FG 2020 is the 25th conference on Formal Grammar, to be held in conjunction with the European Summer School in Logic, Language and Information which, in 2020, will take place at the University of Utrecht, Utrecht, the Netherlands.

FG provides a forum for the presentation of new and original research on formal grammar, mathematical linguistics and the application of formal and mathematical methods to the study of natural language. Previous conferences in this series have welcomed papers from a wide variety of frameworks. The program will include a special session on the relevance of formal grammar methods in deep learning and other statistical and vector space approaches to language.

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.

The European Summer School in Logic, Language and Information (ESSLLI) is an annual event under the auspices of the Association for Logic, Language and Information (FoLLI) and brings together logicians, linguists, computer scientists, and philosophers to study language, logic, and information, and their interconnections.

The ESSLLI Student Session is a forum for PhD and Master students to present their research at the interfaces of logic, language and computation. It features three tracks: Logic & Computation (LoCo), Logic & Language (LoLa), and Language & Computation (LaCo). The ESSLLI 2020 Student Session will be held during ESSLLI 2020 at Utrecht University, Utrecht, the Netherlands

We invite participatuib in the XXIII International Summer School in Philosophy of Physics to be held in Urbino 15th-18th June 2020. The topic of the school is 'Philosophy of Quantum Computation' and it will feature lectures given by Michael Cuffaro (Munich Center for Mathematical Philosophy) and Roberto Giuntini (University of Cagliari), with afternoon seminars given by David Vitali (University of Macerata), Gustavo Martin Bosyk (University of Cagliari), and Rossella Lupacchini (University of Bologna). The School will host a limited number of students, graduate students and early researchers depending on a successful application.

Logical frameworks and meta-languages form a common substrate for representing, implementing and reasoning about a wide variety of deductive systems of interest in logic and computer science. Their design, implementation and their use in reasoning tasks, ranging from the correctness of software to the properties of formal systems, have been the focus of considerable research over the last two decades. This workshop will bring together designers, implementors and practitioners to discuss various aspects impinging on the structure and utility of logical frameworks, including the treatment of variable binding, inductive and co-inductive reasoning techniques and the expressiveness and lucidity of the reasoning process.

LFMTP 2020 is affiliated with FSCD 2020 and IJCAR 2020. To celebrate the 60th birthday of Frank Pfenning and his great many contributions to the topics of LFMTP, one session will be devoted to talks by collaborators and friends of Frank.

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, oral presentations, and poster/demonstration sessions. Papers will be presented in plenary or topic oriented sessions with sufficient time for discussions of the issues raised.The TSD 2020 conference will be accompanied by one-day satellite workshops or project meetings with organizational support by the TSD organizing committee. Social events including a trip in the vicinity of Brno will allow for additional informal interactions.

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

ThEdu'20 is part of "Paris Nord Summer of LoVe 2020". Invited Talk: Gilles Dowek, ENS Paris-Saclay.

Unification is concerned with the problem of making two terms equal, finding solutions for equations or making formulas equivalent. It is a fundamental process used in a number of fields of computer science, including automated reasoning, term rewriting, logic programming, natural language processing, program analysis, types, etc.  The International Workshop on Unification (UNIF) is a yearly forum for researchers in unification theory and related fields to meet old and new colleagues, to present recent (even unfinished) work, and to discuss new ideas and trends. It is also a good opportunity for young researchers and scientists working in related areas to get an overview of the state of the art in unification theory.

The 34th International Workshop on Unification is part of "Paris Nord Summer of LoVe 2020", a joint event on LOgic and VErification at Universit́e Paris 13. UNIF 2020 will be a satellite workshop of The International Joint Conference on Automated Reasoning (IJCAR 2020).

WoLLIC is an annual international forum on inter-disciplinary research involving formal logic, computing and programming theory, and natural language and reasoning. Each meeting includes invited talks and tutorials as well as contributed papers. WoLLIC 2020 is planned to also have a special session with the exhibition of a one-hour documentary film about Maryam Mirzakhani, a remarkable mathematician whose contributions were recognized with a Fields Medal just a few years before her untimely death.

