Tratamiento lingüístico de las preguntas en español en los sistemas de búsqueda de respuestas / Linguistic treatment of questions in Spanish for question classification in question answering systems

We propose a procedure for the linguistic treatment of Spanish questions as a step prior to their classification in question answering systems. The main types of question answering systems and their basic architecture are described. We review the principal question classification taxonomies used to date and the different fields from which they have been derived. Finally, we present the stages of linguistic analysis that the text of questions in question answering systems should be subject to in order to facilitate the location of appropriate answers
