GIR Experimentation

Geographic Information Retrieval (GIR) community has generally accepted the thesis that both thematic and geographic aspect of documents may be useful for GIR. This paper describes a preliminary experiment exploring this thesis by seperately indexing/searching geographical relevant-terms (place names, geo-spatial relations, geographic concepts and geographic adjacetives) extracted from reference document collection. Two indexes were created one for extracted geographic relevant-terms (i.e. document footprint) and one for reference document collections. Geo-Score and ThematicScore against document collection footprint and reference document collection respectively were combined through a linear interpolation to obtained the final score for document relevance ranking. We used several freely available geographic resources
