A Query Driven Method of Mapping from Global Ontology to Local Ontology in Ontology-based Data Integration

摘要

At present, the mediator/wrapper integrationmethods are widely used in ontology based data integrationbecause they solve the data update problems of datawarehouse method. The key of this method is building ofmapping from the global ontology in mediator to the localontology in wrapper. This article analyzes the generalmapping methods and designs a SPARQL query drivenGlobal Local as View (GLAV) mapping method, it is provedin the experiment that this method can effectively supportquery decomposition and makes the ontology-basedintegration system has very good extensibility.
