A Note on Retrieval Using Hierarchical Structure of Web Video Groups: Evaluation of Effectiveness through a Visualization Interface

Abstract

We have previously proposed a Web video retrieval method using hierarchical structure of Web video groups, which are sets of Web videos with similar topics. Although conventional works verified the eectiveness of the retrieval method on the basis of an evaluation metric for clustering, verification for the usability such as degree of users’ satisfaction was insufficient. Therefore, this paper newly proposes a visualization interface of the retrieval method, and enables a subject experiment that assumes real-world deployment. By the experiment, the usability of the retrieval method can be confirmed.
