Traditional fuzzy set model is based on term-term correlation matrix for fuzzy retrieval,which only considers term co-occurrence within documents.The paper presents a fuzzy set model based on similarity thesaurus which considers the similarity between term and query.And we add the query expansion into the model.To some extent,the retrieval performance is improved.
