As a result, the similarity measure computation can produce results that are better than those produced using conventional techniques. In one implementation, the similarity measure computation involves combining two similarity results: a first similarity result corresponding to common semantics found in the two concepts and a second similarity result corresponding to dissimilar semantics found in the two concepts.
