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

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

The initial conference was scheduled August 2020 to be held in Riga, Latvia; this is the postponed version of it.The participants will receive the details and updates about Zoom events by email when the registration closes on July 25, 2021.

Diagrams 2021 is the twelth conference in the series that started in 2000. The multidisciplinary nature of Diagrams means it encompasses: architecture, art, artificial intelligence, biology, cartography, cognitive science, computer science, education, graphic design, history of science, human-computer interaction, linguistics, logic, mathematics, philosophy, psychology, and software modelling. The conference attracts a large number of researchers from these interrelated fields, positioning Diagrams as the major international event in the area.

In addition to the Philosophy track, Diagrams 2021 will have two further tracks: Main, and Psychology and Education.

The thirteenth edition of the French Philosophy of Mathematics Workshop (FPMW) will be held from the 7th to the 9th of October 2021 at the Université Côte d'Azur in Nice.

This year, the invited speakers are: Hourya BENIS SINACEUR (CNRS, IHPST), Valeria GIARDINO (CNRS, Institut Jean-Nicod), Patrick POPESCU-PAMPU (Université de Lille, laboratoire Paul-Painlevé), Dominique PRADELLE (Sorbonne Université, Archives Husserl) and Dirk SCHLIMM (McGill University).

ETAPS is the primary European forum for academic and industrial researchers working on topics relating to software science. ETAPS, established in 1998, is a confederation of four annual conferences, accompanied by satellite workshops:

• ESOP: European Symposium on Programming
• FASE: Fundamental Approaches to Software Engineering
• FoSSaCS: Foundations of Software Science and Computation Structures
• TACAS: Tools and Algorithms for the Construction and Analysis of Systems

A number of satellite workshops will take place before the main conferences. TACAS '21 will also host the 10th Competition on Software Verification (SV-COMP).

Due to the ongoing COVID-19 pandemic, ETAPS 2021 will take place virtually only.

Semantic Spaces at the Intersection of NLP, Physics, and Cognitive Science (SemSpace2021) is the latest edition of a series of workshops that brings together research at the intersection of NLP, Physics, and Cognitive Science. Using the common ground of vector spaces, the workshop offers researchers in these areas an appropriate forum for presenting their uniquely motivated work and ideas. The interplay between the three disciplines will foster theoretically motivated approaches to understanding how meanings of words interact with each other in sentences and discourse via grammatical types, how they are determined by input from the world, and how word and sentence meanings interact logically.

This year we are excited to be (virtually) co-located with IWCS.

The academic activity of the Carl Friedrich von Weizsäcker Center (University of Tübingen) will be opened with the online event "Making Responsible Decisions in and about Science".

The aims of FMAI 2021 are to:
 - Present success stories about the application of formal methods in AI.
 - Discuss strategies for bringing the Formal Methods and the AI communities closer together.
 - Consolidate collaborations between these two communities and foster new ones.

The programme features 3 invited talks (by Giuseppe de Giacomo, Jane Hillston and Dvijotham Krishnamurthy) and 6 thematic sessions (on Learning, LTL, Logic, Verification, Data, and Games and MAS).

Formerly FMAI 2020, due to the current COVID-19 pandemic the workshop has been postponed to Spring 2021.

Unification is concerned with the problem of identifying given (first- or higher-order) terms, either syntactically or modulo a theory. It is a fundamental technique that is employed in various areas of Computer Science and Mathematics. In particular, unification algorithms are key components in completion of term rewriting systems, resolution-based theorem proving, and logic programming. But unification is, for example, also investigated in the context of natural language processing, program analysis, types, modal logics, and in knowledge representation.

UNIF 2021 is the 35th in a series of annual workshops on unification and related topics. Just as it predecessors', the purpose of UNIF 2021 is to bring together researchers interested in unification theory and its applications, as well as closely related topics, such as matching (i.e., one-sided unification), anti-unification (i.e., the dual problem to unification), disunification (i.e., solving equations and inequations) and the admissibility problem (which generalizes unification in modal logics). It will provide a forum for presenting recent (even unfinished) work, and discuss new ideas and trends in this and related fields. UNIF 2021 is associated with FSCD 2021 and will be a purely virtual event.

The TYPES meetings are a forum to present new and on-going work in all aspects of type theory and its applications, especially in formalised and computer assisted reasoning and computer programming.

This year's TYPES will be held virtually (online), possibly in combination with a physical meeting in Leiden in the Netherlands if the political situation permits that. TYPES 2021 will not only consist of presentations, but also a setup of working groups that get together throughout the week. The hope is that we can retain at least some of the exchange and chatter that is the heart of the TYPES conference series.

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 progress in computer-aided reasoning, both automatic and interactive, during the past decades, has made it possible to build deduction tools that are increasingly more applicable to a wider range of problems and are able to tackle larger problems progressively faster. In recent years, cooperation of such tools in larger verification environments has demonstrated the potential to reduce the amount of manual intervention. Examples include the Sledgehammer tool providing an interface between Isabelle and (untrusted) automated provers, and collaboration of the HOL Light and Isabelle systems in the formal proof of the Kepler conjecture.

Cooperation between reasoning systems relies on availability of theoretical formalisms and practical tools for exchanging problems, proofs, and models. The PxTP workshop strives to encourage such cooperation by inviting contributions on suitable integration, translation, and communication methods, standards, protocols, and programming interfaces. The workshop welcomes developers of automated and interactive theorem proving tools, developers of combined systems, developers and users of translation tools and interfaces, and producers of standards and protocols. We are interested both in success stories and descriptions of current bottlenecks and proposals for improvement.

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

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

Artificiële intelligentie moet ons leven verrijken, maar er niet mee aan de haal gaan. Het moet zich houden aan door mensen gehanteerde logica en principes voor rationaliteit, moraliteit en consistentie. Kortom, wij willen machinaal handelen kunnen begrijpen en sturen. Mens en machine moeten elkaar in voldoende mate verstaan om op de gewenste manier met elkaar om te gaan.

Vier sprekers (Catholijn Jonker, Jan Broersen, Rineke Verbrugge en Bart Jacobs) leggen uit welke rol logica, in combinatie met probabilistisch denken, speelt in het onderzoek naar de vervulling van deze wensen.

The journal Linguistics and Philosophy (L&P) have agreed to publish a special issue of Super Linguistics.

High quality research papers concerning theory and applications of relating logics and relating semantics, including, but not limited to, the following topics, are welcome:
- applications of relating semantics,
- algebraic interpretation of relating logics,
- comparison of relating semantics with other formal semantics, - history of relating logics,
- modal extensions of relating logics,
- model theory of relating logics,
- philosophical logics defined by relating semantics,
- proof theory for relating logics,
- philosophical foundations of relating logics,
- other related topics (like dependence logic, set-assignment semantics etc.).
Contributions are welcome from philosophers, logicians, mathematicians, linguists, and computer scientists.

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 2021 is a satellite event of the 36th Annual ACM/IEEE Symposium on Logic in Computer Science (LICS'21) to be held virtually on June 29-July 2, 2021.

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.
