Extraction et interprétation d'information géographique dans des données non structurées

This paper outlines the “Pyrénées Itinéraires Virtuels” project. The aim of this project is to add value to a legacy localised corpus. Unified models are proposed to define spatial entities in a formal way. These models allow to build a specific information retrieval system based on the semantic contents of various kinds of documents. Moreover, a reflection on computable interpretation of these spatial entities is performed, in order to be used in an information retrieval process. A prototype implementing this kind of information extraction and information retrieval process has been developped to validate our assumptions.
