INTRODUCTION
This is a frame-based expert system shell, as discussed in the
Sept. '90 Expert Toolbox in AI Expert Magazine.
The purpose of this shell is to demo a frame-based shell. Therefore
only a minimal set of features are included. In addition, the shell
prints out the final state of its knowledge base after a session --
something that you wouldn't do for an end user. (Note: Don't worry
if some of that rushes off the screen - it also goes to the LOG.LOG
file).
HARDWARE REQUIREMENTS
The expert system requires an IBM-PC, XT, AT, 386 or PS/2 compatible
machine. The minimum amount of RAM memory required for
the expert system is about 384K, but more is better.
INSTALLATION
This program comes in a self-dearcing file. Copy the file
to a subdirectory and type the file name (without extension)
into DOS.
ALLOCATING FILES AND BUFFERS
The expert system is written in Prolog, which uses a number of files
internally. Therefore, to guarantee that the system does
not run out of file buffers during a run of The expert system, it is
best to include the following commands in your CONFIG.SYS
file.
files=20
buffers=20
NOTE: The actual number of file buffers used is around 10,
so you can probably get by with numbers smaller than 20 in
these commands.
RUNNING THE PROGRAM
Type to DOS either

THE KNOWLEDGE BASE FILE
SITE.KB is an example knowledge base for this expert system shell.
Both the rules and the goal are frames, in standard Prolog frame
notation.
THE LOG FILE
Anything you see on the screen during a run of the program also
appears in the LOG.LOG file. This lets you review the behavior of
the expert system shell.
