摘要: 为了克服PageRank在搜索过程中重复性地把当前受欢迎的网页放在搜索结果的首要位置,而不受欢迎的网页被大多数用户忽略的问题,采用了一种改进的评估函数及有效的用户模型,获得了一个新的PageRank优化算法。实验结果表明,该算法达到了较好的公平性。

关键词: PageRank算法, 评估函数, 用户模型

Abstract: Search engines repeatedly return currently popular pages at the top of search results, popular pages tend to get even more popular, while unpopular pages get ignored by an average user. In order to escape from this problem, an improved ranking function and effective Web user model are employed, and a New PageRank Optimization(NPRO) algorithm is provided. Experimental data show that the provided algorithm can attain unbiased Web ranking.

Key words: PageRank, ranking function, user model