CLIB covers a broad spectrum of areas related to natural language processing and computational linguistics focused on but not limited to Bulgarian.

CLIB 2020's invited speakers will be: Prof. Galya Angelova (Institute of Information and Communication Technologies, Bulgarian Academy of Sciences Assoc), Prof. Svetla Boytcheva (Institute of Information and Communication Technologies, Bulgarian Academy of Sciences) and Dr. Preslav Nakov (Qatar Computing Research Institut). A special session on wordnets and ontologies is also envisaged.

In light of the COVID-19 pandemic and its impact on everyone's life, we feel that the responsible thing to do is to postpone the conference until better times. Given the rapid unfolding of events, the exact dates for CLIB 2020 will be announced at a later point, but we are looking forward to reschedule the conference for late September 2020 and will be working hard to make this happen.

As it is its tradition, *AUTOMATA 2020* will focus on the theory and application of cellular automata and discrete dynamical systems in connection to complexity theory and algorithmic information. There will be special sessions on *Automata in Deep Learning* and *Algorithmic Information Dynamics* with a particular interest in aspects of computability in causation and reprogrammability.

AUTOMATA 2020 is innovating on various fronts given the challenge of climate change we want to reduce the conference Carbon footprint through a virtual attendance option, and also by addressing the underrepresentation of young and minority groups in the field.

Exploiting the common ground provided by vector spaces, the proposed workshop will bring together researchers working at the intersection of NLP, cognitive science, and physics, offering to them an appropriate forum for presenting their uniquely motivated work and ideas. The interplay between these 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.

SemSpace2020 will be co-located with ESSLLI 2020. Additionally, we will have a special session on the relevance of formal grammar methods in deep learning and other statistical and vector space approaches to language.  This session is organised jointly with the Formal Grammar conference.

NAtural LOgic Meets MAchine Learning (NALOMA) is the first workshop of its kind, aiming to bridge the gap between Machine Learning and Natural Logic. It will take place from July 11-July 17, 2020, during the 9th North American Summer School for Logic, Language, and Information (NASSLLI) at Brandeis University in Waltham, Massachusetts. The aim of this workshop is to bring together researchers working in both Natural Logic and Machine Learning approaches to NLI, initiating a discussion with the two sets of researchers that have been largely unconnected up to now.

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 Women in Logic workshop (WiL) provides an opportunity to increase awareness of the valuable contributions made by women in the area of logic in computer science. Its main purpose is to promote the excellent research done by women, with the ultimate goal of increasing their visibility and representation in the community. Women in Logic 2020 is part of "Paris Nord Summer of LoVe 2020", a joint event on LOgic and VErification at Universit́e Paris 13, made of Petri Nets 2020, IJCAR 2020, FSCD 2020, and over 20 satellite events.

Our aim is to:
- provide a platform for female researchers to share their work and achievements;
- increase the feelings of community and belonging, especially among junior faculty, post-docs and students through positive interactions with peers and more established faculty;
- establish new connections and collaborations;
- foster a welcoming culture of mutual support and growth within the logic research community.
We believe these aspects will benefit women working in logic and computer science, particularly early-career researchers.

Thanks to the generous support of SIGLOG, the Vienna Center for Logic and Algorithms (VCLA) and the Institute of Logic, Language and Computation of the University of Amsterdam (ILLC), applications for awards are invited to facilitate students and postdocs, who are authors of accepted papers to register and travel to the WiL 2020. Deadline: May 15, 2020. The awardees of the SIGLOG/VCLA/ILLC Travel Award will be reimbursed for a portion of their travel expenses, and registration costs. There will be at most one award per paper.

The aim of this Joint Linearity and TLLA workshop is to bring together researchers who are currently working on linear logic and related fields, to foster their interaction and provide a forum for presenting new ideas and work in progress. We also hope to enable newcomers to learn about current activities in this area. New results that make central use of linearity, ranging from foundational work to applications in any field, are welcome. Also welcome are more exploratory presentations, which may examine open questions and raise fundamental concerns about existing theories and practices.

