摘要
介绍了向量空间检索模式的基本原理,并针对其不能区分每个术语(term)在文档中出现的次数的缺点,提出了一种基于加权的改进的向量空间检索模式,很好地改进了此不足。
This paper introduces the primary theory of vector space retrieval model. According to the disadvantage of the VSM which can't distinguish the time of the term appearing in the document, we suggest an advanced VSM based on weight.
