As for large-scale ontology modular partition problem,this paper analyzes the similarity between complex networks and ontology structure,converts ontology to the corresponding concept networks according to its semantic and structural characteristics.It proposes a set of quantitative criteria for measuring the local central of nodes and semantic connection strength of edges,uses these quantitative criteria to identify core concept nodes and assign weight to edges,obtains undirected weighted hierarchical networks,which explicit express ontology semantic and structural characteristics,transforms the networks to circuit voltage networks,and partitions it by the maximum potential difference method.Experimental results show that this method can acquire high-quality ontology modules in linear time and fit for the further use of ontology matching application.
