ETALIS: Rule-Based Reasoning in Event Processing

摘要: Complex Event Processing (CEP) is concerned with timely detection of complex events within multiple streams atomic occurrences, and has useful applications in areas including financial services, mobile sensor devices, click stream analysis so forth. In this chapter, we present ETALIS Language for Events. It an expressive language specifying combining events. For provide both a syntax as well clear declarative formal semantics. The execution model the based on compilation strategy into Prolog. We implementation language, experimental results our running prototype. Further on, show how logic rule-based approach compares non-logic respect performance.
