Begin developing the knowledge base by defining goals for the expert
system consultation (continued): |
 |
Step 3: Document the possible values
each of the goal attributes defined in step 2 could have and consider
the number of recommendations you will want to seek to represent a solution.
In this example, you would need to make lists of all possible values of
the problem and recommended action attributes. You would
also need to consider whether you would stop the consultation as soon
as one value of each goal is found, or try to find more than one value. |
|
Step 4: If you cannot do steps 1, 2 and 3,
STOP! You need to
rethink the problem. You may not have an appropriate problem for
an expert system, or you may not yet understand the problem environment
sufficiently to formulate a solution as a rule-based expert system.
Rule-based expert systems implement goal-seeking behavior, so you must
be able to define the goals before you can begin building such a system. | |

Once the goals are defined, it is time to begin
formulating the rules that will allow recommendations to be made. |