Conference on Theory and Applications of Satisfiability Testing (SAT).

"Concepts in Action: Representation, Learning, and Application" (CARLA) is an international workshop aimed at fostering interdisciplinary exchange about research on concepts.  Although the workshop is open for research on any aspect of concepts, there exists a set of core topics that are of special interest:

 - Representation: How can we formally describe and model concepts?
  - Learning: Where do concepts come from and how are they acquired?
 - Application: How are concepts used in cognitive tasks?

Invited Speakers: Mattis List and Marianna Bolognesi.

This bi-annual conference  focuses on all aspects of grammar learning, including (but not limited to) theoretical and experimental analysis of different models of grammar induction, and algorithms for induction of different classes of languages and automata.

This edition will provide a particular insight  on the relation with connectionist models such as neural networks: tutorials of the first day will focus on that subject and authors are encouraged to submit works on that subject.

The International Joint Conference on Rules and Reasoning (RuleML+RR) is the leading international joint conference in the field of rule-based reasoning. Stemming from the synergy between the well-known RuleML and RR events, one of the main goals of this conference is to build bridges between academia and industry.

RuleML+RR 2020 aims to bring together rigorous researchers and inventive practitioners, interested in the foundations and applications of rules and reasoning in academia, industry, engineering, business, finance, healthcare and other application areas. It provides a forum for stimulating cooperation and cross-fertilization between the many different communities focused on the research, development and applications of rule-based systems.

RuleML+RR 2020 is co-located with DecisionCAMP 2020 and the 16th Reasoning Web Summer School (RW 2020), as part of the Declarative AI 2020 event. The theme of the 2020 edition is: Explainable algorithmic decision-making

The triennial international conference of the Italian Society for Logic and the Philosophy of Science, will be held at the Department of Philosophy and Communication of the University of Bologna.

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.

Since the first conference held in Marseille in 1982, the International Conference on Logic Programming (ICLP 2020) has been the premier international event for presenting research in logic programming.

Contributions are solicited in all areas of logic programming, including but not restricted to Foundations, Declarative Programming, Related Paradigms and Synergies, Implementation and Applications. Besides the main track, ICLP 2020 will host an Applications Track, a Sister Conferences and Journal Presentation Track, a Special Session on Women in Logic Programming, and a Research Challenges in Logic Programming Track. In addition to the presentations of accepted papers, the technical program will include invited talks, advanced tutorials, the doctoral consortium, and several workshops. A school on logic programming will be held before the conference.

SetVR 2020 will be the 7th meeting, with the first one held in 2004, previously called the Euler Diagrams Workshop. It aims to promote theoretical, empirical, applied research on visualization and diagrammatic reasoning, especially, about sets (set-theoretical and grouped data). SetVR 2020 will run as part of Diagrams 2020 conference, which will be held from August 24th to 28th in 2020, and is expected to occupy one day during this period.

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

On Monday-Tuesday September 28-29, 2020, the UCLA Philosophy department will host a workshop entitled "Logic and Formal Methods in Philosophy." We are delighted to announce the following invited speakers:

Talks: James Cummings (Carnegie Mellon University) Péter Komjáth (Eötvös Loránd University) Menachem Magidor (The Hebrew University of Jerusalem) * Itay Neeman (UCLA) * Assaf Rinot (Bar-Ilan University) Jouko Väänänen (University of Helsinki) * To confirm

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

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

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.

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.

NMR is the premier forum for results in the area of nonmonotonic reasoning. Its aim is to bring together active researchers in this broad field within knowledge representation and reasoning (KRR), including belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, argumentation, causality, and many other related topics including systems and applications.

As in previous editions, NMR 2020 aims to foster connections between the different subareas of nonmonotonic reasoning and provide a forum for emerging topics. Workshop activities will include invited talks and presentations of technical papers. NMR 2020 is co-located with the International Conference on Principles of Knowledge Representation and Reasoning (KR 2020) and the 33rd International Workshop on Description Logics (DL 2020). In particular, NMR 2020 will share a joint session with DL 2020.

