Is there any good out-of-the-box Expert System Engine ?

Question

I am looking into Expert Systems - just wondering if there are any good engines (commercial or open) available to facilitate development of a custom expert system (rather than building the whole thing from scratch).

Any help appreciated!

Answer 1

In the business world these are typically called Rules Engines. I've worked with the one from Haley Systems - they were acquired by Oracle last year (http://www.oracle.com/haley/index.html)

Another one that I've seen is ILog

Also, for Net there's one called inrule.

Answer 2

Answer 3

Of course, the classic (free) expert systems shell is CLIPS.
