This paper describes the fourth participation of the IR-n system (Alicante University) at the CLEF evaluation campaigns. For CLEF 2004, we modified our similarity measure and query expansion model. For the similarity measure, we now use normalization based on the number of words for each of the passages. We tested two different approaches for query expansion: the first one is based on documents and the second on passages.
