Validation d'une méthodologie pour l'étude des marqueurs de la segmentation dans un grand corpus de textes

This research aims at validating a methodology for the study of segmentation markers in large corpora. Two indices signalling a thematic break in a text are proposed. The first is based on the presence of a paragraph mark and employs the odds ratio to identify the best markers. The second takes into account lexical cohesion between sentences via an index resulting from latent semantic analysis. These two indices were applied mainly to the study of temporal adverbial expressions in literary texts. The analyses carried out confirm a series of linguistic hypotheses about the segmentation function of temporal adverbials. MOTS-CLÉS : marqueurs de segmentation, adverbiaux temporels, paragraphe, analyse sémantique latente, expressions référentielles.
