Semantic Event Extraction from Basketball Games using Multi-Modal Analysis

In this paper, we present a novel multi-modal framework for semantic event extraction from basketball games based on Webcasting text and broadcast video. We propose novel approaches to text analysis for event detection and semantics extraction, video analysis for event structure modeling and event moment detection, and text/video alignment for event boundary detection in the video. Compared with existing approaches to event detection in sports video which rely heavily on low-level features directly extracted from video itself, our approach aims to bridge the semantic gap between low-level features and high-level events and facilitates personalization of the sports video. Promising results are reported on real-world video clips by using text analysis, video analysis and text/video alignment.
