Soccer highlights generation using a priori semantic knowledge

This paper argues that an a priori semantic background knowledge base is essential for automatic audio-visual summarisation. We demonstrate experimentally that content-based metadata are relevant to the selection of events to include in soccer highlights. However they do not provide the necessary context to select all interesting information to present to the viewer. Supported by preliminary results from an ongoing knowledge elicitation study, we also contend that summarised information presented within a narrative structure is more pleasing to the viewer.
