Abstract
In this paper we describe the participation of the Universidad Politécnica of Valencia to the 2006 edition, which was focused on 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. JIRS is based on n-grams, Lucene on keywords. We participated in three monolingual tasks: Spanish, Italian and French. The obtained results show that JIRS is able to return high quality passages, especially in Spanish. © Springer-Verlag Berlin Heidelberg 2007.
