Dialogue entre agents naturels et agents artificiels. Une application aux communautés virtuelles

Abstract : In order to set up mixed communities in which natural agents (humans) and artificial agents are brought together, it is necessary to ensure smooth interactions. This thesis presents models of interaction and agent, based on the hypothesis that a message carries a potential meaning -subject to discussion- which has to be interpreted, and not one meaning -set and precisely defined- which only needs to be decoded. This hypothesis implies the two cornerstones of this thesis: contextual enhancement and conversational focus. The first point, contextual enhancement, associates a message to its context in a process of interpretation, instead of a simple decoding process, as is usual in typical information systems. Symmetrically, an expression process replaces the encoding. The second point, conversational focus, is a representation of the topic of the interaction. It is collectively built by the people involved in the interaction and subject to discussion, which naturally leads to conversational follow-up. A conversational agent for movies recommendation in a 3D virtual shop has been designed following the presented models, and several interactions between this agent and a human customer are analysed.
