Abstract
This paper describes the first participation of the SINAI group of the University of Jaén in GeoCLEF 2006. We have developed a system made up of three main modules: the Translation Subsystem, that works with queries into Spanish and German against English collection; the Query Expansion subsystem, that integrates a Named Entity Recognizer, a thesaurus expansion module and a geographical information-gazetteer module; and the Information Retrieval subsystem. We have participated in the monolingual and the bilingual tasks. The results obtained shown that the use of geographical and thesaurus information for query expansion does not improve the retrieval in our experiments.
