Transitions thématiques : Annotation d'un corpus journalistique et premières analyses (Manual thematic annotation of a journalistic corpus : first observations and evaluation) [in French]

Manual thematic annotation of a journalistic corpus : first observations and evaluation. The work presented in this paper focuses on the creation of a corpus of journalistic texts annotated at dicourse level, more precisely on a topic level. The annotation model is a classic segmentation one, to which we add transition zones between topical units. We assume that in a well-structured text, the author provides information helping the reader to move from one topic to another, where an identification of these clues is likely to improve automatic segmentation. The produced annotations have been subject of several quantitative analyses showing a set of linguistic properties of topical transitions.
