Abstract
The present invention extends to methods, systems, and computer program products for altering event lifetimes. Embodiments of the invention include using operators in an event-processing framework (algebra) to shorten (or 'clip') the duration of events. An operator can receive a primary event stream, a clip event stream, and condition as parameters. The operator clips the lifetime of an event in the primary stream to the next event in the clip stream that fulfills the condition. Altering event lifetimes can be used to facilitate cleaning event stream state, converting point events to a continuous signal, and creating and annotating session events.
