面向校园网搜索引擎的PageRank改进算法

Improved algorithm of PageRank to search engine of campus network

根据校园网的网络结构和资源分布特点,针对经典PageRank算法采用的平分页面自身PageRank值的策略,提出了基于关键词集的网页关联权重分配PageRank值的改进算法.权值由页面间的关联程度和用户的搜索关键词确定,从而提高了校园网搜索引擎的搜索匹配程度和结果页面的排序质量.

According to the structure and resource distribution of the Campus Network and the classical PageRank algorithm to halve the PageRank value of the page itself, an improved algorithm was presented to distribute the PageRank value in light of the link weight of the web pages based on keywords set, the value depends on linking degrees of web pages and on searching keywords set of users, which increases the matching degree of the Campus Network＇ search engine and the taxis quality of the result pages.
