It mainly finished the following several jobs. Pretreated the documents. Improved the Okapi term weighting formula. It also separated the term weighting and completed attributes reduction and rules extraction tasks. Firstly it reduced the feature vector dimensions by using discernible matrix. Then reduced it again by computing relative reductions.
主要完成了以下几个方面的任务：对文本进行了预处理；改进了Okapi权重计算公式，并对权值进行了离散化；实现了属性约简和规则抽取，首先利用区分矩阵对特征向量维数进行了初次压缩，然后通过相对约简计算再次压缩了特征向量维数，并生成了决策规则；采取了规则合成的策略，生成最终的决策规则；设计了一种文本与规则的匹配算法，使匹配过程尽可能简单有序。
