Science Development Program AI/Education Seminar Friday, 1 August 10:30am From Guidon to Neomycin and Heracles--Viewing Knowledge Bases as Qualitative Models Dr. William J. Clancey Stanford Knowledge Systems Laboratory Computer Science Department 701 Welch Road, Bldg C Palo Alto, CA 94304 Beginning with early attempts to improve MYCIN's representation of knowledge for use in teaching, we have followed the approach of decomposing knowledge from how it is used, abstracting knowledge structures and reasoning procedures, and formulating an increasingly more general understanding of what knowledge engineering and knowledge bases are all about. In NEOMYCIN, medical knowledge and diagnostic procedure are separately represented in well-structured languages to facilitate explanation and student modeling. In HERACLES, this knowledge base is viewed as a classification model of some physical, cognitive, or social system that is heuristically related to some design, modification, prediction, or control action. That is, we view the knowledge base as a qualitative model of some system in the world, designed with practical engineering value in mind. From this perspective, the "diagnostic strategy" of Neomycin is a general inference procedure that describes memory activation and search for constructing a situation-specific model. This talk will review the development of NEOMYCIN from GUIDON and summarize the generalizations that we are now exploiting in our development of the HERACLES shell and GUIDON2 teaching programs. ------------------------------ END OF IRList Digest ********************
