信息化领域热词分类分析及解释

一 项目名称：

信息化领域热词分类分析及解释

二 功能设计：

1) 数据 采集：要求从定期自动从网络中爬取信息领域的相关热
词；
2) 数据 清洗：对热词信息进行数据清洗，并采用自动分类技术
生成信息领域热词目录，；
3) 热 热 词 解释：针对每个热词名词自动添加中文解释（参照百度
百科或维基百科）；
4) 热词 引用 ：并对近期引用热词的文章或新闻进行标记，生成
超链接目录，用户可以点击访问；
5) 数据 可视化 展示：
① 用字符云或热词图进行可视化展示；
② 用关系图标识热词之间的紧密程度。
6) 数据 报告：可将所有热词目录和名词解释生成 WORD 版报告
形式导出。

三 项目源码：

python：
