Ontology Mapping Based on GRA
Jianer Chen · Journal of Chinese Computer Systems · 2009
Ontology mapping created by endusers contains class hierarchy structure knowledge of the domain,and using that knowledge could produce new domainal ontology mapping.However,current systems have the following drawbacks: insufficient consideration of class hierarchy complexity,incompletely deleting inconsistent knowledge and inefficiency.Aiming at solving those problems,this paper proposes a new method of dealing differently with similar to and equal to relations in grass-roots ontology alignment.Besides,this paper redesigned inferences on class hierarchy knowledge base.The experiment result shows that revised system is more efficient than the original one,can produce results with higher precision while maintaining high recall,and can support complex ontology mapping.
