Système dialectique au travers duquel les agents argumentatifs jouent et arbitrent : vers une prise de décision collective et débattue

We propose in this paper DIAL, a framework for inter-agents dialogue, which formalize a deliberative process. This framework bounds a dialectics system in which argumentative agents arbitrate and play to reach an agreement. For this purpose, we propose an argumentation-based reasoning to manage the conflicts between arguments having different strengths for different agents. Moreover, we propose a model of argumentative agents which justify the hypothesis to which they commit and take into account the commitments of their interlocutors. In the scope of our dialectics system, a third agent is responsible of the final decision outcome which is taken by resolving the conflict between two players according to their competence and the advanced arguments.
