In Proceedings of the Ninth International Symposium on Temporal Representation and Reasoning(TIME’02) July 07-09, 2002(pp. 61-65).https://hdl.handle.net/10289/1478Event notification services are used in various applications such as digital libraries, stock tickers, traffic control, or facility management. However, to our knowledge, a common semantics of events in event notification services has not been defined so far. In this paper, we propose a parameterized event algebra which describes the semantics of composite events for event notification systems. The parameters serve as a basis for flexible handling of duplicates in both primitive and composite events.application/pdfenThis article has been published in the proceeding of the Ninth International Symposium on Temporal Representation and Reasoning(TIME’02) July 07-09, 2002.
