| 摘 要： | 传统的模糊集合模型基于词词关联矩阵来实现模糊检索,词词关联矩阵只考虑语词在文献内部的同时出现.本文提出了一个基于相似性叙词表的模糊集合模型,考虑语词与查询之间的相似性,并将查询扩展包含在此模型中,从而在一定程度上提高了检索性能.

| Abstract: | 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. |

| Keywords: | Fuzzy set model Similarity thesaurus Query expansion |
