Abstract—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 multiparty dialogue game framework, we have proposed the notion of critical factor, legal move function and critical countermeasure, which act as the mechanism for avoiding idle attack and invalid attack in the course of dialogue games. Theoretically, the paper has also proved the soundness and completeness of multi-party dialogue games conducted by legal move and countermeasure function. It is anticipated that this research will contribute to argumentation research in MAS.

Index Terms—Argumentation; distributed argumentation system; multi-party dialogue games; multi-agent system.
