CORE+: A Complex Event Recognition Engine in C++

Complex Event Recognition (CER) refers to the activity of analyzing streams of continuously arriving event data, to recognize collections of events that satisfy user-defined patterns. CER is known to be computationally challenging, since it requires maintaining a set of partial matches, and this set quickly grows super-linearly in the number of processed events. In this paper we demonstrate CORE+, a mature COmplex event Recognition Engine that circumvents the super-linear partial match problem. CORE+ is based on a research prototype named CORE; we demonstrate the new features and capabilities that make CORE+ a release version of CORE.
