摘要
针对HITS算法中容易出现"主题漂移"的问题,提出了一种新的主题发现算法.首先从对权威度贡献大小的角度出发,将链接分为两类,首尾节点均在根集中的链接为第一类,赋予较高的权重,同时通过分析链接锚文本来调整另一类链接的权重.通过这种方法,有效地改善了主题提取的质量.
According to the problem that the Topic Draft is easy to occur in the HITS algorithm, this paper presents a new topic search algorithm. First, based on contribution for authority score, all hyperlinks were divided into two groups. One group including the links whose first node and last node belong to Root Set was endowed with higher weight. And through analyzing the hyperlink anchor, the weight of another group was adjusted. An example demonstrating its capabilities was provided.
