Augmentation of ontology instance matching by automatic weight generation

The proliferation of heterogeneous sources of ontology instances of semantic knowledge base raises a research issue of automatic matching of instances. However, automatic instance matching is heavily affected by the weight of property associated to instances. Measuring the property weight automatically is a formidable task. In this paper, we propose an efficient method of measuring weight automatically and apply the method for augmentation of our state-of-the-art instance matcher, which consider the semantic specification of properties associated to instances, for matching with heterogeneous instances of semantic knowledge base. Our experiments and evaluations shows the effectiveness of automatic weight generation in ontology instance matching over various transformations of a dataset: value transformation, logical and structural transformation.
