Abstract: Considering the problems aroused by the traditional association rules presentation formalizing approaches which are powerless to demonstrate the domain knowledge,lack of displaying multi-schema association rules of one to one,one to many,many to one,many-to-many,and especially ignoring the sharing knowledge of discovering results,this paper proposed a novel knowledge representation method for showing multi-mode association rules based on Vis-Meta graph.Firstly,it gave the relevant definitions of Vis-Meta graph and Vis-Meta graph presentation method of association rules,then introduced the conceptual relationship in Vis-Meta graph for knowledge representation,and presented associa-tion rule’s conceptual relationship knowledge representation algorithm,association rule’s instance compared algorithm,as well as association rule’s knowledge representation optimizing algorithm.Finally,with the help of experimental data obtained from demographic data of a province,we finished the visualizing analysis for association rules information.Experimental results turn out that the knowledge representation algorithm proposed has better display effect and knowledge-sharing.
