Abstract
This paper deals with composite events in active databases. It describes the syntax and semantics of NAOS composite event expressions. This semantics is based on the semantics of the proposed operators and on the notions of context of detection and validity interval These notions are central especially for event types containing negations and strict disjunctions. The paper also describes the event detection process with is modelized by event graphs.
