基于Bloom Filter的网页去重算法

现在的互联网中存在网页重复的问题,这些问题将会使数据挖掘,搜索的复杂度加大。现有技术一些不足之处,针对互联网中的重复网页采用基于Bloom Filter的网页去重算法。使用了现有的网页去杂算法,对网页进行预处理,同时利用Bloom Filter结构大大降低了网页去重算法的时间复杂度和空间复杂度。从网页中提炼出表示网页特征的一些长句,从而把网页去重过程转换为一个搜索长句的过程,使用Bloom Filter减小了算法的时间复杂度。

Duplicate Web Page Elimination Based on Bloom Filter

There are many duplicated web pages in the internet, which will make data mining and information retrieval more difficult. In this paper, we analysis the disadvantage of current algorithm, and propose a new algorithm to eliminate duplicated web pages based on Bloom Filter. We use existed refining algorithm to pre-process the web pages, and reduce the running time and stored space using Bloom Filter to process duplicated web pages. This paper use long sentences to represent features of web pages, and change ...
