Abstract :
In this paper, we present an exhibition method of hierarchical structure of Web communities using community density for Web video retrieval. In the proposed method, Web communities that are Web video sets with similar topics is hierarchically extracted by using hyperlinks between Web videos and their video features, and density of each Web community is estimated. Then we exhibit the hierarchical structure of Web communities according to the obtained density to users. Since users can grasp detail degree of topics contained in each Web community, the desired Web community can be easily selected for Web video retrieval.
