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.

Lately I have been busy with a web-based geo-targeting project. For those of you not familiar with geo-targeting, the deeper you get into geo-targeting, the more you realize how important and interesting it is. Geo-targeting is used for fraud detection, personalization, ad-targeting, content-delivery, and more. In addition, the same basic concept is used [...]

The Amazon Elastic MapReduce team has a sample application, CloudFront LogAnalyzer, designed to analyze Amazon CloudFront access logs. This tool provided users with the power of Amazon Elastic MapReduce to quickly turn access log data into actionable intelligence.
Access logs are activity records about all requests delivered through Amazon CloudFront and contains a valuable set [...]

In A Review of Zabbix - Zabbix Rules! (Part 1) we provided a brief introduction to Zabbix in the context of network and security management. In this post I will discuss Zabbix as an event processing platform.
Zabbix is like most event processing platforms. Zabbix provides both agent-initiated events as well as server-requested events. [...]

When discussing CEP and EP, someone recently blogged:
“There is even one person who declared a full fledged cyber war on anybody who uses the term “complex event processing” not in what he believes to be the original intent of past DARPA project in the area of security and military operational applications.”
Actually, I think that blogger [...]

I often wonder why there is tension in the world of CEP about the complexity of the events and the required processing to identify complex events. Then, about a month ago, I was helping a friend with her masters degree thesis. She is about to graduate with her masters degree in international business and is [...]

Recently Peter Lin was kind enough to stop by and post this comment to our post, CEP Software Saves the Universe!
Here’s my [Peter Lin's] bias perspective as a user and developer of expert system shell[s]. A business rule engine, expert system shell or CEP engine at best provide[s] a foundation for creating an expert system, [...]
