Abstract: Considering the problems aroused by the traditional association rules presentation formalizing approaches which are powerless to demonstrate the domain knowledge,especially not conducive to express the relationships of items and the implicit information of rules,this paper introduced a novel methodology for the knowledge representation of association rules based on conceptual graphs．The proposed methodology consists of schema definition and schema parse,and these two schemas can effectively parse the association rules into the conceptual graphs representation formalism by using conceptual graphs．At the end ,this paper illustrated the advantages of the new method with the help of experimental data obtained from demographic data of a province,and the realistic application analysis and experimental results turn out that this methodology has much excellent representation effects for the demographic domain knowledge.
