Toward semantic similarity measure between concepts in an ontology

Abstract

A concept similarity measure is one classical problem in Description Logic which aims at identifying similarity between concepts in an ontology. Measuring a distance between concepts is an essential process. Most methods used for measuring, they usually do not take semantic for consideration. This work introduces a new method for concept similarity measure. The proposed method semantically analyzes structures of two concepts and then computes the similarity score based on the number of shared structures. The efficiency of the proposed algorithm is measured by means of the satisfaction of desirable properties and intensive experiments on the SNOMED CT ontology.
