The biennial International Conference on Deontic Logic and Normative Systems (DEON) conference series aims at bringing together researchers interested in the formal study of normative concepts, normative reasoning, and normative systems using methods from computer science, artificial intelligence, philosophy, linguistics, mathematics, and law. The series particularly aims at fostering interdisciplinary collaboration that combines methods from these various fields.

In addition to the general themes of the DEON conference series, DEON 2025 encourages the submission of papers on the special theme of Normative AI. The central aim of Normative AI is to ensure that AI systems make morally, legally, and socially acceptable decisions. As AI becomes increasingly important to human society, it is crucial to ensure that these technologies have a positive and responsible impact. This highly interdisciplinary field involves the evaluation and development of theories, formal frameworks, and algorithms, integrating both symbolic and sub-symbolic AI methods.

ECOOP is Europe’s longest-standing annual Programming Languages conference, bringing together researchers, practitioners, and students to share their ideas and experiences in all topics related to programming languages, software development, systems and applications. ECOOP welcomes high quality research papers relating to these fields in a broad sense. ECOOP was originally focused on object orientation, but now includes all practical and theoretical investigations of programming languages, systems and environments. ECOOP solicits innovative solutions to real problems as well as evaluations of existing solutions.

We are excited to kick off this series of Humane Conversations with a discussion on the interplay of AI and art. Join us as we bring together a panel of researchers and artists to explore how through artistic works we can communicate, reimagine, and reflect on AI technologies, and how art can be created through the advancements in AI tools.

This will be a hybrid event on Tuesday, 1 July, from 15:00 to 16:30, followed by drinks till 18:00. You are most welcome to join us in person at the Sweelinck room of the Institute of Advanced Study (IAS), Oude Turfmarkt 145-147, or online (link to be provided shortly). Please click on the link for registration and stay tuned for more details in the upcoming weeks!

In real-life AI applications, information is usually pervaded by uncertainty and subject to change, and thus requires non-classical systems. At the same time, psychological findings indicate that human reasoning cannot be completely described by classical logical systems. Sources of explanations are incomplete knowledge, incorrect beliefs, or inconsistencies. A wide range of reasoning mechanisms, such as analogical or defeasible reasoning, have to be considered, possibly in combination with machine learning methods. The field of knowledge representation and reasoning offers a rich palette of methods for uncertain reasoning, both to describe human reasoning and to model AI approaches.

This series of workshops aims to address recent challenges and to present novel approaches to uncertain reasoning and belief change in their broad senses, and in particular, provide a forum for research work linking different paradigms of reasoning. A special focus is on papers that provide a base for connecting formal-logical models of knowledge representation and cognitive models of reasoning and learning, addressing formal and experimental or heuristic issues. FCR'25 will be co-located with the 48th German Conference on Artificial Intelligence (KI 2025).

It is an interdisciplinary conference, spanning across both basic and application oriented research in mathematical logic and computer science.  CSL 2026 is the 34th edition of the conference and will be held in Paris on the 23-28 February 2026 and is organised by the Logic and Computation team of the LIPN of Sorbonne Paris Nord University.

Software systems are rapidly becoming more intelligent in the functionality they offer to users. They are also becoming more decentralized, with components that act autonomously and must communicate among themselves or with human users to achieve their goals. Examples of such systems include those in healthcare, disaster management, e-business, and smart grids. A multi-agent perspective is crucial to the proper conceptualization, deployment, and governance of these systems. Rooted in solid computational and software engineering foundations, this perspective offers abstractions such as intelligent agents, protocols, norms, organizations, trust and incentives, among others. As a large, but still growing research field of artificial intelligence, multi-agent systems today remain a unique enabler of interdisciplinary research.

CADE is the major international forum for presenting research on all aspects of automated deduction. CADE-30 aims to present research that reflects the broad range of interesting and relevant topics in automated deduction. The conference program includes invited talks, paper presentations, workshops, tutorials, and system competitions. 

Under the auspices of the Association for Logic, Language, and Information (FoLLI), the European Summer School in Logic, Language, and Information (ESSLLI) runs every year. Except for 2021, when the school was virtual, it runs in a different European country each year. It takes place over two weeks in the summer, hosts approximately 50 different courses at levels that run from foundational to introductory to advanced, and attracts around 400 participants from all over the world.

The main focus of ESSLLI is the interface between linguistics, logic and computation, with special emphasis on 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 evening lectures.

Registration for attendees is now open. The early-registration deadline is Saturday, 31st May.
