Re: significant differences
A rather trivial point, but the UNIX "diff" command has
a "-b" option which causes it to ignore differences which
are only in the blanks and tabs (whitespace).

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.
