Abstract: With expanding of query requirements, event-relative semantic has appeared for data stream applications. This paper builds a simple but effective event-driven data stream model EQM based on event semantics and features over data stream. Furthermore, some improved approaches over event detection and queries as well as relative efficiency evaluation are discussed. Experiments show that our approaches gain better performance than available data stream model and processing approaches as far as event-relative problem is concerned.
