To solve the problem of ontology instance redundancy in heterogeneous electronic catalog integration,this paper proposes a mechanism of instance duplicate elimination for electronic catalog ontology merging.This mechanism incorporates ontology concepts,attributes relationships into the calculation of semantic similarity between two ontology instances,while semantic similarity on concepts is calculated by string matching and Wordnet,that on attributes is calculated according to both data-type and object-type,and that on relationships is calculated based on multi-inheritance.If two instances have a semantic similarity above the preset threshold,one of them is deleted from ontology base to ensure the efficiency of operation on ontology instances.Experimental results show the validity of this mechanism.
