【摘要】 在基于链接分析的排序算法PageRank分析基础上,提出了一种基于主题相关性和链接权重的Page-Rank改进算法.该方法首先随机选取任一链出页面,通过主题相关性评价算法获得改进的PageRank值,并重新排序.实验结果显示该算法提高了查询速度、查询准确率,并且算法具有良好的稳定性和可扩展性.更多还原

【Abstract】 Based on the analysis of PageRank algorithm and link weighted,a topic weighted PageRank algorithm was porposed.Firstly,any chain randomly selected a page,then,the improved PageRank value was obtained through the topic relevance evaluation algorithm.The experiment shows that this algorithm improves the query speed and accuracy with good stability and expandability.更多还原
