In order tofindthe solutionto derive key words/entries fromdocuments,this paper puts forward anew matrix-weighted mining association rule algorithm based on the weighted mining algorithm and theweighted value of vector space model.

• 针对自动从文档中导出关键词/词条之间的关联性问题,在研究加权挖掘算法和向量空间模型中权值特点的基础上,提出了一种新的矩阵加权关联规则挖掘算法。
