Recently we completed the installation and training of an open source Bayesian classifier to replace a rule-based approach to manage forum spam. In a nutshell, we found the rule-based approach was highly prone to both false positives and false negatives; however, a statistical approach using a Bayesian approach has turned out to be far superior.

There is quite a lot is happening in the world of complex event processing. Interestingly enough, the people and the companies advancing processing complex events are not calling what they are doing “CEP the Buzzword” we read about in the press or that a handful of “pioneers” claim make them modern-day CEP “experts”.
The companies processing [...]

In my earlier post today, A Review of Zabbix - Zabbix Rules! (Part 2) I used the term “event precursor.” Afterwords I thought “this is a nice event processing term, I wonder who used it before me?”
So, I did a bit of Googleing around and came up with this excellent paper where the term “event [...]
