• Links - Rule Engines

Updated: Dec 5 2008, more links, RuleLab.Net

Note that there is some overlap in the use of the term "rule engine" with pattern matching, text transformation, rendering and other filtering or search engines that have some level of rule capabilities.

RuleLab.Net is closed source, closed license and closed almost everything else, but it has good documentation of its facilities. Also on the plus side of the ledger, it has a hosted solution and is not terribly expensive as these things go.

From the comedy category "What Won't They Grant A Patent On Next", see the IBM Europe Patent on Expert System Inference Engines. One might suspect that the patent was granted in 1969 or maybe even in 1979, but, no, the year was 1989 !!!

As of Fall 2008. there was a well-written document describing the 'patent', but the original PDFs have since disappeared. Maybe IBM changed its mind.
