基于Hadoop的文本分类（1）-文本预处理&文本表示
资源描述一、环境环境：Ubuntu14、Hadoop2.6，Eclipse、NLPIR/ICTCLAS2015等；
二、算法简介：
1、此项目是基于Hadoop2.6进行MapReduce并行开发；
2、此项目是文本分类的文本预处理和文本表示部分，包括分词，去停用词，特征选择和文本表示等（分类算法采用的是随机森林算法，暂时未开放，读者可自行采用Mahout或Weka进行验证）；
3、分词采用的是NLPIR/ICTCLAS2015；文本表示采用的是VSM模型，权重计算采用TFIDF进行文本表示；特征选择采用CHI算法（卡方统计）；
4、关于并行分词环境搭建，可参考我的博客http://www.cnblogs.com/merru/p/4917665.html
5、关于Hadoop环境搭建，可参考我的博客http://www.cnblogs.com/merru/p/4901528.html和http://www.cnblogs.com/merru/p/4905118.html。

Mars_v2
GPU实现的MapReduce framework,对于学习并行编程和cuda平台的编程方面有着极好的参考价值，里面附带论文。用户要求有NViDIA显卡，并且安装cuda编程环境。(We design and implement Mars, a MapReduce framework, on graphics
processors (GPUs). MapReduce is a distributed programming
framework originally proposed by Google for the ease of development
of web search applications on a large number of commodity
CPUs. Compared with CPUs, GPUs have an order of magnitude
higher computation power and memory bandwidth, but are harder
to program since their architectures are designed as a special-purpose
co-processor and their programming interfaces are typically for
graphics applications.)
