The Method of Multi-strategy Ontology Mapping

Ontology is a philosophical concept originally,which describes the natures of objects. Because there is not a common criterion for building ontology, a lot of heterogeneous ontologies are constructed in the same domain.Ontology mapping is an effective method to realize the interoperation of heterogeneous ontology. The key of ontology mapping is to calculate similarities between concepts. In this paper, we propose a multi-strategy ontology mapping method. The concept similarity is computed from the aspects of concept name, concept attribute and concept relationship. What´s more, the candidate set and information gain are brought to improve the accuracy of similarity and to simplify the calculation process. Extensive simulations show that the approach is an effective algorithm and better than others.
