Abstract — We present a novel and powerful logical framework for Complex Event Processing (CEP). CEP deals with finding composed events, and has useful applications in areas ranging from agile business and enterprise processes management, financial market applications to active Web and service oriented computation.
Currently many systems for processing events have ad-hoc semantics, usually with an unexpected behavior. We believe formal logical semantics is an important requirement for event-driven reactive systems. On the other hand, many logic-based approaches for CEP (based on formal semantics) fail, due to their inability to compute complex patterns in the event-driven fashion. Our approach enables both logic-based and event-driven complex pattern detection. Moreover, the proposed event-driven backward chaining approach allows for very efficient deductive reasoning of complex events and situations.
We have implemented the logic-based framework for Complex Event Processing. The prototype is called ETALIS, which stands for Event-driven Transaction Logic Inference System. See our demo: http://krake26.perimeter.fzi.de:8080/etalis
