A Simple Situation Model for Complex Events
In an earlier post I explained why situation modelling, and preferable an object-oriented situation model, is one of the key attributes of CEP. Unfortunately, I have yet to find a situation model for complex events, so I offer a few simple baseline concepts here. Your comments and improvements are much appreciated. 1. A situation model [...]
Read moreComplex Events are Composed of Objects Defined by States
Often you will read or hear people talking about CEP and they will define a “complex event” as an event composed of other event-objects. Caution is advised, because a complex event is more than just a simple composite or aggregation of other events. For example, in my earlier post Modelling Situations for Event Processing, we [...]
Read moreModelling Situations for Event Processing
CEP, in a nutshell, is about the real-time detection of business opportunities and threats in cyberspace. Business opportunities and threats are often referred to as situations, so we can simply say that CEP is about the real-time situation detection. We represent situations in the domain of event processing by building and refining models of situations. [...]

After some interesting discussions in the blogosphere, the results of our less-than-scientific Poll: Where is CEP Relative to the Gartner Hype Cycle? are in! Two-thirds of our passionate-about-CEP readers believe that CEP still is in the very early stages of maturity. Only 6% of the those who responded to the poll, conducted from July 3 thru July 12th, voted [...]

Courtesy of Complex Event Processing at Stanford Complex event processing (CEP) is a new technology. It can be applied to extracting and analyzing information from any kind of distributed message-based system. It is developed from the Rapide concepts of (1) causal event modeling, (2) event patterns and pattern matching, and (3) event pattern maps and [...]

This post was originally a comment On CEP Maturity and the Gartner Hype Cycle by Changhai Ke of ILOG. Changhai Ke’s comment was so well written, I have reposted it as a blog entry. The “More” Part of CEP over ESP is Far from Mature By Changhai Ke, ILOG An EDA and CEP must be understood as 2 [...]

In Recent Buyouts, Marc Adler of Citigroup blogs “Despite what the various pundits of the CEP world say, I still think that analytics are an integral part of the CEP stack.” Mark also says something else I agree with, “… [TIBCO] Business Events [ ... is ...] a more workflow-oriented product, something that you would NOT use to [...]
Read moreThe Grammar of Complex and Intelligent Events
Folks defining CEP, and now this new term IEP, have been very passionate over the past few years that “Complex Event Processing” means the Processing of “Complex Events” not the “Complex Processing” of Events. Grammatically speaking, it follows that Complex is an adjective describing a noun, Event; and Processing is a verb. Complex events are defined by the same [...]

Fellow blogger Opher Etzion, replies to On Elephants and Analytics with On Unicorn, Professor and Infant. Opher is kindly giving us another metaphor to consider, the Infant and the Profession, since we are both big fans of big gentle elephants, babies and our universities. Opher and I agree that Infants are not Professors, and we also agree that CEP is in [...]
