Java版PageRank及网站收录情况查询代码

在Google这个由10的100次方得名的站点中，各种评估网站的算法层出不穷，而PageRank即是其中之一。

Google的PageRank根据网站的外部链接和内部链接的数量和质量俩衡量网站的价值。PageRank背后的概念是，每个到页面的链接都是对该页面的一次投票，被链接的越多，就意味着被其他网站投票越多。这个就是所谓的“链接流行度”——衡量多少人愿意将他们的网站和你的网站挂钩。PageRank这个概念引自学术中一篇论文的被引述的频度——即被别人引述的次数越多，一般判断这篇论文的权威性就越高。

通常情况下讲，原创内容越多的站点，PageRank越容易提升，反之则相对比较困难，PageRank最大上限值为10。在Google的评估中，能上10的网站真可谓凤毛麟角，即使算上Google，能成就PageRank 10这“伟业”者，望眼环球也不足40家。一般来说，个人站点评估值4即办的不错，商业网站到6以上便算步入正轨了。

网上虽然有不少现成的查询器及源码，但是光用别人的毕竟不符合程序员风格，所以今天自己用Java重造轮子又写了个PageRank查询实现，捎带着把一些常用搜索引擎的网站链接及反向链接查询也加上了。

源码如下：
