Calls for Paper

  • 6 - 9 September 2021, Twenty-fourth International Conference on Text, Speech and Dialogue (TSD2021), Olomouc (Czech Republic) or Virtual

    Date: 6 - 9 September 2021
    Location: Olomouc (Czech Republic) or Virtual
    Deadline: Sunday 18 April 2021

    The TSD series evolved as a prime forum for interaction between researchers in both spoken and written language processing from all over the world.  The conference program will include presentation of invited papers (keynote speeches), oral presentations, and poster/demonstration sessions. Papers will be presented in plenary or topic oriented sessions.

    TSD2021 is going to take place in the beautiful city of Olomouc, Czech Republic. Thus, it is nicely colocated with Interspeech 2021 which is going to be held in Brno, Czech Republic. But as the situation in September 2021 cannot be easily predicted, the TSD2021 organizing committee is ready to organize a virtual conference, if necessary.

    The organizing committee invites papers to be presented during the conference, as well as proposals for workshops and demonstrations. Topics of the conference will include (but are not limited to): Corpora and Language Resources, Speech Recognition, Tagging, Classification and Parsing of Text and Speech, Speech and Spoken Language Generation, Semantic Processing of Text and Speech, Integrating Applications of Text and Speech Processing, Automatic Dialogue Systems , and Multimodal Techniques and Modelling. Papers on processing of languages other than English are strongly encouraged.

    Date: 6 - 9 September 2021
    Location: Birmingham (UK) and Virtual
    Deadline: Monday 19 April 2021

    TABLEAUX is the main international conference at which research on all aspects -- theoretical foundations, implementation techniques, systems development and applications -- of tableaux-based reasoning and related methods is presented.

    TABLEAUX 2021 will be co-located with the 13th International Symposium on Frontiers of Combining Systems (FroCoS 2021). The conferences will provide a rich programme of workshops, tutorials, invited talks, paper presentations and system descriptions.

    Submissions are invited in the following two categories: (A) research papers reporting original theoretical research or applications, with length up to 15 pages excluding references; (B) system descriptions, with length up to 9 pages excluding references.

    Topics of interest include but are not limited to:
    * tableau methods for classical and non-classical logics (including first-order, higher-order, modal, temporal, description, hybrid, intuitionistic, linear, substructural, fuzzy, relevance and non-monotonic logics) and their proof-theoretic foundations;
    * sequent, natural deduction, labelled, nested and deep calculi for classical and non-classical logics, as tools for proof search and proof representation;
    * related methods (SMT, model elimination, model checking, connection methods, resolution, BDDs, translation approaches);
    * flexible, easily extendable, light-weight methods for theorem proving; novel types of calculi for theorem proving and verification in classical and non-classical logics;
    * systems, tools, implementations, empirical evaluations and applications (provers, proof assistants, logical frameworks, model checkers, etc.);
    * implementation techniques (data structures, efficient algorithms, performance measurement, extensibility, etc.);
    * extensions of tableau procedures with conflict-driven learning;
    * techniques for proof generation and compact (or humanly readable) proof representation;
    * theoretical and practical aspects of decision procedures;
    * applications of automated deduction to mathematics, software development, verification, deductive and temporal databases, knowledge representation, ontologies, fault diagnosis or teaching.

    We also welcome papers describing applications of tableau procedures to real-world examples. Such papers should be tailored to the TABLEAUX community and should focus on the role of reasoning and on logical aspects of the solution.

  • (New) 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.

  • 13 - 16 September 2021, 12th International Conference on Formal Ontology in Information Systems (FOIS 2021), Bolzano (Italy) and Virtual

    Date: 13 - 16 September 2021
    Location: Bolzano (Italy) and Virtual
    Deadline: Thursday 22 April 2021

    The FOIS conference is a meeting point for all researchers with an interest in formal ontology. Formal ontology is the systematic study of the types of entities and relations making up the domains of interest represented in modern information systems. FOIS is the flagship conference of the International Association for Ontology and its Applications (IAOA) and aims to be a nexus of interdisciplinary research and communication, inclusive of researchers from many domains engaging with formal ontology.

    FOIS 2021 is planned as a hybrid event: there will be a physical meeting in Bozen-Bolzano, Italy, with a remote participation option. FOIS 2021 includes a number of activities: FOIS conference (single track program), workshops, tutorials, an early-career symposium, a demo and industry track, and an ontology show and tell.

    FOIS 2021 seeks three types of full-length (14 page) high-quality papers on a wide range of topics: Foundational papers (addressing content-related ontological issues, their formal representation, and their relevance to some aspect of information systems), Application papers (addressing novel methods and systems related to building, evaluating, or using ontologies, emphasizing the impact of ontology contents on the application) and Domain ontology papers (describing a novel ontology for a specific realm of interest, clarifying ontological choices against requirements and foundational theory, and showing ontology use).

    Related activities, such as workshops and tutorials, may specify different submission formats, for example, short papers or posters.

  • (Updated) 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.

  • (New) 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.

    Deadline: Saturday 15 May 2021

    CiE 2021 is the seventeenth conference organized by the Association Computability in Europe. The 'Computability in Europe' conference (CiE) series has built up a strong tradition for developing a scientific program which is interdisciplinary at its core bringing together all aspects of computability and foundations of computer science, as well as the interplay of these theoretical areas with practical issues in CS and other disciplines such as biology, mathematics, history, philosophy, and physics.

    Due to the current pandemic CiE 2021 will be held as a virtual conference. CiE 2021 will be the second CiE conference that is organized as a virtual event and aims at a high-quality meeting that allows and invites active participation from all participants. It will be hosted virtually by Ghent University.

