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.

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).

CoNLL is a yearly conference organized by SIGNLL (ACL's Special Interest Group on Natural Language Learning). This year, CoNLL will be colocated with ACL 2025. The focus of CoNLL is on theoretically, cognitively and scientifically motivated approaches to computational linguistics, rather than on work driven by particular engineering applications.