The aim of GandALF 2020 is to bring together researchers from academia and industry which are actively working in the fields of Games, Automata, Logics, and Formal Verification. The idea is to cover an ample spectrum of themes, ranging from theory to applications, and stimulate cross-fertilisation.

This year, GANDALF will be organised together with a workshop on Stochastic Games organised by the GAMENET network which will held on September 23-24, 2020. The GAMENET meeting will focus on stochastic games with applications in computer science, economy and mathematics.

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

Invited Speakers: Johan van Benthem

Arguments vary in strength. The strength of an argument is affected by e.g. the plausibility of its premises, the nature of the link between its premises and conclusion, and the prior acceptability of the conclusion. The aim of this workshop is to bring together experts from the fields of artificial intelligence, philosophy, logic, and argumentation theory to discuss questions related to the strength of arguments.

Keynote speakers: Ofer Arieli (The Academic College of Tel-Aviv, Israel) Elise Bonzon (Paris Descartes University, France) Sanjay Modgil (King's College London, England) Wolfgang Spohn (University Konstanz, Germany) Serena Villata (I3S research centre in Sophia Antipolis, France).

The journal "Logical Investigations" provides a platform for broad discussions of logical problems of both conceptual and purely theoretical nature. There are plans for a special issue of "Logical Investigations" devoted to logical and philosophical aspects of negation, Vol. 27(1), 2021.

Original papers are invited on negation related topics. Submissions should be written in English and should be submitted electronically as Pdf-documents generated from LaTeX using the style file LIarticle.cls. Papers should not exceed 20 pages in the above mentioned format (including all notes, the bibliography, and the abstract).

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.

ICDT is an international conferences series that addresses the principles and theory of data management. Since 2009, it is annually and jointly held with EDBT, the international conference on extending database technology.

As ICDT strives to broaden its scope, ICDT 2020 will have a Reach Out Track that calls for novel formal frameworks or directions for database theory and/or connections between principles of data management and other communities.

Due to the current situation regarding the Coronavirus, the physical meeting for EDBT/ICDT 2020 in Copenhagen has to be canceled. However, EDBT/ICDT 2020 as a conference is NOT canceled, but will be held as an online event.

Argumentation and exchange of information help groups to coordinate, deliberate and decide. On the other hand, debates often generate detrimental large-scale phenomena such as polarization, informational cascades and echo-chambers, where the behavior of entire groups shifts in seemingly irrational ways.

Understanding the deep mechanisms of informational and social influence that underlie these phenomena in the age of social media is a challenge that engages methods from different disciplines, including philosophy, artificial intelligence, computer and social sciences and psychology.

This workshop brings together scholars with different theoretical approaches. Its broader aim is to foster an interdisciplinary understanding of the mechanisms that determine the behavior of individuals in a social context from multiple perspectives. The workshop will last two and a half days. The first half-day of it will be dedicated to an introductory seminar on abstract argumentation, held by Professor Pietro Baroni (Brescia).

Due to the spreading of COVID-19, this workshop will be held online as a video-conference-only.

Cancelled due to Corona, to be rescheduled.

EvoStar comprises of four co-located conferences run each spring at different locations throughout Europe. These events arose out of workshops originally developed by EvoNet, the Network of Excellence in Evolutionary Computing, established by the Information Societies Technology Programme of the European Commission, and they represent a continuity of research collaboration stretching back over 20 years. EvoStar is organised by SPECIES, the Society for the Promotion of Evolutionary Computation in Europe and its Surroundings. This non-profit academic society is committed to promoting evolutionary algorithmic thinking, with the inspiration of parallel algorithms derived from natural processes. It provides a forum for information and exchange.

The four conferences include:
 - EuroGP 23rd European Conference on Genetic Programming
 - EvoApplications 23rd European Conference on the Applications of Evolutionary and bio-inspired Computation
 - EvoCOP 20th European Conference on Evolutionary Computation in Combinatorial Optimisation
 - EvoMUSART 9th International Conference (and 14th European event) on Computational Intelligence in Music, Sound, Art and Design

This conference has been cancelled due to the Corona crisis.

