Extraction de dates saillantes pour la construction de chronologies thématiques (original) (raw)

Abstract

ABSTRACT We present an approach for detecting salient (important) dates in texts in order to automatically build event timelines from a search query (e.g. the name of an event or person, etc.). This work was carried out on a corpus of newswire texts in English provided by the Agence France Presse (AFP). In order to extract salient dates that warrant inclusion in an event timeline, we first recognize and normalize temporal expressions in texts and then use a machine-learning approach to extract salient dates that relate to a particular topic. For the time being, we have focused only on extracting the d ates and not the events to which they are related.
