The UPV at QA@CLEF 2006

This report describes the work done by the RFIA group at the Departamento de Sistemas Informáticos y Computación of the Universidad Politécnica of Valencia for the 2006 edition of the CLEF Question Answering task. We participated in three monolingual tasks: Spanish, Italian and French. The system used is a slightly revised version of the one we developed for the past year. The most interesting aspect of the work is the comparison between a Passage Retrieval engine (JIRS) specifically aimed to the Question Answering task and a standard, general use search engine such as Lucene. Results show that JIRS is able to return high quality passages.
