The Key to the First CLEF with Portuguese: Topics, Questions and Answers in CHAVE

In this paper we report the work done by Linguateca in order to add Portuguese to two tracks of CLEF, namely the ad hoc IR and the QA tracks. We start with a brief description of Linguateca’s aims and the way we see CLEF from the standpoint of Portuguese language processing. We then comment on several interesting problems that emerged during our work and offer some suggestions for improvement, and finally raise some possibly controversial points for discussion.
