摘要

针对多媒体链接在网页中分布的特点,对PageRank、Shark-Search两种典型的主题搜索算法进行相关参数的改进,采用改进后的两种算法从网页内容和网页网页的角度计算多媒体网页与主题的相似度。实验结果表明,改进的Shark-Search多媒体主题搜索算法比改进后的PageRank搜索算法更能有效地提高多媒体主题搜索的效率,同时也更适合网络多媒体资源的主题搜索。

Abstract

Based on the distribution characteristics of the multi-media resources in web pages, the relevant parameters of the two typical search algorithms of PageRank and Shark-Search have been improved, which compute the similarity of the multi-media resources and the subject in the ways of webpage content and web hyperlink. The results show that the improved Shark-Search of the multimedia search algorithm is more effective to improve the efficiency of multi-media topic search, and more suitable for topic search of multimedia network resources than that of PageRank algorithm.

Key words： multimedia; topic search; topic searching algorithm; web spider
