Cfp: ArgMAS 2009: Sixth International Workshop on Argumentation in Multi-Agent Systems, Budapest, May 11 or 12, 2009.

Argumentation can be abstractly defined as the interaction of different arguments for and against some conclusion. Over the last few years, argumentation has been gaining increasing importance in multi-agent systems, mainly as a vehicle for facilitating "rational interaction" (i.e., interaction which involves the giving and receiving of reasons). This is because argumentation provides tools for designing, implementing and analysing sophisticated forms of interaction among rational agents. Argumentation has made solid contributions to the practice of multi-agent dialogues. Application domains include: legal disputes, business negotiation, labor disputes, team formation, scientific inquiry, deliberative democracy, ontology reconciliation, risk analysis, scheduling, and logistics. A single agent may also use argumentation techniques to perform its individual reasoning because it needs to make decisions under complex preferences policies, in a highly dynamic environment. The workshop will be concerned with the use of the concepts, theories, methodologies, and computational models of argumentation in building autonomous agents and multi-agent systems. The workshop will solicit papers looking at both theory and practice. In particular, the workshop aims at bridging the gap between the vast amount of work on argumentation theory and the practical needs of multi-agent systems research. Topics: We solicit papers dealing with, but not limited to, the following areas: Computational models for argumentation Argumentation-based decision making Argumentation-based joint deliberation Argumentation-based persuasion Argumentation-based inquiry Argumentation-based negotiation and conflict resolution Argumentation and risk assessment Argumentation for legal reasoning Argumentation for electronic democracy Argumentation for coordination, cooperation and team formation Argumentation and game theory in multi-agent systems Human-agent argumentation Argumentation and preferences modelling Strategic behaviour in argument-based dialogues Deception, trust, reputation in argument-based interaction Computational complexity of argumentation dialogues Properties of argumentation dialogues (termination, success, etc.) Hybrid argumentation-based models Implemented argumentation-based multi-agent systems New application areas For more information, visit: http://homepages.inf.ed.ac.uk/irahwan/argmas/argmas09/.
