Clustering and Visualizing Audiovisual Dataset on Mobile Devices in a Topic-Oriented Manner

摘要

With the significant enhancement of telecom bandwidth and multimedia-supported mobile devices occupying the market, consuming audiovisual contents on the move is no longer a hype. A lot of telecom operators are now porting traditional TV service to PDAs, 3G cell phones. However, several surveys suggest that direct migration of service from large screen to small screen may not comply with mobile users' consuming behaviors. In this paper, we first elaborate existing surveys together with our survey result to understand consumer interests in terms of consuming audiovisual contents on mobile devices. Based on the findings, we propose a novel solution to help user locate, gather, and cross-relate topics scattered in an array of contents across various domains. A web-based demo application has been implemented for PDA. The system evaluation indicates that this paradigm of organizing and presenting multimedia archives is very welcomed.
