Event-centric composable queue and composite event detection method and applications using ecq

PURPOSE: An event-centered combinable queue, a composite event sensing method using the same, and an event generation sensing system using the same are provided to optimize a computation quantity and the usage quantity of a storage unit. CONSTITUTION: A CLT(Composition Link Table)(110) has basic information configuring the network of event-centered combinable queues. An SIQ(Shared Instance Queue)(120) shares a plurality of sensing sentences. The shared event queue stores past event objects necessary for detection of a composite event. A PCB(Partial Composition Block)(130) stores a middle result that one stored event object satisfies any composite event sensing sentence to a degree.
