Services Web pour l'annotation sémantique d'information spatiale à partir de corpus textuels

Abstract : The semantic annotation of spatial information aims to identify words or phrases describing geographical references (place names) as well as various associated spatial expressions. One of the major difficulties in designing an automatic annotation system for such information is due to ambiguities related to spatial entities. A modular approach based on Web services was chosen. The proposed methodology is based on the combination of a pre-processing step using external morphosyntactic analysers, a cascade of transducers, and a classification step using linked data. An advantage of this approach is the possibility to obtain partial processing or to evaluate competing methods doing the same task.
