This paper describes our participation at the GeoCLEF 2005 task. We detail the main software components of our Geo-IR system, its adaptation for the participation at GeoCLEF and discuss the obtained results. The software architecture includes a geographic knowledge base, a text mining tool for geo-referencing documents, and a geo-ranking component to re-rank the results of a standard IR index according to geo-scopes. Evaluation shows that ranking with geographic scopes is heavily dependent on
