L'intentionnalité communicative dans le dialogue homme-machine en langue naturelle

Abstract : My thesis is about the modelization of the communicative intentions of human-computer dialog systems in natural language and more generally, about any artificial agent. The goal is to propose a model of processing that gives its own communicative intentions to the computer to interact with human users, so that optimal relevance of the computer utterances is certified.

My model is based upon the idea that the sense exchanged between dialog participants is not a pre-existing sense but, by opposition, a sense negotiated and co-constructed by participants during the dialog. This co-construction depends on the hypothesis of the existence of a common ground, that is a knowledge set assumptions and believes that the speaker thinks to be shared.

My work has consisted in defining a computer interactional memory allowing the sense negotiation task. This memory contains elements of three different states organized in tree diagrams. These elements become from interpretations of user's illocutionary acts and from inferences of the activities of the dialog system. We distinguish three activities: the applicative activity performs any service to the human user, the linguistic activity analyzes user utterances and generates system utterances, and the dialogical activity converses with the human user in the sense previously defined. Computer communicative intentions are generated from the recognition of a set of configurations that I have defined by analyzing empirically the possible tree structures. This principle that gives computer speech acts, is general and independent of the field application. It is just based on the structural shape of the memory elements (called MMU for Minimal Memory Unit) and the state of these elements.
