Abstract
We participated at four Question Answering tasks at CLEF 2005: the Italian monolingual (I), Italian-English (I/E), Bulgarian monolingual (B), and Bulgarian-English (B/E) bilingual task. While we did not change the approach in the Italian task (I), we experimented with several new approaches based on linguistic structures and statistics in the B, I/E, and B/E tasks.
