Continuing with our discussion on Complex Systems and CEP, let’s turn our attention, monentarily, to more scientific, or perhaps philosophical, discussions. Let’s review a bit of chaos theory via the Lorenz effect and talk about the “event soup”, a phrase I shamelessly coined in On the Maturity of CEP.
Edward Lorenz was using a computer model [...]

Professor Luckham wrote about CEP and the future of global Air Traffic Control (ATC) in The Future Event Driven World: Global Air Traffic Management. One of the first commercial applications of complex event processing was in the early 1960s in the field of commercial aviation, for example see the history of Air Traffic Control.
Although experimental [...]

A complex system is defined as a system composed of related components that as a whole exhibit one or more properties not obvious from the easily observed properties of the individual parts. This is certainly true of the CEP notion of the “event cloud” in network systems. A modern energy or telecommunications network is [...]

Opher Etzion responds to the onging confusion with On basic classification of terms. First of all, there has been confusion in the CEP/EP community since the term “CEP” was coined, so the confusion is nothing new. Second, one of the main sources of confusion is the Event Processing Technical Society (EPTS), chaired by Opher. The [...]

Detection experts understand that the optimal detection design and architecture is generally a combination of both signature and anomaly detection engines. In event processing, signature detection involves the real-time pattern matching analysis of events. A core advantage of signature detection is that basic pattern matching models are easy to understand and develop [...]

My apologies for not discovering the error sooner, but for most of November our RSS feed was broken. The problem was an embedded object, which I have deleted. I think the problem has been fixed; however, if you find any additional problems with our RSS feeds, please let me know.

Just as I was starting to worry that complex event processing community has been captured by RDBMS pirates off the coast of Somalia, I rediscovered a new core blackboard architecture component, Hadoop.
Hadoop is a framework for building applications on large commodity clusters while transparently providing applications with both reliability and data motion. Hadoop implements [...]

MapReduce is a software framework implemented in C++ with interfaces in Python and Java introduced by Google to support parallel computations over large (multiple petabyte) data sets on clusters of computers. The Apache Hadoop project is a free open source Java MapReduce implementation. Mahout is an Apache project, based on Hadoop, with an objective to [...]

Folks are worried about the future of CEP.
Vendors have spun so much misinformation around the term “CEP” that this three letter acronym (TLA) has begun to have little meaning other than to reflect a confusing web of solutions overhyped around a few relatively simple stream processing engines, used primarily in financial services. Frankly speaking, in [...]

Paul Vincent of TIBCO wrote an outstanding post, The Value of (Production) Rules … Paul correctly notes:
In summary, of course, event-processing rules, event-driven rules, and rules for business decisions can all overlap, depending on the application.
By coincidence, I was reading an excellent paper recently, Reactive Rules on the Web. In this Springer-Verlag paper, the distinguished [...]
