On Elephants and Analytics
In On EP and Analytics, good friend and respected colleague Opher Etzion applies the well known metaphor of the big elephant to describe how, if you are observing certain specific domains of a subject, like fraud detection, then your view of the whole elephant is biased by your lack of perspective of the entire big elephant. I am pleased that dear Opher [...]
Read moreTIBCO Leaps Ahead in CEP with Insightful Acquisition
TIBCO Software shows, yet again, why the team in Palo Alto far outpaces the rest of the field with their announced acquisition of Insightful. Everyone who follows The CEP Blog and my vision for the business use of CEP understands how much energy and passion I have put into explaining why the crude time-series analysis of streaming data cannot possibly [...]
Read moreCapital Market CEP Fantasy Land
In Tech Spending Hit by Subprime Mess, Jeffery Schwartz says, “According to Tabb, spending on development is being refocused on projects that can help firms improve their margins and, not surprisingly, do a better job at risk management. As such, investments in capabilities such as algorithmic trading and complex event processing (CEP) are likely to [...]
Read moreProbabilistic Complex Event Triggering
Here is an interesting paper, Probabilistic Complex Event Triggering, Daisy Zhe Wang, Eirinaios Michelakis, and Liviu Tancau, Computer Science Division, University of California at Berkeley, circa 2005. One of the first things I noticed about the paper was the discussion of probability in the content of complex event processing, including Hidden Markov processes, Bayesian Belief [...]
Read moreMore on CEP Maturity: Capability Versus Reliability
Louis Lovas of Progress Apama wrote a complimentary blog entry on the topic at hand, CEP Maturity Models. In his post, Louis says: “What a CEP platform has tracks independently of what it is capable of doing. ….. What CEP does, is likely what Tim is referring to when he states we’re in the Technology Trigger phase.” [...]
Read moreOn the Maturity of CEP
Deciphering the Myths Around Complex Event Processing by Ivy Schmerken stimulated a recent flurry of blog posts about the maturity of CEP, including; Mark Palmer’s CEP Myths: Mature or Not? and Opher Etzion’s On Maturity. I agree with Ivy. CEP is not yet a mature technology by any stretch of the imagination. In fact, I agree with all [...]
Read moreA Vocabulary of Confusion
The blog post, On Event Processing Agents, reminds me of a presentation back in March 2006, where TIBCO‘s ex-CEP evangelist Tim Bass (now busy working for a conservative business advisory company in Asia and off the blogosphere, as we all know) presented his keynote, Processing Patterns for Predictive Business, at the first event processing symposium. In that [...]
Read morePlease Welcome Dr. Rainer von Ammon to The CEP Blog
Today is an especially joyful occasion on The CEP Blog. I am pleased to announce that one of the world’s top experts on CEP, Dr. Rainer von Ammon, has joined the blog. Dr. Rainer von Ammon is managing director of the Centrum für Informations-Technology Transfer (CITT) in Regensburg. Until October 2005 he was Professor for Software Engineering, specializing in [...]
Read moreKey Indicators (KIs) Versus Key Performance Indicators (KPIs)
SL‘s new web page, Solutions for CEP Engine Users, discusses how CEP is a “technology that is used to help companies detect both opportunities and threats in real-time with minimal coding and reusable key performance indicators (KPIs) and business models.” I agree with SL, but would like to suggest my friends at SL expand the notion of KPIs in CEP [...]
Read moreIBM Will Acquire AptSoft
I was wondering when IBM would actually jump into the event processing market. Well, it was announced today that IBM will acquire Aptsoft, adding an event processing platform to the IBM WebSphere porfolio. IBM will also gain AptSoft’s event processing reference customers. This was a smart move by IBM. Oracle is acquiring BEA which uses Esper under the hood, another [...]
