  • 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.

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

    Date: 6 - 8 December 2021
    Location: Bochum, Germany
    Deadline: Tuesday 31 August 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.

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

    Date: 23 - 26 November 2021
    Location: Bochum, Germany
    Deadline: Wednesday 1 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.

     

    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).

  • 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).

    For more information, see https://www.springer.com/journal/11245/updates/18364346 or contact Paola Cantù at , or Italo Testa at .
  • CfP Special Issue of Annals of Pure and Applied Logic (APAL) on “Combining Probability and Logic”

    Deadline: Friday 31 December 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.

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

    Date: 26 - 31 July 2021
    Location: Virtual

    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.

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

    Date: 9 - 13 August 2021
    Location: Online via Zoom

    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.

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

    Date: 9 - 10 August 2021
    Location: Online

    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.

  • 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.

    Date: 8 - 10 September 2021
    Location: Virtual

    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.

    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!

    Date: 11 - 18 September 2021
    Location: Bolzano (Italy) & Virtual

    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.

  • 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)

    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.

  • 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.

  • 6 - 8 November 2021, Second Workshop on Second-Order Quantifier Elimination and Related Topics (SOQE 2021), Virtual

    Date: 6 - 8 November 2021
    Location: Virtual

    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).

  • 6 - 8 November 2021, 2nd Workshop on Explainable Logic-Based Knowledge Representation (XLoKR 2021) , Hanoi, Vietnam (Virtually)

    Date: 6 - 8 November 2021
    Location: Hanoi, Vietnam (Virtually)

    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.

  • 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

    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.

  • 5 - 17 July 2022, Seventh EPICENTER Spring Course in Epistemic Game Theory 2020, Maastricht University, Maastricht, The Netherlands

    Date: 2022
    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.

    Due to the Corona-outbreak, the edition of 2020 had to be cancelled. The next edition will be in 2022.
