In information retrieval, vector space model is one of significant mathematics tools. Because of the speciality of natural language retrieval (NLR) and the affection of synonym and polysemy in tradition information retrieval model, the precision of retrieval is not high. In order to imporve the precision of NLR, the authors discuss information retrieval model based on concept--Latent Semantic Indexing (LSI), and analysis two examples of LSI.
