Haifei Zhang · Journal of Software · 2014
At present, the mediator/wrapper integration methods are widely used in ontology based data integration because they solve the data update problems of data warehouse method. The key of this method is building of mapping from the global ontology in mediator to the local ontology in wrapper. This article analyzes the general mapping methods and designs a SPARQL query driven Global Local as View (GLAV) mapping method, it is proved in the experiment that this method can effectively support query decomposition and makes the ontology-based integration system has very good extensibility.
