How to Contribute to the CEP Community – Use Cases
There are a number of folks interested in CEP and many of them unsure where to get started. We discussed this recently in the Yahoo! CEP-Interest eGroup before we got sidetracked with the standard data stream processing obstructionism by our colleagues at Aleri Labs, who continue to try to redefine CEP in their view of [...]

IBM has integrated Coral8 into its WebSphere RFID Information Center product; and Coral8 is providing a free deployment license to all IBM customers using the new version of WebSphere RFID Information Center. In a similar strategy that Esper and BEA are following, Coral8 believes that a “give away” strategy will help boost their sales and [...]
Read moreBEA’s Event Server and Eclipse
Speaking of BEA, I really enjoyed this short BEA screencast showing how to change event stream processing rules and deploy the changes on-the-fly, in the their Eclipse design-time environment. This screencast shows an impressive Eclipse administrative interface to hot deploy their event server applications. Impressive. Great job David Reed of BEA!
Read moreBEA Event Server Screencast: Airport Lost Baggage Use Case
BEA has a nice screencast that demonstrates event processing in airport operations. Their screencast illustrates how WebLogic Event Server can be configured to detect missing events, a requirement often discussed in many CEP and ESP applications (not unique to BEA). The demo uses SL’s RTV, also used by TIBCO and Progress Apama, as a business [...]
Read moreStandard Data Sets for CEP/IDS Evaluation
We have been discussing standard data sets for CEP on CEP-Interest lately and have introduced the topic of “event cloud generation” here. For those interested in applying CEP to intrusion detection, there is an evaluation dataset available from MIT. “These evaluations measured probability of detection and probability of false-alarm for each system under test. These [...]

BEA has made their WebLogic® Event Server 2.0 documents available in both HTML and PDF format to the general public. This is good news for everyone. Currently there are 6 PDF files: Getting Started With WebLogic Event Server Creating WebLogic Event Server Applications WebLogic Event Server Administration and Configuration Guide EPL Reference Guide WebLogic Event Server Reference [...]
Read moreClouds (Partially Order Sets) – Streams (Linearly Ordered Sets) – Part 2
Originally posted in Yahoo! CEP-Interest Here is my follow-up note on posets (partially ordered sets) and tosets (totally or linearly ordered sets) as background set theory for event processing, and in particular CEP and ESP. In my last note, we discussed posets and tosets in the context of ESP (tosets) and CEP (posets) and we [...]
Read moreClouds (Partially Order Sets) – Streams (Linearly Ordered Sets) – Part 1
Originally posted in Yahoo! CEP-Interest We read interesting discussions in the CEP and ESP market regarding terms like “clouds” and “streams”. Sometimes we observe folks talking about these terms in context of “processing time”, for example, reordering events as part of computational event processing. A closer examination of posets and linearly ordered sets leads to [...]
Read moreBending CEP for Rules
I think James Taylor and my good friend Paul Vincent should be mindful not to reduce CEP (accidentally or intentionally) to rule-based systems, and broaden their perspectives and blog entries. In the original work on CEP by Dr. Luckham, the point of CEP is to solve complex problems in many problem domains, many require backwards [...]
Read moreCEP Soapbox: Moving from Marketing to Modelling
Many of the folks in the event processing community are my dear friends, so I hesitate to stand up on my vulnerable soapbox and speak a piece of my mind. If you would be so kind to permit me to get on my soapbox without naming names or providing links, that would be much appreciated. [...]
