Typage de noms toponymiques à des fins d'indexation géographique
Résumé
This paper presents an automatic annotation of spatial expressions enabling the improvement of the indexing process of non-structured geographic information. The proposed method combines the use of specific intra-sentential relationships and external resources. It relies on expanded spatial named entities recognition to deduce a symbolic representation expressed in terms of semantic features, on the one hand, and, to give them a numerical representation, on the other hand. Our method completely implemented and was tested on a corpus of travelogues.
