Hi, I posted the follwoing request to the comp.ai, and I have received more requests than replies. A summary of what I have got is attached. My original message was: >I am looking for machine learning tools for building up a classification >system. I heard that most successes in inductive construction of >classification systems (and expert systems) are derived from Quinlan's >ID3. If you have used such commercially available packages, >please e-mail me at your earlest convenience: >1. Your experience with the software. The domain you have worked on. > Did the tool help greatly in the system development? >2. Which company sells the package, how much? Their address and/or > phone number.

Prof. Quinlan is selling under license a classification package (7000 C lines) for about 80 dollars. Easy to install. Well done. Numerous features. You can contact him by mail at "quinlan@cs.su.oz.au" for more information.
