- Mark Derthik, Michael G. Christel, Alexander Hauptmann, D. Ng, S. Stevens, H. Wactlar. 2003. A Cityscape Visualization of Video Perspectives. Abstract: CMU’s Informedia project has collected and automatically processed a multi-terabyte video corpus containing 8 years of CNN broadcasts and other video sources [5]. Previous work has demonstrated multi-modal querying by text, image, time, and location, and the ability to summarize a single document or a set of documents matching a query. We now plan to organize the corpus or a subset along multiple dimensions, or perspectives, adding relevant background material, significantly expanding and accelerating the viewer’s comprehension and integration of knowledge. A perspective can provide factual background information, a history of an issue, the view of a biased source, a technical or medical perspective, or any of dozens of others. This abstract proposes a cityscape metaphor for organizing visual context in terms of perspectives.
