Recent development in sensor networks and mobile computing is gaining increasing interest from enterprises. Sensor data services can provide fine-grained information of the physical world and feed the event processing systems where high level business logic is evaluated and coarse-grained business events are derived. However current event processing systems are not user-oriented and take considerable effort to configure and implement mainly because of the granularity mismatch. In this paper, the authors present a intuitive way to model the complex event patterns based on semantic descriptions of sensor service capabilities. Then, they transform the event patterns into stream queries to facilitate an automatic implementation for the event processing system.