There has been a recent move in philosophy of science towards views that in some sense reject the strict dichotomy between realism and anti-realism, or otherwise situate themselves between these two extremes. These include varieties of structuralism, perspectivalism, and pluralism/relativism, and have been applied across various scientific domains, including physics, mathematics, biology, cognitive science, and computer science. This conference will bring together representatives of each of these viewpoints, in order to compare the respective progress made by each approach, and to develop a shared foundation for the future development of alternatives to traditional scientific realism and anti-realism.

Confirmed Keynote Speakers: James Ladyman (Bristol), Michela Massimi, (Edinburgh) and Martin Kusch (Vienna).

In more than a decade of research, it has been established that a wide variety of state-based dynamical systems, like transition systems, automata (including weighted and probabilistic variants), Markov chains, and game-based systems, can be treated uniformly as coalgebras. Coalgebra has developed into a field of its own interest presenting a deep mathematical foundation, a growing field of applications, and interactions with various other fields. Established in 1998, the aim of the CMCS workshops is to bring together researchers with a common interest in the theory of coalgebras, their logics, and their applications. As the workshop serie strives to maintain breadth in its scope, participation by researchers in neighbouring areas is strongly encouraged.

Today's IT systems, and the interactions between them, become increasingly complex. Power grid blackouts, airplane crashes, failures of medical devices and malfunctioning automotive systems are just a few examples of incidents that affect system safety. They are often due to component failures and unexpected interactions of subsystems under conditions that have not been anticipated during system design and testing. Determining the root cause(s) of a system-level failure and elucidating the exact scenario that led to the failure is today a complex and tedious task that requires significant expertise. Formal approaches for automated causality analysis, fault localization, explanation of events, accountability and blaming have been proposed independently by several communities - in particular, AI, concurrency, model-based diagnosis, software engineering, security engineering and formal methods. Work on these topics has significantly gained speed during the last years.

The goals of this workshop are to bring together and foster exchange between researchers from the different communities, and to present and discuss recent advances and new ideas in the field.

Logic programming is a framework for expressing programs, propositions and relations as Horn clause theories, with the purpose of performing automatic inference in these theories. The aim of this workshop is to bring together researchers that work on extensions of logic programming and inference methods, and to foster an exchange of methods and applications that have emerged in different communities.

This workshop aims to bring together researchers working in the communities of Constraint/Logic Programming (e.g., ICLP and CP), Program Verification (e.g., CAV, TACAS, and VMCAI), and Automated Deduction (e.g., CADE), on the topic of Horn clause based analysis, verification and synthesis. Horn clauses have been advocated by these communities at different times and from different perspectives, and this workshop is organized to stimulate interaction and a fruitful exchange and integration of experiences.

The widespread use and increasing complexity of mission-critical and safety-critical systems at NASA and the aerospace industry requires advanced techniques that address their specification, design, verification, validation, and certification requirements. The NASA Formal Methods Symposium is a forum to foster collaboration between theoreticians and practitioners from NASA, academia, and industry, with the goal of identifying challenges and providing solutions towards achieving assurance for such critical systems.

New developments and emerging applications like autonomous on-board 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. The focus of these symposiums are 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.

ISA-16 is the sixteenth edition of a series of joint workshops of the ACL Special Interest Group in Semantics (SIGSEM) and the International Organisation for Standardisation ISO. ISA-workshops bring together experts in the annotation of semantic information as expressed in text, speech, gestures, graphics, video, images, and in communicative behaviour where multiple modalities are combined. Examples of semantic annotation include the markup of events, time, space, dialogue acts, discourse relations, semantic roles, coreference, quantification phenomena, and other aspects of meaning for which the ISO organisation pursues the establishment and application of standardised annotation methods and representation schemes, in order to support the creation of interoperable semantic and pragmatic resources.

