使用朴素贝叶斯文本分类的Python代码
应用背景朴素贝叶斯分类器是最成功的已知的学习分类文本文件的算法。我们将提供adatasetcontaining 20000新闻组消息从20个新闻组绘制。数据集包含20个新闻组的1000个文件。关键技术1.请请从 http://www.cs.cmu.edu/afs/cs/project/theo-11/www/naive-bayes.html 下载数据
2.分类是做 usingNaive 贝叶斯分类技术。
3.程序语言编写的 python。
4.Theaccuracyresult 是 98.7%是很好。
5.数据集很大,所以训练分类器的数据作为训练数据半休息一半作为测试数据
