因为现在网络上关于web爬取的理论及技术已经较为成熟，所以在本文中并没有特意去编写程序，而是借助于现有的软件来实现观点爬取。

Because the network on the web crawling theory and technology is more mature , so in this article did not go out programming , but the means to achieve the current viewpoint crawling software .

主题爬取相较于一般的web爬取，主要区别在于它的页面相关性和链接相关性，而这两个相关性又是主题爬取的关键所在。

Compared to the general theme of web crawling , the main difference of subject crawling lies in its pages relevance and links relevance , while the relevance of these two is the key theme of crawling .

所以本文在提出主题爬取的观点之后，对页面相关性和链接相关性也进行了一下详细的介绍，并且运用Java技术进行了一个简单的实现。

The result of the experiment shows that the crawler system has a good performance and can automatically collect information accurately .

需求反馈的实现上，还需要根据不同的观点爬取目标来分别设计不同的反馈途径。

Feedback needs to achieve , also need to take different points of view target to climb different feedback channels were designed .

但从实际结果来看相对单纯的人员爬取数据，效率高整体质量也相当不错。

However , the actual results , relatively simple person crawling data , the overall quality and high efficiency is also quite good .

在主题爬取的实现上，应该寻求更加切实可行的实现方法，争取能够编制出结构完善且功能强大的软件。

In the realization of the subject crawling , should seek to achieve a more practical approach to preparing for a structured and powerful software .
