摘要：Ontology mapping is the key challenge in the construction of semantic web, and a hinder in the handling of conflicts among heterogeneous data. We propose an efficient ontology mapping method which adopts a dichotomy approach. In this method, we divide original ontology into several small ones, and establish mapping between them, and at the end combine the local mapping results to get the final result. Compared with the method which doesnt use dichotomy approach, at the best case it will be reduced from n*n to n*logn. Experiments show that the accuracy of ontology mapping is also improved when the ontology has a graphical structure.
