基于改进的PageRank的网页信息可信度评估方法

摘要

To solve the problem of measuring Web information's credibility, a method for computing Web information's credibility was proposed. This method not only considered the interactive structure between Webs, but also took into account semantic relation between the Web information. As the interaction between Web information possessed different release time, in order to reflect time factor, the time decay function was introduced in computing. Experimental result showed that the proposed method was feasible and effective, and could provide Web information with higher credibility for users.%提出了一种基于改进的PageRank的网页信息可信度评估方法,该方法既考虑了网页间的交互结构,也考虑了网页信息主题间的语义关系.由于网页信息内容具有不同的发布时间,在进行可信度评估过程中,还引人了时间衰减函数,从而反映时间这一要素的影响.实验结果表明,所提出的可信度评估方法是有效的,可以为用户提供可信度较高的网页.
