The real entities can have features whose representation in an ontology is implicit; and although they may be inferred by a human agent, they cannot be inferred by a machine agent. Moreover, some of these features, called contextual features, have an interpretation that depends on the context in which the entity is considered. These features are not required to be made explicit when the entities are considered within the same context, but it becomes necessary when the entities have to be interpreted in another one. The main contribution of this chapter is a method for enriching the representation of entity semantics in an ontology by making contextual features explicit with the aim of improving the matching between heterogeneous ontologies.
