Conceptual Description
Among thousands of incoming events, a monitoring system may for instance receive the following three from the same source:
- church bells ringing.
- the appearance of a man in a tuxedo with a woman in a flowing white gown.
- rice flying through the air.
From these events the monitoring system may infer a complex event: a wedding. CEP as a technique helps discover complex events by analyzing and correlating other events: the bells, the man and woman in wedding attire and the rice flying through the air.
CEP relies on a number of techniques, including:
- -Event-pattern detection
- -Event abstraction
- -Modeling event hierarchies
- -Detecting relationships (such as causality, membership or timing) between events
- -Abstracting event-driven processes
Commercial applications of CEP include algorithmic stock-trading, the detection of credit-card fraud, business activity monitoring, and security monitoring.

Famous quotes containing the words conceptual and/or description:
“Analyze theory-building how we will, we all must start in the middle. Our conceptual firsts are middle-sized, middle-distanced objects, and our introduction to them and to everything comes midway in the cultural evolution of the race.”
—Willard Van Orman Quine (b. 1908)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
