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.

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.

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).

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.

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.

ATVA 2020 is the 18th in the ATVA series of symposia intended to promote research in theoretical and practical aspects of automated analysis, verification and synthesis in Asia by providing a forum for interaction between the regional and international research communities and industry in the field.

The 12th edition of “PhDs in Logic” will take place at the Freie Universität Berlin, Germany, from April 27 to 29, 2020.

We welcome students to participate in PhDs in Logic XII regardless of whether they want to submit a contribution. Students interested in participating, even without giving a talk, are kindly asked to register.

Due to efforts to restrain the spreading of the Corona Virus, all public events at all Berlin Universities have been cancelled until the 20th of July 2020. When the situation has sufficiently cleared an alternative date will be selected.

The meeting “Quantum and Beyond” on 28 and 29 April 2020, is devoted to recent logical and foundational investigations that have been inspired by quantum theory. After the pioneering approach of Birkhoff and von Neumann in the Thirties, the quantum theoretic formalism has suggested the development of new logical ideas that have been successfully applied to different fields: fuzzy and epistemic logics, quantum information and quantum computation theories, semantics of natural and artistic languages, pattern recognition and machine learning, cognitive sciences.

"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.
