Concept Algebra and Frame-based Representation for Event and Event Class

The representation of event plays a key role in research of event ontology. In this study, the authors propose a concept algebra and frame-based representation for both event and event class. The advantages of proposed the representation model represent dynamic state changing progress of event, represent relationships between events and construct event class from event instances by operations of concept algebra. Solid definitions and formal representation are given to explain the event model and relationships between events. Case studies demonstrate that the model is effective to represent events and events class.
