建立虚拟软件数据分类的数据仓库，提取数据后对数据进行预处理，对分列属性进行惩罚-分配图分类，在分裂过程中使用信息增益比作为属性的分裂准则来对次要属性进行惩罚，保证惩罚-分配图细化准确。实验证明，能够提高虚拟软件分类的准确率，为用户正确的选择提供保证，具有很强的实用性。

Virtual software data classification of data warehouse was established, using SQL technology to extract the data after data preprocessing, to punish-ranked attribute assignment graph classification, in the process of division using infor-mation gain ratio as attribute of the split criteria to punish for secondary characteristics, guarantee the accuracy of the clas-sification punishment-allotment refinement. Experiments show that this method can greatly improve the accuracy of classi-fication of virtual software, ensure the right choice for the user, has a strong practicability.
