Semantic Matching of Ontologies

Year 2010
PDF URL view

The discovery of semantic relationships such as subsumption and disjointness is still a challenge in ontology matching. Existing methods use logical reasoning over computed equivalence relationships or machine learning based on lexical and structural features of ontology elements. While these methods deliver good results for some cases, they are limited to the information contained in the input ontologies to be matched. Therefore, background knowledge in form of an additional ontology may be useful to detect semantic relationships. In existing approaches, the identification of an appropriate ontology as background knowledge is often a task left for the user. We present two enhanced approaches for identifying semantic relationships. The first one is based on background knowledge; in contrast to other approaches, it is able to identify a background ontology automatically. The second approach builds on existing machine learning methods for identifying semantic relationships. We present first evaluation results for these two methods and also present combined approaches which show that the integration of these methods is reasonable as more semantic relationships are identified.
