich, Germany

    Sometimes particular mathematical structures serve scientists as heuristic devices in their own right by giving indications of structural similarities between otherwise unrelated physical systems. And in philosophical discourse, it is often not singular mathematical formulas, but the entire structure of mathematics that is used as an argumentative point of reference. The goal of this conference is to investigate the role of mathematics as a heuristic device for analogical reasoning in science and philosophy.

  • 12 - 18 September 2020, 17th International Conference on Principles of Knowledge Representation and Reasoning (KR 2020), Rhodes, Greece

    Date: 12 - 18 September 2020
    Location: Rhodes, Greece

    Knowledge Representation and Reasoning (KRR) is an exciting, well-established field of research. In KRR 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. In recent years KRR has contributed to new and emerging fields including the semantic web, computational biology, and the development of software agents. The biennial International Conference on the Principles of Knowledge Representation and Reasoning (KR) is a leading forum for timely, in-depth presentation of progress in the theory and principles underlying the representation and computational management of knowledge.

  • 14 - 17 September 2020, 11th International Conference on Formal Ontology in Information Systems (FOIS 2020), Bolzano (Italy)

    Date: 14 - 17 September 2020
    Location: Bolzano (Italy)

    The advent of complex information systems that rely on robust, coherent and formal representations of their subject matter, has led to the exploitation of ontological analysis and ontology-based representation. The systematic study of such analysis and representation is at the center of the modern discipline of formal ontology, which is a general theory of the types of entities and relations making up domains of interest. Researchers in many domains engage with formal ontology to provide a solid foundation for their work.

    The FOIS conference is a meeting point for all researchers with an interest in formal ontology. FOIS 2020 includes a number of activities: FOIS conference (single track program), workshops (in conjunction with EKAW 2020 and ICBO 2020) ,tutorials (in conjunction with EKAW 2020 and ICBO 2020), a young researchers symposium, a demo and industry track, and an ontology show and tell. As in previous years, FOIS 2020 aims to be a nexus of interdisciplinary research and communication.

    Please note: FOIS will happen as a face-to-face event in Bolzano when it is safe to travel. Ideally, in September 2020 but otherwise at a later date in 2021.

  • 18 - 21 September 2020, 25th International Conference on Conceptual Structures (ICCS 2020), Bolzano, Italy

    Date: 18 - 21 September 2020
    Location: Bolzano, Italy

    The International Conferences on Conceptual Structures (ICCS) focus on the formal analysis and representation of conceptual knowledge, at the crossroads of artificial intelligence, human cognition, computational linguistics, and related areas of computer science and cognitive science. The ICCS conferences evolved from a series of seven annual workshops on conceptual graphs, starting with an informal gathering hosted by John F. Sowa in 1986. Recently, graph-based knowledge representation and reasoning (KRR) paradigms are getting more and more attention. With the rise of quasi-autonomous AI, graph-based representations provide a vehicle for making machine cognition explicit to its human users. This year ICCS 2020 is a part of 'Bolzano Summer of Knowledge' which will take place in Bolzano, Italy during the month of September, 2020.

  • 30 October - 1 November 2020, 2nd Tsinghua Interdisciplinary Workshop on Logic, Language, and Meaning, Beijing, China

    Date: 30 October - 1 November 2020
    Location: Beijing, China

    Monotonicity, in various forms, is a pervasive phenomenon in logic, linguistics, and related areas. In theoretical linguistics, monotonicity properties are relevant to a large array of semantic phenomena  and to the presence of pragmatic inferences such as scalar implicatures. In logic and mathematics, monotonicity guarantees the existence of fixed points and the well-formedness of inductive definitions. Also, monotonicity is closely tied to reasoning, in formal as well as natural languages. Recent logical and linguistic work on monotonicity has also found its way into computation systems for natural language processing and cognitive models of human reasoning. The goal of our workshop is to bring together researchers working on monotonicity or related properties, from different fields and perspectives.

    The first day of the workshop is devoted to two tutorials:
    1. Jakub Szymanik (University of Amsterdam): Monotonicity in Logic
    2. Gennaro Chierchia (Harvard University): Monotonicity in Language
    The remaining two days consist of invited and contributed talks.
