| 摘 要： | 虽然传统的向量空间模型被誉为检索模型中最富有想象力和创造力的模型，但是它同时也存在着一些考虑不足的地方，如未考虑文档结构、文档类型等问题。本文就这些问题给予分析并给出了相应的改进方法，最后构建了一个改进后的向量空间模型。

| Abstract: | Although the traditional vector space model is praised as the most imaginative and creative one among retrieval models, it also has some deficiencies, for example, the structure and the type of the file have not been taken into consideration. This paper gives an analysis of these problems and provides some corresponding method for improvement. Finally, an improved vector space model is presented. |
