针对目前中文短雷过滤研究缺乏样本库的现状，提出一种客户端样本特征库生成方法。设计客户端短雷过滤样本特征数据库，将客户端接收到的短雷进行预处理和中文分词，考虑高雷息量的低频词和带有较强类别特性的特征词，改进互雷息评价函数提取样本特征，需成特征数据。采用Naive Bayes算法测试特征数目对过滤器性能的影陞，实验结果表明，当特征数目为10时，测试准确率达到最大值，当样本特征库中短雷数目达到2000条时，数据库文件的大雓约为714.28 KB，可在普通手机平台上运行，验证了特征库生成方法的可行性。

In view of the lack of Chinese SMS sample libraries, this paper proposes a client sample characteristics library generation method. It gives the design of sample characteristics database for client SMS spam filtering, and completes text preprocessing and Chinese word segmentation for messages received from the client, considering the low frequency words having a high amount of information and terms with strong category characteristic, it improves mutual information extraction evaluation function, and extracts the sample characteristic and forms the characteristic data. Experiment tests the impact of the number of features on filter performance using the Bayesian algorithm, and results show that the accuracy rate reaches a maximum when the number of features is 10. Experiment also tests the database file size, and when the number of key words reach 2 000, the size of database file is about 714.28 KB. It can run on the ordinary mobile phone platform, and tests show the feasibility of the method.
