Calls for Paper

  • 29 June - 2 July 2021, 16th International Conference on Formal Concept Analysis (ICFCA 2021:16), Strasbourg, France

    Date: 29 June - 2 July 2021
    Location: Strasbourg, France
    Deadline: Monday 18 January 2021

    Formal Concept Analysis emerged in the 1980's from attempts to restructure lattice theory in order to promote better communication between lattice theorists and potential users of lattice theory. Since its early years, Formal Concept Analysis has developed into a research field in its own right with a thriving theoretical community and a rapidly expanding range of applications in information and knowledge processing including visualization, data analysis (mining) and knowledge management and discovery.

    The ICFCA conference series aims at bringing together researchers and practitioners working on theoretical or applied aspects of Formal Concept Analysis within major related areas such as Mathematics and Computer and Information Sciences and their diverse applications to fields like Software Engineering, Linguistics, Life and Social Sciences, etc.

    We invite scientific publications on theory and applications of Formal Concept Analysis. Papers of up to sixteen pages may be submitted in the PDF format via the Easychair system. Main topics of interest include, but are not limited to:
    - Fundamental aspects of FCA
    - Bridging FCA to information sciences and artificial intelligence
    - Understanding, modelling real-world data and phenomena with FCA

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

    Date: 9 - 13 August 2021
    Location: Utrecht
    Deadline: Monday 15 February 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 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.

    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

    We invite anonymized submission of abstracts of 2 pages (12 pt font; 1in or 2.5cm margins) — with an extra page for references of figures — on new research on topics related to those listed above by February 15.

  • 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.

  • 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.

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

    Date: 4 - 6 February 2021
    Location: Online

    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.

  • 12 - 14 May 2021, Trends in Logic XX "Logic and Reasoning: Formal and Informal", Kyiv, Ukraine

    Date: 12 - 14 May 2021
    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).

  • 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.

  • 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.

  • 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.

    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!

  • 12 - 18 September 2021, 5th International Autumn School "Proof and Computation" , Herrsching, Germany

    Date: 12 - 18 September 2021
    Location: Herrsching, Germany
    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 shifted to September 12-18, 2021.

  • 13 - 17 September 2021, Logic, Algebra and Truth Degrees 2020 (LATD 2020) , Tbilisi, Georgia

    Date: 13 - 17 September 2021
    Location: Tbilisi, Georgia

    This is one of the main events of the Tbilisi Autumn of Logic, a series of conferences and summer schools taking place in Tbilisi promoting research in pure and applied logic at an international level.

    The LATD conference series started as an official meeting of the working group on Mathematical Fuzzy Logic and has evolved into a wider meeting in algebraic logic and related areas. Its main goal is to foster collaboration between researchers in these areas, and to promote communication and cooperation with members of neighbouring fields.

    The conference will be preceded by the Sixteenth International Tbilisi Summer School in Logic and Language devoted to courses on core topics of LATD 2020.

    We regret to announce that due to the coronavirus pandemic LATD has been postponed to September 2021.

  • 13 - 16 September 2021, 11th International Conference on Formal Ontology in Information Systems (FOIS 2020), Bolzano (Italy)

    Date: 13 - 16 September 2021
    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.

    Unfortunately, because of the Corona situation we had to postpone FOIS XI by one year. Thus, the conference will occur in September 13-16, 2021 in Bozen.

  • 22 - 25 September 2021, 10th International Conference on Non-Classical Logics, Theory & Applications, Łódź, Poland

    Date: 22 - 25 September 2021
    Location: Łódź, Poland

    The Conference - devoted to non-classical logics - was initially held in Łódź in September 2008 and 2009. The conference serves as a forum to effectively exchange novel results and to survey works in widely understood non-classical logics and their applications.This year's tenth edition of the Conference will be an occasion to celebrate the 50th anniversary of the logic journal Bulletin of the Section of Logic, established in 1971.

    During this year's edition of the conference there will be a special session devoted to formal ontology, broadly conceived.

    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 2021.
