This paper proposes a hash index for spatiotemporal continuous query processing rules for filtering, classifying, analyzing, and responding to consecutively collected target objects. The Rete technique for improving the performance of rule-based complex event processing shows better performance than the rule interpretation method as it creates a compiled data structure for the rule. This paper proposes a performance improvement method that eliminates the rule search overhead by creating a spatiotemporal index for the Rete nodes expressing spatiotemporal continuity query rules and stabbing the Rete node of the rule by employing hash indexing on the stream data.
