摘要: Abstract : Syntactic information potentially plays a much more important role in question answering than it does retrieval. The aim of the experiment described this paper is to study impact particular approach for using syntactic on effectiveness. TREC-9 QA track data are used evaluation. Our results indicate that combination with heuristics ranking potential answers can perform about 10% better their own.
