Prototypes and Production Rules An Approach to Knowledge Representation for Hypothesis Formation . Janice S. Jul 1979 card 1 of 1

If no CONTROL slot is associated with a prototype, the Interpreter will attempt to fill in values for the prototype components in the order of their Importance measures. When all of the clauses in the CONTROL slot have been executed and the prototype has been instantiated, a decision is madel as to whether the prototype should be confirmed as matching the data in the case. The system then checks either the IF-CONFIRMED slot or the IF-DISPROVED slot to determine what should be done next. Similarly, the ACTION slot specifies stops to be taken for a confirmed prototype during the clean-up stage.
