Title: Answerfinder: TREC 2003 and 2004 

Abstract: 

Diego Molla's Answerfinder system, a question answering system that uses minimal semantic representations for ranking potential answers to questions, was entered in the TREC Question Answering track in 2003. I will review the strategies used by Answerfinder; discuss its performance in TREC 2003; discuss recent improvements to its performance; and describe some of the changes that will need to be made for the TREC 2004 competition.
