This paper describes the third participation of the IR-n system (U. Alicante) in CLEF 2003. Two previous participations were focused on the Spanish monolingual task. This year, we participated in three different tracks: the multilingual track (four languages), the bilingual track (Italian-Spanish) and the monolingual track (Spanish, German, French, Italian). This paper describes the experiments carried out as training procedures in order to set up the main system features. The paper also shows the scores obtained using the test data. These results show that the IR-n system obtains good scores in the three tracks, above the average of the CLEF 2003 systems.
