Concept similarity in Formal Concept Analysis: an Information Content Approach

ABSTRACT
{it Formal Concept Analysis} (FCA) is revealing interesting in supporting difficult activities that are becoming fundamental in the development of the Semantic Web. Assessing {it concept similarity} is one of such activities since it allows the identification of different concepts that are semantically close. In this paper, a method for measuring the similarity of FCA concepts is presented, which is a refinement of a previous proposal of the author. The refinement consists in evaluating the similarity of concept descriptors (attributes) by using the {it information content} approach, rather than relying on human domain expertise. The information content approach which has been adopted allows a higher correlation with human judgement than other proposals for evaluating concept similarity in taxonomy defined in the literature.
