In view of the problem that the traditional information retrieval model can’t process uncertainty knowledge perfectly, the author combines rough set and fuzzy set theory, and puts forward an improved model of Web information retrieval based on fuzzy rough set. At the same time, the author proposes a key algorithm and a performance evaluation method performonce based on the model.The model is helpful to raise efficiency of information retrieval, and is valuable both in theory and application.
