Events provide the fundamental abstraction for representing time-evolving information that may affect situations under certain circumstances. The research domain of Complex Event Recognition focuses on tracking and analysing streams of events, in order to detect event patterns of special significance. The event streams may originate from various sources, such as sensors, video tracking systems, computer networks, etc. Furthermore, the event stream velocity and volume pose significant challenges to event processing systems. We propose dRTEC, an event recognition system that employs the Event Calculus formalism and operates in multiple computer cores for scalable distributed event recognition. We evaluate dRTEC experimentally using two real world applications and we show that it is capable of real-time and efficient event recognition.
