摘 要: 矢量相关模型VCM是当前流行的信息检索模型之一.本文将模糊集理论和方法引入检索模型的构造,提出了一种模糊矢量相关模型FVCM,从而对其理论结构及用户检索模式的表达机制做了模糊化改进.初步实验表明,新模型克服了原模型的一些固有缺陷,有利于提高系统查准率和查全率. : The vector-correlative model VCM is one of the popular information search models. In this paper,author induces fuzzy sets theory and approach to construct search models,and presentes an new VCM,that is Fuzzy Vector-correlative Model FVCM. So,its theory structure and user's retrieral mode has been Fuzzily improved.some experiments show that the new model can overcome some intrinsic defects of the exciting ones,and can raised the precision and recall of information search system.
