工作流程图安排

目标

  • 了解学习目标 利用LDA主题模型结合SVM分类算法,实现文本小实验
  • 安装python64位 安装相关Python包,实现jieba分词

data precessing and built corpus

完成语料库的建立和字典的建立

  • 将result.txt处理成.dict文件
  • 将语料进一步改造成Blei’s LDA-C形式的语料库

主要使用gensim这个库

TF_IDF, LDA

探究TF_IDA的使用

  • 基于gensim.models中 TF_IDA的调用

探究LDA模型

  • gensim中的LDA主题模型可以傻瓜式调用(主题的权重值可以是0)

SVM

了解svm分类算法 应用一下svm模型
