%X In order to describe certainty factor of rule and proposition,certainty information entropy of rule and proposition was defined.From the perspective of entropy,this article researched uncertainty reasoning in the production rules,established a new Information Entropy Petri Net model(IEPN) based on Petri nets and certainty information entropy,introduced uncertainty knowledge representation and reasoning steps,moreover,analyzed the significance that IEPN reasoning guided the Knowledge Discovery in Database(KD...
