文中详细比较了派生式CAPP与产品变型设计的工作过程，给出了基于相似性原理的产品分类编码方法，提供了一套相对独立的产品变型设计特性代码操作机制。

In addition, building a sentiment word dictionary, we have a sentiment classification about product feature based on the dictionary, and show the result in the way of graph. Finally, designing and implementing a product review mining system.
