Recherche d'Information et temps linguistique : une heuristique pour calculer la pertinence des expressions calendaires

Abstract : Unlike many nowadays applications providing Information Retrieval services able to handle temporal criteria - applications which usually filter results after testing their inclusion in a time span, this paper illustrates the interest of a service based on a calculation of similarity between calendar adverbial phrases. We describe a heuristic to measure the relevance of a fragment of text by taking into account the semantics of calendar expressions. Through the implementation of an Information Retrieval system, we show how it is possible to take advantage of the indexing of calendar expressions found in texts by setting scores of relevance with respect to a query. The objective is to ease Information Retrieval by offering the possibility of crossing thematic research criteria with temporal criteria.
