NicoScene: Video scene search by keywords based on social annotation

Abstract

As there are increasing needs to view a huge number of videos on the Web in short time, the video summary technology is actively investigated. However, there exists trade-offs of costs and precision of summaries. In this paper, we propose a system called NicoScene to search desirable scenes from the videos provided in a video hosting service called Nico Nico Douga. We use the feature of the service in which we can attach comments to videos and treat the comments as social annotation. By some experiments, we demonstrate the advantages of NicoScene in particular the search precisions. © 2010 Springer-Verlag.
