支持向量机(Support Vector Machine)是Cortes和Vapnik于1995年首先提出的，它在解决小样本 、非线性及高维模式识别 中表现出许多特有的优势，并能够推广应用到函数拟合等其他机器学习问题中。支持向量机方法是建立在统计学习理论的VC 维理论和结构风险最小 原理基础上的，根据有限的样本信息在模型的复杂性（即对特定训练样本的学习精度，Accuracy）和学习能力（即无错误地识别任意样本的能力）之间寻求最佳折衷，以期获得最好的推广能力（或称泛化能力）。SVM理论的学习，请参考<a style="color: #336699; text-decoration: none;" href="http://www.blogjava.net/zhenandaci/category/31868.html">jasper的博客</a> 。
 LIBSVM 是*大学林智仁(Chih-Jen Lin)博士等开发设计的一个操作简单、易于使用、快速有效的通用 SVM 软件包,可以解决分类问题(包括 C−SVC 、ν−SVC )，回归问题(包括 ε − SVR 、v− SVR ) 以及分布估计(one − class − SVM ) 等问题,提供了线性、多项式、径向基和 S 形函数四种常用的核函数供选择，可以有效地解决多类问题、交叉验证选择参数、对不平衡样本加权、多类问题的概率估计等。<a style="color: #336699; text-decoration: none;" href="http://www.csie.ntu.edu.tw/~cjlin/libsvm/">LIBSVM</a> 是一个开源的软件包,。他不仅提供了 LIBSVM 的 C++语言的算法源代码,还提供了 Python、Java、R、MATLAB、Perl、Ruby、LabVIEW以及 C#.net 等各种语言的接口,可以方便的在 Windows 或 UNIX 平台下使用,也便于科研工作者根据自己的需要进行改进(譬如设计使用符合自己特定问题需要的核函数等)。
 文本分类，大致分为如下几件事情：样本 ，分词 ，特征提取 ，向量计算 ，分类训练 ，测试和调试 。
 
1.样本选择
搜狗语料 <a style="color: #336699; text-decoration: none;" href="http://www.sogou.com/labs/dl/c.html">http://www.sogou.com/labs/dl/c.html</a> ，下精简版吧，如果实验用用，这足够了，你要下107M的也可以。当然，你也可以自己找语料，不过麻烦点而已，把各大门户网站的对应频道下的文章都爬下来。
 
2.分词
Bamboo分词，这是基于CRF++的分词模块，既然是研究统计学习，分词也得用基于统计的不是，如果还是用一字典来分词，那就太out啦。
<a style="color: #336699; text-decoration: none;" href="http://code.google.com/p/nlpbamboo/wiki/GettingStarted">http://code.google.com/p/nlpbamboo/wiki/GettingStarted</a> 。安装完毕bamboo，还要下载训练好的模型（这个模型是基于人民日报1月语料）
<a style="color: #336699; text-decoration: none;" href="http://code.google.com/p/nlpbamboo/downloads/list">http://code.google.com/p/nlpbamboo/downloads/list</a> ，下载index.tar.bz2，解压到/opt/bamboo/index下。
因为咱主要目的是研究分类，不是分词，就不要去搞分词的训练了，如果想训练可以看我的另外一篇博客：<a style="color: #336699; text-decoration: none;" href="http://blog.csdn.net/marising/archive/2010/07/27/5769653.aspx">CRF++中文分词指南</a> 。
可以试试：/opt/bamboo/bin/bamboo -p crf_seg filename，如果成功证明装好了。
 稍微注意以下，搜狗的词库是gb2312的，所以，请转为utf8，再分词，这是python写的函数：输入一个文件名，转为utf8，再分词，分词文件以.seg为后缀。

分词结果如下：
一家刚刚成立两年的网络支付公司，它的目标是成为市值 100亿美元的上市公司。 这家公司叫做快钱，说这句话的是快钱的 CEO 关国光。他之前曾任网易的高级副总裁，负责过网易的上市工作。对于为什么选择第三方支付作为创业方向，他曾经对媒体这样说： “ 我能看到这个胡同对面是什么，别人只能看到这个胡同。 ” 自信与狂妄只有一步之遥 ―― 这几乎是所有创业者的共同特征，是自信还是狂妄也许需要留待时间来考证。
 
3.特征提取
 svm不是在高维模式识别具有优势吗，咋还要特征提取呢，把所有词都当成特征不就行了吗？对于词库来说，十几万的词是很常见的，把对类别区分度（GDP，CPI，股票对经济类的区分度就高，其他一些高频词，如我们，大家，一起等就没有区分度）高的词挑选出来，一来可以减少计算量，二来应该是可以提高分类效果。
 据说，开方检验（CHI）信息增益（IG）对于挑选特征好，我选择的是CHI。两者的概念，请google。
 首先统计词在文档中的次数
