I am looking for good reference material on building expert systems using frames in Lisp. The environment will be GCLISP. What I need is a good basic understanding of how to chain through the frames and do the pattern matching. I am new to this, so any good pointers will be appreciated.

We conducted six member projects on the building of MARGIE. This Margie took an english story and converted it into "Frames" where then it was pattern matched against set scripts (senerios or events). From this matching the system could then construct an infered sequence of actions form the given. It took about six months to develope. The book we used as an outline, which gave us a firm grasp on the basics of the entire system, was Roger Shanks book named "INSIDE COMPUTER UNDERSTANDING." It gave us a great lead. We did vary to a certain extent in actual developement, but the basics are still there. I would be glad to aid you in any way for those further developements, because they provided a more natural way of demonstrating working cognitive structures. (In theory of course.) I must say that the book is a must to get you going. Another great lead in this search would be to contact George Stockman, Prof. at Michigan State University. He was the developer of our course project and is a biggie on frame representation of knowledge and expert systems. (He taught me every thing I know). Please contact me if you need any assistance at all. Dave Bigelow (summer hire and damn well worth it!)
