Abstract
Reasoning systems tapping into the physical world often have to deal not only with temporal relations but also with spatial relations while performing complex event processing. Spatio-temporal relations are a special kind of relations as all events are intertwined via these relations. Treating spatiotemporal relations similarly to other relations will have a significant negative impact in the system performance while reasoning. Therefore, spatio-temporal relations have to be treated differently. JBoss Drools 6 is a production rule system which provides facilities for complex event processing with temporal relations but currently lacks capabilities for spatial reasoning. In this paper, we introduce a mechanism which provides such a capability. The mechanism is implemented directly in the events therefore no Drools source code modifications are necessary. The feasibility of such a mechanism is evaluated from the performance viewpoint. With our spatial reasoning implementation in place, Drools can be claimed capable for spatio-temporal complex event processing.
