Title

Two-level document ranking using mutual information in natural language information retrieval

Source

Information processing and management. 33(1997) no.3, S.289-306

Year

1997

Abstract

Discusses a model of a natural language information retrieval system that is based on a 2-level document ranking method using mutual information. Retrieves documents based on automatically constructed index terms. Reorders the retrieved documents using mutual information. Shows that the method achieves retrieval effectiveness improvement over a traditional linear searching methods. Analyzes 7 newly developed formulas that reorder the retrieved documents. Among the 7 formulas, recommends 1 formula that dominates the others in terms of retrieval effectiveness
