基于语义网的自动问答技术研究项目源代码

Section 1.简介
下面是项目的演示视频：DEMO系统演示视频(双击全屏观看）
演示视频
下面是对整个项目的总结文档：基于语义网的自动问答系统实现
运行这个文件需要安装mysql+php+apache,此外还需要将rdf数据发布成为关联数据形式（利用Pubby+fuseki，参加我以前的文章）
整个程序的目录如下
本程序只是为了做出demo系统，所以不讲究格式语法框架效率之类的细节问题，实现的方法也比较笨。因为这个项目还没有结束，后期我会继续更新，可能会有java做出更加合理且实用的东西，敬请期待。代码很杂乱，有耐心的可以交流。
下面我将所有的代码都贴出来，并提供下载链接。

本代码的主要功能是实现主页面的显示。