Besides a main track, ISA-16 will feature two specialised tracks, focused on (a) the annotation of quantification (and quantified modification) in natural language and (b) the design and representation of data structures for generating visualisations of linguistically represented objects, properties, and events. Both specialised tracks will consist of a pre-conference on-line portion and an on-site portion during the ISA-16 workshop.

The series of International Conferences on Logic for Programming, Artificial Intelligence and Reasoning (LPAR) is a forum where, year after year, some of the most renowned researchers in the areas of logic, automated reasoning, computational logic, programming languages and their applications come to present cutting-edge results, to discuss advances in these fields, and to exchange ideas in a scientifically emerging part of the world.

The ACL2 Workshop series is the major technical forum for users of the ACL2 theorem proving system to present research related to the ACL2 theorem prover and its applications. ACL2 is an industrial-strength automated reasoning system, the latest in the Boyer-Moore family of theorem provers.

The Logical Perspectives summer school and workshop series aims at giving advanced introductions into various branches of logic, and providing researchers - including early career scientists - an opportunity to present their work. In particular, the Logical Perspectives 2020 Summer School and Workshop (LP 2020 SW) will be concerned with computational proof theory, broadly understood. It will take place in Moscow on June 15-19, 2020, following LP 2020. The programme of LP 2020 SW will comprise three mini-courses on different aspects of computational proof theory, and also a number of contributed talks.

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

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

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

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

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

The Institute of Philosophy of the The Czech Academy of Sciences announces 'LOGICA 2020', the 33nd in the series of annual international symposia devoted to logic. Rhe first session begins on the morning of Tuesday, 16 June. The symposium closes at noon on Friday, 19 June.

Invited speakers: Katalin Bimbo, Rosalie Iemhoff, Alena Vencovska and Diderik Batens.

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

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

There are several new and rapidly evolving research areas blossoming out from the interaction of logic and relativity theory. The aim of this conference series, which take place once every 2 or 3 years, is to attract and bring together mathematicians, physicists, philosophers of science, and logicians from all over the word interested in these and related areas to exchange new ideas, problems and results.

The spirit of this conference series goes back to the Vienna Circle and Tarski's initiative Logic, Methodology and Philosophy of Science. We aim to provide a friendly atmosphere that enables fruitful interdisciplinary cooperation leading to joint research and publications.

We are in the reality of natural and computational systems of argumentation provided by reasoning, with natural and artificial languages. Intelligent systems of argumentation target advanced methods for exchanging, saving, reasoning, accessing, and updating information in memory. There will be a Special Session on Natural Language and Argumentation 2020 (NLA'20) at DCAI'20, the 17th International Conference on Distributed Computing and Artificial Intelligence. This special session will cover both theories and applications.

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

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

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

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

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.

We would like to invite you to the next European Symposium of Medieval Logic and Semantics, which will take place at the University of Warsaw on 22-25 June 2020. The topic of the conference is 'Time, Tense, and Modality', and covers logical, semantical, and grammatical problems related to time. It is meant to include a wide range of issues occurring in medieval writings, not restricted to narrowly understood field of artes.

From the end of the 19th century, mathematical and philosophical literature has often portrayed a contrast between visual intuition and logical rigor. However, the terms "rigour" and "intuition" have rich associations and connotations in different historical contexts, and well before the turn of the 20th century. The goal of our workshop is to study the historical evolution of these notions within the mathematical practice, and the epistemological debates that they have raised.

Confirmed keynote speakers are: Helena Durnova (Masaryk University, Brno) Michael Friedman (Humboldt University, Berlin) Eduardo Giovannini (University of Wien) Marco Panza (CNRS, Universit́e Paris 1/Chapman University) Vincenzo de Risi (CNRS, Universit́e Paris 7).

