IR-n, a passage retrieval system from University of Alicante, at Clef 2001.

Previous works showed that the use of document passages like basic unit of information, to calculate the relevance of a document to a question, improve the results of the information retrieval systems sensibly. However, IR community has not arrived to a consent about how to define those text passages so that the system can improve the efficiently. This paper reports on experiments with IR-n system, a information retrieval system based on the selection of passages of variable size as basic unit of information, in the monolingual (Spanish) and bilingual (Spanish-English) tasks at CLEF-2001. The IR-n system has been developed this year in the Language Processing and Information Systems research group at the University of Alicante.
