A criterion is a premise in a rule, i.e. a logically connected set of relationships between the values of certaincharacteristics and given reference values for those properties.

Examples

In the rule “If Battery Voltage < 11V, then the battery is flat", "Battery Voltage <11V" is the criterion, and Battery Voltage is a placeholder for a value of the property named “Battery Voltage”. When the battery voltage has been measured, application of the rule determines whether or not the battery was flat1Strictly speaking, application of the rule implicitly states that the battery is (or is not) flat at time t without reference to whether t is now or some time in the past, thus obviating discussion about the shift from is in the definition to was in its application. at the time of measurement.

In the rule “If (animal-in-the-window is doggy AND animal-in-the-window has waggly tail) THEN animal-in-the-window IS cute,” there are two criteria (“is doggy” and “has waggly tail”) logically connected by “and”.
