This paper describes the prototype developed by the Language Technologies Laboratory at INAOE for Spanish monolingual QA evaluation task at CLEF 2004. Our approach is centered on the use of context at a lexical level in order to identify possible answers to factoid questions. This method is supported by an alternative one based on pattern recognition in order to identify candidate answers to definition questions. We describe the methods applied at different stages of the system and our prototype architecture for question answering. The paper shows and discusses the results we achieved with this approach.