    The Programme Committee cordially invites all researchers (European and non-European) to submit their papers in computability related areas for presentation at the conference and inclusion in the proceedings. Papers building bridges between different parts of the research community are particularly welcome. Papers should be in English and anonymized. They must be submitted in PDF format, using the LNCS style and should have a maximum of 10 pages. Deadline: 17 jan 2021.

    Continuing the tradition of past CiE conferences, in addition to the formal presentations based on the LNCS proceedings volume, CiE 2021 will host a track of informal presentations, that are prepared very shortly before the conference and inform the participants about current research and work in progress. The deadline for the submission of abstracts for informal presentations is May 15th, 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.

  • 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.

  • (New) 22 April 2021, KNAW-webinar: De logica van AI

    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.

  • 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

    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.

  • 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

    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.

  • 24 - 28 May 2021, Thirteenth NASA Formal Methods Symposium (NFM 2021), Virtual and Norfolk VA, U.S.A.

    Date: 24 - 28 May 2021
    Location: Virtual and Norfolk VA, U.S.A.

    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.

    The symposium will be held in an in-person/virtual hybrid format in Norfolk, VA, USA, possibly transitioning to fully virtual depending on the COVID-19 situation.

  • (Updated) 26 May 2021, First ENCODE Workshop "Let's Talk Models!", Rotterdam, The Netherlands or Virtual

    Date & Time: Wednesday 26 May 2021, 09:00-17:00
    Location: Rotterdam, The Netherlands or Virtual

    "Let's Talk Models!" is the kick-off workshop for the NWO VIDI project ENCODE: Explicating Norms of Collective Deliberation. As part of this project, we will organize workshops on a regular basis at the EIPE/ESPhil (Erasmus University of Rotterdam).

    The theme of this edition is Formal Models of Deliberative Norms. In particular, a range of different models (logical, agent-based, game-theoretic and/or argument-based) of group deliberation and its norms will be presented and discussed. The ultimate aim is to understand how these models shed light on trade-offs and tensions among such norms, and on different recipes for checking and monitoring their satisfaction.

    The conference takes place online via Zoom. Confirmed speakers are Hun Chung (Waseda University), Erica Yu (Erasmus University of Rotterdam), Olivier Roy (University of Bayreuth) and Soroush Rafiee Rad (University of Bayreuth & University of Amsterdam), and Nina Gierasimczuk (Danish Technical University). The full programme, incl. titles and abstracts of the talks can be found at

  • 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.

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

    Date: 14 - 18 June 2021
    Location: Online, Netherlands

    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.

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

    Date: 14 - 18 June 2021
    Location: Virtual

    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.

  • 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

    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.

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

    Date: Sunday 18 July 2021
    Location: Virtual

    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.

  • 1 - 4 August 2021, Spatial Cognition 2020/1 (SC 2020/1), Riga, Latvia

    Date: 1 - 4 August 2021
    Location: Riga, Latvia

    Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation. SC 2020 will bring together researchers working on spatial cognition from all of these perspectives.

    The conference is single-track, and the final program will be the result of a selective review process. The program will include oral and poster presentations of refereed papers, and keynote talks by Sara I. Fabrikant, Steve Franconeri and Laure Rondi-Reig.

    The initial conference was scheduled August 2020; this is the postponed version of it; the organizers are carefully observing the circumstances and will be hosting a virtual or a hybrid conference (with some talks in physical co-presence and some – virtually).

  • 9 - 13 August 2021, Computational and Experimental Explanations in Semantics and Pragmatics

    Date: 9 - 13 August 2021
    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.

  • 9 - 13 August 2021, ESSLLI-2021 Workshop "Approaches to Implicature", Utrecht, Netherlands

    Date: 9 - 13 August 2021
    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.

  • 10 - 14 August 2021, ESSLLI Workshop "Computing Semantics with Types, Frames, & Related Structures", Utrecht, The Netherlands

    Date: 10 - 14 August 2021
    Location: Utrecht, The Netherlands

    The goal of this workshop is to bring together people interested in structured representations of semantic information, especially from a computational perspective. In recent years, there has been a growing body of research which aims to integrate structured entities into formal semantic accounts. Important developments in this direction are the introduction of rich type systems and the use of frame-based representations, among others. The workshop is open to both foundational issues of structured semantic representations and applications to specific linguistic phenomena.

    A first edition of the workshop took place in Gothenburg as part of IWCS 2019.

  • 27 - 28 August 2021, Mathematics & Analogical Reasoning, Munich, Germany

    Date: 27 - 28 August 2021
    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.

    The conference has been postponed to 2021 due to the COVID-19 epidemic.

  • 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

    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.

  • 5 - 8 September 2021, Logic @ DGPhil, Erlangen, Germany

    Date: 5 - 8 September 2021
    Location: Erlangen, Germany

    There will be a section on Logic and Philosophy of Mathematics at the XXVth Congress of the German Society for Philosophy (DGPhil), "The True, the Good, and the Beautiful".

    Unfortunately, due to the current Covid-19 pandemic it is impossible to hold our congress as planned (6th – 9th September 2020). It is not yet clear whether it would even be legally possible to hold it this year. However, it is clear that it would require very severe restrictions, so that essential goals of the congress could not be achieved. The congress is therefore postponed by one year.

    9 - 10 September 2021, Seventh International Workshop on Controlled Natural Language (CNL 2020)

    Date: 9 - 10 September 2021
    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.

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

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

    Date: 6 - 12 November 2021
    Location: Hanoi, Vietnam

    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.
