- 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.
