Exploiting the structure of background knowledge used in ontology matching

We investigate the use of a background knowledge ontology in ontology matching. We conducted experiments on matching two medical ontologies using a third extensive one as background knowledge, and compare the results with directly matching the two ontologies. Our results indicate that using background knowledge, in particular the exploitation of its structure, has enormous benefits on the matching. The structure of the background ontology needs closer examination to determine how to use it in order to obtain maximal benefit.
