CLIPS - Facts and Rules

Facts and Rules

Like other expert system languages, CLIPS deals with rules and facts. Various facts can make a rule applicable. An applicable rule is then asserted. Facts and rules are created by first defining them, as shown below:

(deftemplate car_problem (slot name) (slot status) ) (deffacts trouble_shooting (car_problem (name ignition_key) (status on)) (car_problem (name engine) (status wont_start)) (car_problem (name headlights) (status work)) ) (defrule rule1 (car_problem (name ignition_key) (status on)) (car_problem (name engine) (status wont_start)) => (assert (car_problem (name starter) (status faulty))) )

In CLIPS, salience allows a user to assign priority (or weight) to a rule.

Famous quotes containing the words facts and/or rules:

    “A pun does not commonly justify a blow in return. But if a blow were given for such cause, and death ensued, the jury would be judges both of the facts and of the pun, and might, if the latter were of an aggravated character, return a verdict of justifiable homicide.”
    —Oliver Wendell Holmes, Sr. (1809–1894)

    “Carnal lust rules where there is no love of God.”
    —St. Augustine (354–430)
