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.

After two years of successful work in the EU-MSCA-RISE project "Computing with Infinite Data" (CID) and two excellent Workshops CCC 2019 in Ljubljana (Slovenia) and CCC 2020 (online), we are planning to publish a collection of papers dedicated to the meetings, to the project and to the subject in general as a Special Issue in the open-access journal "Logical Methods in Computer Science" (LMCS).

The issue should reflect progress made in Computable Analysis and related areas, and is not restricted to work in the CID project or presented at the Workshop. Submissions are welcome from all scientists on topics in the entire spectrum from logic to algorithms. Editors: Daniel Graça (Faro, Portugal) and Alex Simpson (Ljubljana, Slovenia).

Hosted virtually at the University of Illinois at Urbana-Champaign The GSCL is a two-day conference organized by and for mathematical logic students in Master's and PhD programs.

ICALP is the main conference and annual meeting of the European Association for Theoretical Computer Science (EATCS). As usual, ICALP will be preceded by a series of workshops, which will take place on 12 July 2021.

We are closely monitoring the development of the COVID-19 pandemic. If it is not viable to hold ICALP 2021 as a physical conference, we will run it virtually on the same dates. We will decide in January 2021 at the latest.

The LMP Graduate Student Conference will bring together philosophers of logic, mathematics, and physics for two days of presentations and discussions with some of the leaders in these fields. We are pleased to announce our keynote speaker this year is James Owen Weatherall from the University of California, Irvine.

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.

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

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

The International Conference on Logic, Rationality and Interaction (LORI) conference series aims at bringing together researchers working on a wide variety of logic-related fields that concern the understanding of rationality and interaction. The series aims at fostering a view of Logic as an interdisciplinary endeavor, and supports the creation of an East-Asian community of interdisciplinary researchers.

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

The mission of the TARK conferences is to bring together researchers from a wide variety of fields, including Computer Science, Artificial Intelligence, Game Theory, Decision Theory, Philosophy, Logic, Linguistics, and Cognitive Science, in order to further our understanding of interdisciplinary issues involving reasoning about rationality and knowledge. Previous conferences have been held bi-annually around the world. Topics of interest: include, but are not limited to, semantic models for knowledge, belief, awareness and uncertainty, bounded rationality and resource-bounded reasoning, commonsense epistemic reasoning, epistemic logic, epistemic game theory, knowledge and action, applications of reasoning about knowledge and other mental states, belief revision, and foundations of multi-agent systems.

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.

The Panhellenic Logic Symposium is a biennial scientific event that was established in 1997. It aims to promote interaction and cross-fertilization among different areas of logic. Originally conceived as a way of bringing together the many logicians of Hellenic descent throughout the world, the PLS has evolved into an international forum for the communication of state-of-the-art advances in logic. The symposium is open to researchers worldwide who work in logic broadly conceived.

PLS13 will have Special Sessions on Computer Science and Philosophical Logic, as well as Tutorials, Invited and Contributed Talks, a Poster Session and a Mentoring Session.

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.

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 journal Linguistics and Philosophy (L&P) have agreed to publish a special issue of Super Linguistics. Super Linguistics subsumes the application of formal linguistic methodology and methodologies inspired by formal linguistics to diverse non-standard objects. In addition to manuscripts by linguists, we welcome submissions from all relevant fields (such as, but not limited to, biology and musicology) provided that they are super linguistic in nature. To be considered, the manuscript should include a short paragraph outlining in what way the research is super linguistic in nature and how the research advances this new sub-field. Submissions must propose a clear formal analysis based on rich and detailed data. The manuscript submission deadline for this special issue is April 23rd 2021.

The biennial ECSQARU conferences constitute a major forum for advances in the theory and practice of reasoning under uncertainty, with a focus on bringing symbolic and quantitative aspects together.

The scope of the ECSQARU conferences encompasses fundamental issues, applications, representation, inference, learning, and decision making in qualitative and numeric uncertainty paradigms.

The RAMiCS conference series has been the main venue for research on relation algebras, Kleene algebras and similar algebraic formalisms, and their applications as conceptual and methodologica tools in computer science and beyond.

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.

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.

The ERC Project SPAGAD: Speech Acts in Grammar and Discourse invites to a workshop on biased questions that focuses on (a) experimental results concerning the conditions of use of questions that express a bias towards particular answers, and (b) on the theoretical modelling of such questions that includes morphological markers, discourse particles, specialized syntactic structure, prosody and gestures.

AAMAS is the largest and most influential conference in the area of agents and multiagent systems, bringing together researchers and practitioners in all areas of agent technology and providing and internationally renowned high-profile forum for publishing and finding out about the latest developments in the field

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).

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.

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 2021.

CiE 2021 is the seventeenth conference organized by the Association Computability in Europe.

The Logic Colloquium is the European Summer Meeting of the Association for Symbolic Logic, an international organization supporting research and critical studies in logic. Its primary function is to provide an effective forum for the presentation, publication, and critical discussion of scholarly work in this area of inquiry.

The program will feature tutorials by Krzysztof Krupiński (University of Wrocław) and Andrew Marks – (University of California, Los Angeles), and special sessions on Set Theory, Model Theory, Modal and Epistemic Logic, Proofs and Programs, Computability Logic, and Cognitive Science and Linguistics.

Due to public health concerns regarding COVID-19, the ASL Executive Committee, in consultation with the local organizers and the ASL European Committee, has made the decision to postpone the 2020 Logic Colloquium. It will take place on July 19-24, 2021, approximately a year later than originally scheduled, in the same location: Poznan, Poland.

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

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

The circumstances around the coronavirus (COVID-19) pandemic forced the organizers to postpone the 32nd edition of ESSLLI, planned for 2020 in Utrecht as ESSLLI-2020, to 2-13 august 2021.

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.

Due to the unclear situation regarding COVID-19 and the reluctance of some colleagues to attend any events in August or September, and after discussing several options with the Steering Committee, we have decided to postpone the conference to 2021, likely to the first days of August 2021.

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.

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.

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.

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!

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.

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.

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.

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.
