Comparing and Combining the Effectiveness of Latent Semantic Indexing and the Ordinary Vector Space Model for Information Retrieval.
Lochbaum, Karen E.; Streeter, Lynn A.
Information Processing and Management, v25 n6 p665-76 1989
Describes experiments that compared a new method for automatically analyzing semantic structures in text by statistical means with the standard vector space model. Findings indicate that combining both methods improved performance over either alone. The effects of other experimental variables on retrieval performance (term weighting, suffix stripping, and lexical units) are discussed. (19 references) (CLB)
