Abstract : Local cultural heritage document collections are characterized by contents strongly attached to a territory and its associated land history. Our contribution aims at enhancing such a content retrieval process efficiently each time a query includes geographic criteria. We propose a unified model for a formal representation of geographic information. This geographic model allows space features to be described independently of their representation mode text, graphics in the documents. We have developed a prototype implementing geographic Information Extraction IE and geographic Information Retrieval IR processes. We process geographic IE with semantic techniques combined to classic IE approaches. Then, we implement geographic IR with intersections researching algorithms: these algorithms search for all geocoded entities in the documents collections indexes which intersect any entity in the user-s query. This paper focuses on IR and Visualization proposals relying on the geospatial characteristics of cultural heritage corpora.
