Plate-forme pour l'indexation spatiale multi-niveaux d'un corpus territorialisé

Abstract : The aim of our work is to provide a more easier way to access documents in territorial copora and, particularly, spatial information contents. We suggest to go further than classical based-statistic information retrieval systems that are not suitable in the case of spatial information extraction. A light linguistic process can rather be used in order to draw the information's main thing. They can be a good starting point to be used thereafter in a more precise interpretation process, using only the geographic properties extracted, in order to propose a multi-level indexing method, each level corresponding to an abstraction level of spatial information.
Thus, we propose a multi-levels spatial information retrieval system, indexing unstructured textual documents. This method, that interprets spatial information, allows to improve the efficiency of information retrieval systems each time a spatial query is performed. This interpretation can also retrieve the context in which the spatial information is used by the author. Particularly, text units can be classified in itinerary, local description or area comparison contexts.
