Abstract. This paper describes the prototype developed by the Language Technologies Laboratory at INAOE for Spanish monolingual QA evaluation task at CLEF 2005. Our approach is centered in the use of lexical features in order to identify possible answers to factual questions. Such method is supported by an alternative one based on pattern recognition in order to identify candidate answers to definition questions. The methods applied at different stages of the system and prototype architecture for question answering are described. The paper shows and discusses the results achieved with this approach.
