Abstract

This paper describes the participation of the Research Institute for Artificial Intelligence of the Romanian Academy (RACAI) to the Multiple Language Question Answering Main Task at the CLEF 2008 competition. We present our Question Answering system answering Romanian questions from Romanian Wikipedia documents focusing on the implementation details. The presentation will also emphasize the fact that question analysis, snippet selection and ranking provide a useful basis of any answer extraction mechanism.
