A structural information method for evaluating concept similarity
Lidong Wang, Dianxuan Gong · 2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery · 2010
Assessing concept similarity is an importance activity in ontology engineering. In this paper, a new similarity measure model is proposed, in which the information content of meet-irreducible elements is employed to evaluate the similarity degree of the two concepts of concept lattice. The proposed method combines featural and structural information into decision and preserves more structure information of concept lattice, which can be viewed as the development of Souza and Davis's model. Moreover, we give a method to find meet-irreducible elements of concept lattice by using attributes classes, rather than constructing Hasse Diagram or looking through all concepts of the context.
