| 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基于Web的信息系统检索模型的构造，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作了模糊化改进，初步实验结果表明，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。

| Abstract: | The VCM (Vector_Correlative Model) is one of the currently popular models for information searching under the Web environment. In this paper, the authors inducted fuzzy sets theory and approach to construct information searching model, and a new VCM is presented, that is called FVCM(Fuzzy Vector_Correlative Model). So, its theory structure and user's searching quizzing mode have been dimming improved. It has been shown with some fringe experimentation that the new model has overcome some intrinsic defects of the exciting ones, and has raised the precision rate and recall rate of information search system. |
