Analyse sémantique des adverbiaux de localisation temporelle : application à la recherche d'information

This work addresses the issue of accessing the content of digital texts, in so as it is anchored in time. The aim of this work is twofold: it consists in conciliating a linguistic approach and an applied approach, to participate in the development of new tools for text mining and information retrieval. It is thus both about implementing interaction systems and modeling the semantics of one the most salient textual units that contributes to anchor in time the situations described in texts: temporal locating adverbials. The linguistic analysis aims to show that language engineering can benefit from considering in a new way the “temporal expressions” in texts, by seeking to uncover the different semantic operations at work in temporal locating adverbials. Pinpointing the semantic values of these operations, we show that it becomes possible to develop new Information Retrieval systems, able of processing queries involving both a calendar criterion and a set of keywords, such as "universities in the early twelfth century", for instance. MOTS-CLÉS : analyse sémantique, adverbiaux de localisation temporelle, recherche d’information.
