<p><span style="font-family: Arial; font-size: 14px; color: #333333; line-height: 26px;">
<p>支持向量机(Support Vector Machine)是Cortes和Vapnik于1995年首先提出的,它在解决<strong>小样本</strong> 、<strong>非线性</strong>及<strong>高维模式识别</strong> 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<strong>VC 维理论和结构风险最小</strong> 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> 。</p>
<p> LIBSVM 是台湾大学林智仁(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)。</p>
<p> 文本分类,大致分为如下几件事情:<strong>样本</strong> ,<strong>分词</strong> ,<strong>特征提取</strong> ,<strong>向量计算</strong> ,<strong>分类训练</strong> ,<strong>测试和调试</strong> 。</p>
<p> </p>
<p><span style="font-size: medium;"><strong>1.样本选择</strong></span></p>
<p>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。</p>
<p> </p>
<p><span style="font-size: medium;">2.<strong>分词</strong></span></p>
<p>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。</p>
<p><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)</p>
<p><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。</p>
<p>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> 。</p>
<p>可以试试:/opt/bamboo/bin/bamboo -p crf_seg filename,如果成功证明装好了。</p>
<p> 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。</p>

<p>分词结果如下:</p>
<p>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 。<br>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 。</p>

<p><span style="font-size: medium;"><strong>3.特征提取</strong></span></p>
<p> 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。</p>
<p> 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。</p>
<p> 首先统计词在文档中的次数</p>

<p>支持向量机(Support Vector Machine)是Cortes和Vapnik于1995年首先提出的,它在解决<strong>小样本</strong> 、<strong>非线性</strong>及<strong>高维模式识别</strong> 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<strong>VC 维理论和结构风险最小</strong> 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> 。</p>
<p> LIBSVM 是台湾大学林智仁(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)。</p>
<p> 文本分类,大致分为如下几件事情:<strong>样本</strong> ,<strong>分词</strong> ,<strong>特征提取</strong> ,<strong>向量计算</strong> ,<strong>分类训练</strong> ,<strong>测试和调试</strong> 。</p>

<p><span style="font-size: medium;"><strong>1.样本选择</strong></span></p>
<p>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。</p>
<p> </p>
<p><span style="font-size: medium;">2.<strong>分词</strong></span></p>
<p>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。</p>
<p><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)</p>
<p><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。</p>
<p>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> 。</p>
<p>可以试试:/opt/bamboo/bin/bamboo -p crf_seg filename,如果成功证明装好了。</p>
<p> 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。</p>

<p>分词结果如下:</p>
<p>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 。<br>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 。</p>

<p><span style="font-size: medium;"><strong>3.特征提取</strong></span></p>
<p> 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。</p>
<p> 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。</p>
<p> 首先统计词在文档中的次数</p>

HTTP 请求方法与返回状态码 HTTP 是一个基于请求-响应模式的协议,客户端向服务器发送请求,服务器响应客户端的请求。HTTP 请求方法和返回状态码是 HTTP 协议的核心组成部分。 一、HTTP 请求方法 HTTP 请求方法是...
HTTP状态码是网络通信中用来标识客户端与服务器之间交互情况的重要信息。这些状态码由三位数字组成,分为五类,分别表示不同的响应状态。以下是各分类的详细解释: 1xx(临时响应):这些状态码表示服务器正在处理...
301(永久移动)和302(临时移动)用于页面迁移,301是永久性重定向,搜索引擎会更新索引,而302则是临时重定向,搜索引擎仍会抓取原始URL。303(查看其他位置)和307(临时重定向)类似于302,但推荐使用GET方法...
302(临时移动)与301类似,但只是临时的重定向。303(查看其他位置)建议请求者使用GET方法到新位置获取资源。304(未修改)表明资源自上次请求后未发生变化,服务器不会返回资源内容,以节省带宽。305(使用代理)...
- **303 See Other**:与301/302类似,区别在于原本通过POST请求的资源现在应通过GET方式获取。这是HTTP 1.1新增的状态码。 - **304 Not Modified**:客户端请求的资源自上次请求以来未发生变化,因此返回此状态码来...

服务器接收到请求后,返回一个HTTP状态码302(临时重定向)或301(永久重定向),并附带一个新的URL。客户端接收到这个响应后,会自动发起一个新的请求到新的URL,这意味着浏览器的地址栏会显示新的URL。由于是两个...
#### 三、301重定向与302重定向的区别 - **301重定向**表示网页已被永久移动,搜索引擎会更新索引,并将权重传递给新地址。 - **302重定向**通常表示网页暂时性移动,搜索引擎会继续索引原网页,而不更新其索引信息...
HTTP状态码是网络通信中非常重要的元素,它们用于表示服务器对客户端请求的响应状态。HTTP状态码由三位数字组成,并附带一个简短的原因短语,帮助开发者理解服务器的响应情况。以下是关于服务器返回的十四种常见HTTP...
例如,状态码301(永久移动)表示请求的资源已被永久转移到新的URL,而302(临时移动)则表示资源临时移到了新的URL。 4xx (请求错误):这些状态码意味着请求中有问题,阻碍了服务器的处理。例如,400(错误请求)...
#### GET与POST请求的区别 1. **数据传输方式**:GET请求通过URL传递参数,而POST则通过请求体传递数据。 2. **数据大小限制**:GET请求由于依赖URL,因此受到URL长度的限制,通常小于2KB;而POST请求没有此限制,...
