Etude des marqueurs discursifs dans le dialogue finalisé

Abstract : This study should be seen in the context of discourse analysis. The aim is to provide a method of analysis in order to recognise the performed dialogue acts. For this purpose, a corpus of fifteen spoken dialogues has been analysed, in which users are involved in a work situation. This study aims at determining several linguistic and contextual markers which account for the performed dialogue acts. The basic idea consists in the belief that the speaker gives in his utterance enough markers to be understood ; those discourse cues allow the listener to understand what speaker means. Three kinds of linguistic markers have been kept: markers which occur in the determination of the dialogue acts, connective markers, whose function is to indicate the structure of the dialogue and markers of cohesion which account for topic sequences. Those markers can be any item or lexical expression ; they can also be morphological or syntactical markers. The contextual information taken into account in our analysis are: the situation, the sequences of utterances, the roles held by the speakers in their task, and finally the prosodic and gestural information. A prototype has been elaborated: from observed linguistic and contextual information, it identifies the dialogue acts matching the utterances. This system has a model of utterance sequences. It takes into account the kind of dialogue act which is performed in each speech-turn, together with the role held by the speaker. Indeed, according to their role, the speakers do not ] perform the same acts in the same context. At last, the system has a set of knowledge about linguistic markers which are necessary to identify the performed acts. The task of the system consists in the recognition of the performed dialogue acts, and especially indirect dialogue acts. The problem is to determine the relevant markers which allow to understand what is performed through the utterances.
