Abstract

This paper is a report on our third participation in CLEF. More precisely, this year we have participated in the Spanish Monolingual Question Answering Track for the first time. As a result we have developed a prototype of a QA system. Our prototype continues to apply the Natural Language Processing techniques we had already developed for single word conflation. In addition, the question analysis is based on complex pattern matching either over forms, part-of-speech tags or lemmas of the words involved. Regarding the search for relevant parts of documents containing the required answer, we use conventional IR techniques, whilst the extraction of the answer from the relevant parts of documents is again based on pattern matching.
