La composante temps dans l'information géographique textuelle. Extraction et recherche d'information dans des fonds documentaires patrimoniaux numérisés

These works take place in the geographical information retrieval context. Our purpose is to exploit local cultural heritage document repositories whose content is strongly attached to a territory (i.e. geographical information). Geographical information is composed of a spatial feature, a temporal feature and a theme feature. This paper focuses on temporal feature. We first propose a model for temporal expressions to annotate. Then, we present a semantic annotation methodology for automatically indexing these expressions. Finally, we start on geographical information retrieval according respectively to spatial, theme and temporal criterions, and then we combine them. MOTS-CLÉS : recherche d’information, information spatiale, information temporelle, information thématique, sémantique des contenus
