This is a call for help... I am looking for advice or comments from anyone who has experience in developing expert systems using model based reasoning or knowledge representation. I am currently developing a medical diagnostic expert system and would like to use model based reasoning. I intend to use either an object-oriented ES shell like KAPPA from IntelliCorp or just an object-oriented language like C++, Smalltalk or Actor. If you have experience or comments on this area, please respond by email. All replies will be gratefully received. Thanks, Cindy Sarmiento Univ. of South Florida (in Tampa, not Miami as many believe)

(i can't remember the name of the book, but you should have no problem finding it with deKleer's name.) the reading there include (i think) one paper by kuipers who has applied hard core naive physics ideas in the medial area. (his domain was rhenal failure if i remember right.) good luck. its a very interesting area to be working it. ---jon---

Cindy, your return E-mail address is incomplete, so I am posting my reply...
I have used Smalltalk. Model-based reasoning is pushing the state of
the art. Still, I have built some models in Smalltalk, and used them
to evaluate diagnostic reasoning techniques. Please E-mail me for
more information.

KARDIO: A Study in Deep and Qualitative Knowledge for Expert Systems. The MIT Press, 1989. It incorporates a deep model of the heart which simulates its electrical activity, represents the model at several levels of abstraction, and automatically derives an efficient, surface diagnostic rule-base.

A couple shells are available for model-based reasoning: IDEA from AI Squared Inc. 508-250-4000 POINTER from ARINC Research Corp. 301-266-4650 I have not worked with either product, but I have seen a demo of an application done with POINTER and was impressed with its execution speed. Some model based reasoning schemes execute so slowly that it would be a knockout factor for the application from the user interface/friendliness viewpoint. -- Mott Given @ Defense Logistics Agency Systems Automation Center, DSAC-TMP, Bldg. 27-1, P.O.

Do check out the proceedings of the model-based reasoning workshops held at the past few AAAIs and IJCAIs.
