Query expansion based on relevance feedback and latent semantic analysis
Web search engines are one of the most popular tools on the Internet which are widely-used by expert and novice users. Constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. Query expansion is a way to reduce this concern and increase user satisfaction. In this paper, a new method of query expa...

متن کاملDocument Refinement Based On Semantic Query Expansion
The word mismatch problem of various expressions of the same concept between known document resources and user query is one of the main factors that hurt the retrieval performance. This paper proposes a document refinement (DR) approach by expansion and replacement based on semantic relations between words. Different from traditional query expansion technology, this DR approach clusters the inf...
متن کاملQuery Expansion based on Associated Semantic Space
Expansion of query keywords based on semantic relations is an effective approach to improve the performance of information retrieval. Traditional methods of query expansion did not adequately make use of semantic relations between query keywords. In this paper, a novel approach for query expansion is presented. The main idea of the approach is to construct a ‘Tree of Associational Semantics Mod...
