Java版PageRank及網站收錄情況查詢代碼

系統 1884 0

在Google這個由10的100次方得名的站點中，各種評估網站的算法層出不窮，而PageRank即是其中之一。

Google的PageRank根據網站的外部鏈接和內部鏈接的數量和質量倆衡量網站的價值。PageRank背后的概念是，每個到頁面的鏈接都是對該頁面的一次投票，被鏈接的越多，就意味著被其他網站投票越多。這個就是所謂的“鏈接流行度”——衡量多少人愿意將他們的網站和你的網站掛鉤。PageRank這個概念引自學術中一篇論文的被引述的頻度——即被別人引述的次數越多，一般判斷這篇論文的權威性就越高。

通常情況下講，原創內容越多的站點，PageRank越容易提升，反之則相對比較困難，PageRank最大上限值為10。在Google的評估中，能上10的網站真可謂鳳毛麟角，即使算上Google，能成就PageRank 10這“偉業”者，望眼環球也不足40家。一般來說，個人站點評估值4即辦的不錯，商業網站到6以上便算步入正軌了。

網上雖然有不少現成的查詢器及源碼，但是光用別人的畢竟不符合程序員風格，所以今天自己用Java重造輪子又寫了個PageRank查詢實現，捎帶著把一些常用搜索引擎的網站鏈接及反向鏈接查詢也加上了。

源碼如下：
