Video Data Mining: Mining Semantic Patterns with temporal constraints from Movies

DOI

Description

For efficient video data management, 'video data mining' is required to discover 'semantic patterns' which are not only previously unknown and interesting, but also associated with semantically relevant events ('semantic events') in movies. In order to extract semantic patterns from a movie, we firstly represent it as a multi-stream of raw level metadata that abstracts the semantic information of the movie. Then, regarding to the temporal characteristic of the semantic event of the movie, we extract sequential patterns which are obtained by connecting temporally close and strongly associated symbols in the multi-stream of raw level metadata. We also propose a parallel data mining method in order to reduce the expensive computational cost. Finally, we verify whether the extracted patterns can be considered as semantic patterns or not.
