Comparing ontological concepts to evaluate similarity

Anton Andrejko, Michal Barla, and Michal Tvarožek

Various stages of data processing need to compare the concepts they work with. In case of the object-oriented paradigm we often use methods, which allow us to compare objects to other objects. In this paper, we present a method for the comparison of ontological concepts and the evaluation of their similarity. We identified two types of comparisons. First, the evaluation of distance between concepts by exploiting the taxonomy of classes in the used ontology. Second, the comparison of concepts' attributes, where we consider object type attributes and data type attributes. We describe the Concept Comparer software tool (ConCom), which compares concepts from an existing job offer domain ontology and quantitatively expresses their similarity.
