This paper describes the participation of the system AliQAn, a monolingual opendomain Question Answering (QA) System developed in the Department of Language Processing and Information System at the University of Alicante, in the CLEF-2008 Spanish monolingual QA evaluation task. Here, we focus on explaining a couple of strong points of the current version of AliQAn: (i) our algorithm for dealing with topic-related questions, and (ii) our approach for decreasing the number of inexact answers. We have also explored the use of the Wikipedia corpora, which have proposed some new challenges for the QA task. Besides, the achieved results (overall accuracy of 19.50%) are shown and discussed in this paper.
