Les réseaux d'engagements comme méthode pour modéliser le comportement dialogique des agents

In this article, we present the web of commitment methodology that allows us to specify the dialogical behavior of agents from the commitments that can be contracted between them and from the links that can exist between those commitments. At first, we present the DIAGAL agent communication language which is based on social commitments and dialogue games that are defined as structures regulating the mechanism under which some commitments are discussed through the dialogue. Then, we present our social commitments model to explain how the agent who uses DIAGAL can use the dialogue games to manipulate the commitments. For that, we introduce the web of commitments concept which makes it possible to specify the causality links that exist between various commitments of a multi-agent system. Finally, we explain using an illustrative example how we could implement, through our simulator, our concepts and ideas.
