Ontology Mapping Approach Based on Concept Dimensions

Ontologies are significant for the development of the semantic web, which could implement the information reusing and knowledge sharing. With the number of ontologies increasing rapidly, ontology mapping is a useful method to clear up the heterogeneity among ontologies so that ontologies could understand each other properly. Structures information is important for mining semantic relation during ontology mapping. In the ontology hierarchy, vertical information is the main factor used in many mapping methods, while the horizontal relation is not employed fully yet. In this paper, from the aspect of the dimensions of the concept in ontologies, which describes the horizontal relation of ontology concepts, an ontology mapping approach is proposed. The values on concept dimensions could be named concepts, intersections, unions, complements or restrictions. They are compared with ontology concepts to help ontology mapping. Experiments indicate that the concept dimension is an important factor infecting ontology mapping.
