Improving the Retrieval Effectiveness of Very Short Queries.
Crouch, Carolyn J.; Crouch, Donald B.; Chen, Qingyan; Holtz, Steven J.
Information Processing & Management, v38 n1 p1-36 Jan 2002
Describes an automatic approach designed to improve the retrieval effectiveness of very short queries such as those used in Web searching based on the observation that stemming, which is designed to maximize recall, often results in depressed precision. Discusses pseudo-feedback and reranking documents based on unstemmed query terms in the document text. Includes 21 tables. (Author/LRW)
