We examine the impact of using these two common resources in answering definition questions by varying the use of WordNet and two types of Web resources in statistical ranking, and definition patte...

This paper presents a Multiple Combined Ranker (MCR) approach for answering definitional questions. Generally, our MCR approach first extracts question target-related knowledge as much as possible, then using this knowledge to pick up appropriate question answers. The knowledge includes both online definitions and related terms (RT). In our system, extraction of related terms is different from ...
