Belief Change and Argumentation in Multi-Agent Scenarios (Dagstuhl Seminar 13231)

This report documents the programme and outcomes of Dagstuhl Seminar 13231 "Belief Change and Argumentation in Multi-Agent Scenarios". The seminar brought together researchers from the fields of argumentation theory and belief revision, both from philosophy and computer science, to present recent research results and exchange ideas for combining argumentation and belief revision. A key objective of the seminar, moreover, has been to shed light on the applicability of these two fields in the area of multi-agent systems: Can both argumentation and belief revision be combined and used in a rational agent? Before revising its beliefs, how should an agent decide what, or what part of the new information should be believed? Can this deliberation before the proper revision process be performed by argumentation? The unique atmosphere of Dagstuhl provided again a perfect environment for leading researchers from a wide variety of backgrounds to discuss future directions of argumentation, belief revision and their applications in multi-agent systems.
