Summary:This paper presents an extraction method of hierarchical Web communities for Web video retrieval. In the proposed method, Web communities containing Web videos whose topics are similar to each other are extracted by using hyperlinks between Web pages including Web videos and their video features. Furthermore, we focus on graph structure of hyperlinks between Web pages including Web videos which belong to the Web communities. Then, by using strongly connected components and betweenness centrality of the graph, hierarchical structure of the Web communities can be estimated. Consequently, users can easily find Web videos including related topics in each hierarchy, and desired Web videos can be effectively retrieved.
