摘要：In recent years the data integration based on ontology is an effective method to solve the heterogeneous data on the Internet. An extend hybrid ontology approach has been proposed by analyzing the single ontology, multi-ontology and hybrid ontology. This method uses ontology web language ontology to represent the global ontology, local ontology and the mapping rules among them. The mapping rules can be modified according to the dynamic change of data source. The advantage of this method is that new data source can be easily added and when the single data source is changed, but the global ontology will not be modified.
