Event description, scene analysis, cognitive vision, concept structure,attention
Automatic detection and description of events, particularly human behaviour, is one of the most challenging issues, as event interpre- tation is highly dependent on the target of attention, which is not uniquely specified. To tackle this problem, we propose the concept of a “cognitive ontology as a framework for a system that can automatically decide the attention focus and describe the events. A cognitive ontology is structured with conceptual units which are Entities and Relations, and these units enable robot endogenous at- tention fixation and jumps based on a networked cognitive ontology. In addition, we introduce exogenous attention fixation based on how the observed targets differ from a predicted pattern. In this process, the corresponding target of attention is updated and assigned to an event description buffer that consists of two Entities and one Rela- tion. In this paper, we have developed and experimented with this holistic event interpretation process taking into account endogenous attention, exogenous attention and determined event description.
