Indexing implicit locations for geographical information retrieval
Local search has become a hot topic recently in information retrieval research area. How to retrieve geographical information correctly and efficiently is a key challenge to location-based search services. In this paper, we present a GIR (geographical information retrieval) system which uses implicit locations to improve retrieval performance. Experimental results based on Geo-CLEF 2006 (a cross-language geographical retrieval track which is part of Cross Language Evaluation Forum) data sets show that the proposed method can retrieve geographical information better than previous approaches. Keywords Location extraction, implicit location, geographical information retrieval.