Six courses will be offered. No parallel sessions are planned, so it will be possible to attend them all. Attendees who want to obtain ECTS points will be able to do so by giving a short presentation on June 26th. The courses are:

Fan Yang: Proof theoretic aspects of dependence logics
Peter Fritz: Necessitism vs contingentism
Nina Gierasimczuk: Learning and Modal Logic
Paulo Oliva: Proof interpretations and constructive mathematics
Thomas Powell: Proof Mining
Sonja Smets: Logics for Epistemic Social Networks

Computational Creativity (or CC) is a discipline with its roots in Artificial Intelligence, Cognitive Science, Engineering, Design, Psychology and Philosophy that explores the potential for computers to be autonomous creators in their own right. ICCC is an annual conference that welcomes papers on different aspects of CC, on systems that exhibit varying degrees of creative autonomy, on frameworks that offer greater clarity or computational felicity for thinking about machine (and human) creativity, on methodologies for building or evaluating CC systems, on approaches to teaching CC in schools and universities or to promoting societal uptake of CC as a field and as a technology, and so on.

The International Conference on Theory and Applications of Satisfiability Testing (SAT) is the premier annual meeting for researchers focusing on the theory and applications of the propositional satisfiability problem, broadly construed. In addition to plain propositional satisfiability, it also includes Boolean optimization (such as MaxSAT and Pseudo-Boolean (PB) constraints), Quantified Boolean Formulas (QBF), Satisfiability Modulo Theories (SMT), and Constraint Programming (CP) for problems with clear connections to Boolean-level reasoning.

Rewriting is a powerful model of computation that underlies much of declarative programming and is ubiquitous in mathematics, logic, theorem proving, verification, model-checking, compilation, biology, chemistry, physics, etc. The school is aimed at Master and PhD students, researchers and practitioners interested in the use or the study of rewriting and its applications.

We intend to offer on the one hand a basic track on rewriting and on lambda calculus, and on the other hand an advanced track on more specialized topics, related to state-of-the-art research and novel applications. The typical day will contain 4 slots of 90 minutes.

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

The Society for Philosophy of Science in Practice (SPSP) is an interdisciplinary community of scholars who approach the philosophy of science with a focus on scientific practice and the practical uses of scientific knowledge. The SPSP conferences provide a broad forum for scholars committed to making detailed and systematic studies of scientific practices - neither dismissing concerns about truth and rationality, nor ignoring contextual and pragmatic factors. The conferences aim at cutting through traditional disciplinary barriers and developing novel approaches.

Keynote speakers: Karen Barad, University of California at Santa Cruz; Till Grüne-Yanoff, Royal Institute of Technology (KTH) Stockholm.

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 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.

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.

This is a workshop on “Logics of Dependence and Independence” consisting of a 5-day programme of invited and contributed talks. Logics of dependence and independence are novel non-classical logics aiming at characterizing dependence and independence notions in sciences. This field of research has grown rapidly in recent years. The framework of the logics has found applications also in fields like database theory, linguistics, social choice, quantum physics and so on. This workshop will bring together researchers from all these relevant areas and provide a snapshot of the state of the art of logics of dependence and independence.

The workshop is organized as part of the 32nd European Summer School in Logic, Language and Information (ESSLLI 2020).

Advances in Modal Logic is an initiative aimed at presenting the state of the art in modal logic and its various applications. The initiative consists of a conference series together with volumes based on the conferences. AiML 2020 is the 13th conference in the series.

Invited Speakers:
Bahareh Afshari (University of Amsterdam and Gothenburg University)

Nick Behanishvilii (University of Amsterdam)
Melvin Fitting (City University of New York)
Nina Gierasimczuk (Danish Techical University, Copenhagen)

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.

Logical and semantic frameworks are formal languages used to represent logics, languages and systems. These frameworks provide foundations for the formal specification of systems and programming languages, supporting tool development and reasoning.

The biennial European Conference on Artificial Intelligence (ECAI) is Europe's premier venue for presenting scientific results in AI. Under the general theme 'Paving the way towards Human-Centric AI', the 24th edition of ECAI will be held in Santiago de Compostela, a UNESCO's World Heritage City which is the destination of unique Routes that cross all Europe since the Middle Ages.

Strategic reasoning is a key topic in multi-agent systems research. The extensive literature in the field includes a variety of logics used for modeling strategic ability. Results from the field are now being used in many exciting domains such as information system security, adaptive strategies for robot teams, and automatic players capable to outperform human experts. A common feature in all these application domains is the requirement for sound theoretical foundations and tools accounting for the strategies that artificial agents may adopt in the situation of conflict and cooperation.

