A framework for classification of meeting videos is proposed in this paper. We define our framework consisting of a four level concept hierarchy having movements, events, behavior, and genre; which is based on the meeting ontology and taxonomy. Ontology is the formal specification of domain concepts and their relationships. Taxonomy is the general categorization based on a class/subclass relationships. This concept hierarchy is mapped to an implementation of Finite State Machines (FSM) and Rule-based system (RBS) to classify the meetings. Events are detected by the FSMs based on the movements (head and hand tracks). Classification of the meetings is performed by the RBS based on the events, and behaviors of the people present in the meetings. Our framework is novel and scalable, capable of adding new meeting types with no re-training. We conducted experiments on various meeting sequences and classified meetings into voting, argument, presentation, and object passing. This framework has applications in automated video surveillance, video segmentation and retrieval (multimedia), human computer interaction, and augmented reality.
