A Method to Compare Concepts between Ontologies

When we do ontology merging or aligning, it is important to compare concepts which are likely to be merging or aligning points in different ontologies. In most cases, concepts with similar names are considered to be promising candidates. However, it is quite probable that concepts with lexically similar names are not semantically similar or compatible. In this paper, we presented a method to compare concepts between two ontologies from four perspectives based on the semantic distance which to capture the meaning of a concept from its position in the containing ontology as well as its defined attributes.
