Incorporating Syntactic Information in Question Answering

Abstract

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