Developing ontologies is not an easy task and often the resultingontologies are not consistent or complete. Such ontologies,although often useful, also lead to problems when used insemantically-enabled applications. Wrong conclusions may bederived or valid conclusions may be missed. To deal with thisproblem we may want to repair the ontologies. Up to date most workhas been performed on finding and repairing the semantic defectssuch as unsatisfiable concepts and inconsistent ontologies. Inthis paper we tackle the problem of repairing modeling defects andin particular, the repairing of structural relations (is-ahierarchy) in the ontologies. We study the case where missing is-arelations are given. We define the notion of a structural repairand develop algorithms to compute repairing actions that wouldallow deriving the missing is-a relations in the repairedontology. Further, we define preferences between repairs. We alsolook at how we can use external knowledge to recommend repairingactions to a domain expert. Further, we discuss an implementedprototype and its use as well as an experiment using theontologies of the Anatomy track of the Ontology AlignmentEvaluation Initiative.