The SR international workshop series aims at bringing together researchers working on different aspects of strategic reasoning in computer science, both from a theoretical and a practical point of view. SR 2020 will be held with ECAI 2020 in Santiago de Compostela, Spain.

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

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

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

This workshop focuses on the issues of information spread in a social network of natural and artificial agents as studied by the emerging interdisciplinary field of multi-agent systems, reasoning and social network analysis.

We would like to invite you to participate in a workshop 'Krajíček's Fest' on the Logical Foundations of Complexity Theory, to celebrate Prof. Jan Krajicek's 60th anniversary and his Contributions to Logic and Complexity

The event will be followed by a 3-day workshop on Complexity Theory which will include tutorials and contributed talks.

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).

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".

Christian Fermüller (TU Wien), Daniele Mundici (University of Florence), Norbert Preining (Accelia Inc.), James Raftery (University of Pretoria).

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.

Knowledge Representation and Reasoning (KRR) is an exciting, well-established field of research. In KRR a fundamental assumption is that an agent's knowledge is explicitly represented in a declarative form, suitable for processing by dedicated reasoning engines. This assumption, that much of what an agent deals with is knowledge-based, is common in many modern intelligent systems. In recent years KRR has contributed to new and emerging fields including the semantic web, computational biology, and the development of software agents. The biennial International Conference on the Principles of Knowledge Representation and Reasoning (KR) is a leading forum for timely, in-depth presentation of progress in the theory and principles underlying the representation and computational management of knowledge.

Large-scale semantic processing and strong computer assistance of mathematics and science is our inevitable future. New combinations of AI and reasoning methods and tools deployed over large mathematical and scientific corpora will be instrumental to this task. The AITP conference is the forum for discussing how to get there as soon as possible, and the force driving the progress towards that.

There will be several focused sessions on AI for ATP, ITP and mathematics, Formal Abstracts, linguistic processing of mathematics/science, modern AI and big-data methods, and several sessions with contributed talks. The focused sessions will be based on invited talks and discussion oriented.

The Joint Ontology WOrkshops (JOWO) is a venue of workshops that, together, address a wide spectrum of topics related to ontology research, ranging from Cognitive Science to Knowledge Representation, Natural Language Processing, Artificial Intelligence, Logic, Philosophy, and Linguistics.

Workshops and tutorials at JOWO 2020 are events whose scientific program is independently established by the workshop organizers.  Workshops can be events that provide a forum for the discussion of topics broadly related to ontologies, formal ontology, and knowledge management and their application in information science or other areas. JOWO is especially suitable for interdisciplinary and innovative formats.

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

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.

The Colloquium Logicum is organized every two years by the "Deutsche Vereinigung fuer Mathematische Logik und fuer Grundlagenforschung der Exakten Wissenschaften" (DVMLG).The conference will cover the whole range of mathematical logic and the foundations of the exact sciences. In addition to all fields of mathematical logic, this includes the philosophy of the exact sciences, logic in philosophy, and logic in computer science and artificial intelligence. In addition to the keynote talks, there will be a "PhD Colloquium" with invited presentations of excellent recent PhD graduates.

Keynote Speakers: Laurent Bienvenu (Bordeaux), Catrin Campbell-Moore (Bristol), Wesley Holliday (Berkeley), Christian Ikenmeyer (Liverpool), Angeliki Koutsoukou-Argyraki (Cambridge), Alison Pease (Dundee) and Margaret Thomas (West Lafayette).

 - Consolidate collaborations between these two communities and foster new ones.

Invited Speakers: Giuseppe de Giacomo (Sapienza Universita' di Roma, Italy) and  Jane Hillston (University of Edinburgh, UK).

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

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

Computer Science Logic (CSL) is the annual conference of the European Association for Computer Science Logic (EACSL). It is an interdisciplinary conference, spanning across both basic and application oriented research in mathematical logic and computer science.
