Multi-party Dialogue Games for Distributed Argumentation System

This paper concerns a distributed argumentation system where different agents are equipped with argumentative knowledge base (henceforth referred as KB) within which conflict arguments are represented using attacking relations. This paper proposes the notion of "defensibility" of an argument in a distributed argumentation system and a multi-party dialogue game to compute the defensibility of an argument. In our approach, we have proposed the notion of critical factor, legal move function and critical countermeasure, for avoiding idle attack and invalid attack in the course of dialogues. It is anticipated that this research will contribute to argumentation research in MAS.
