Ontologies are used to represent the semantics of entities of reality in several application domains, leading to different domain ontologies. In order to enable semantic integration of heterogeneous information sources using ontologies, appropriate matching techniques are required. In the last years, different techniques have been proposed. However, these techniques work poorly when there are incomplete representations of entities, which is usually the case in practice. With the aim of improving the representation of entities in an ontology, this paper proposes a method for making features, whose interpretation depends on the considered context, explicit. In addition, an application example is discussed.
