Learning Rich Semantics from News Video Archives by Style Analysis C. G. M. Snoek, M. Worring, A. G. Hauptmann In ACM Transactions on Multimedia Computing, Communications and Applications 2006. [bibtex] [pdf] [url]

We propose a generic and robust framework for news video indexing, which we found on a broadcast news production model. We identify within this model four production phases, each providing useful metadata for annotation. In contrast to semi-automatic indexing approaches, which exploit this information at production time, we adhere to an automatic data-driven approach. To that end, we analyze a digital news video using a separate set of multimodal detectors for each production phase. By combining the resulting production-derived features into a statistical classifier ensemble, the framework facilitates robust classification of several rich semantic concepts in news video; rich meaning that concepts share many similarities in their production process. Experiments on an archive of 120 hours of news video, from the 2003 TRECVID benchmark, show that a combined analysis of production phases yields the best results. In addition, we demonstrate that the accuracy of the proposed style analysis framework for classification of several rich semantic concepts is state-of-the-art.
