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.
