[comp.lang.lisp] A Small Expert System???

A SMALL EXPERT SYSTEM??:
	I am C lover and learning Lisp&AI now.After I finished some
practices on the programming(including a integrtor and derivitive
solver), I am suggested to practice to write expert system. But I 
was stuck for some time.
	In order to start, I would be very happy if someone is very
kind to give some suggestions and a rarely small expert system source
code in LISP (rule-based). It will include the inference engine, know-
ledge base . SPECIALLY I would hope to see the reflection of the con-
fidence level(Or constrain propagation?). Some example like, "He would
mean this(0.6)" if system has no sure solution. Therefore I can have 
a whole picture about how to do it.
	Thank you very much.
