Etude en corpus des réalisations linguistiques de la relation d'Elaboration

Abstract : The purpose of our thesis is to study linguistic realizations of discourse relations, considering especially the relation of Elaboration. We get onto this study by taking into account models of discourse structure with an aim of linguistic description, linguistic formalization, corpus exploration and computational processing of this structure. Until now, there have been few studies based on Elaboration. This lack of interest as regards this relation can be explained by the fact that it does not have any prototypical marker. Nevertheless, this relation can often be found in texts and has a central role in discourse structure. To get through this study, we adopt a pragmatic-semantic approach of discourse structure, using the SDRT (Segmented Discourse Representation Theory) model. Confronting the onomasiologic approach (starting from the relation) and the semasiologic approach (starting from a marker or a cue) is totally relevant for the study of this relation, due to the absence of prototypical markers. Our objective is of two kinds. We propose linguistic descriptions of markers, cues, and combinations of cues in order to enrich a discourse model and to allow an automatic or semi-automatic identification of the relation. The first stakes are essentially empirical. We aim at improving the descriptive analysis for this relation. The second stakes are more applicative. Indeed, an automatic detection of discourse relations is a very challenging task for computational linguistics.
