摘要：The progress of digitization at broadcasting stations enables intellectual production of high-quality content from video materials. Metadata plays an important role in describing the semantics of multimedia content, which helpssemantic structuralization of video materials. We developed an annotation method for video content based on the concept of the semantic graph, which enables semantic queries on video content. The method incorporates three ideas : metadata on video scenes, time-series of video scenes, and semantic links to external data. In the method, metadata are provided by human annotations. Human annotation is one of the practical ways based on an actual situation in TV productions. We also demonstrated its application using a real baseball game content, and evaluated the proposed annotation method.
