Abstract

While there has been a great deal of work concerning distributed reasoning with ontologies, in most cases either only TBox reasoning is concerned, or ABox reasoning is supported for languages of limited expressivity. To a greater extent than other representation frameworks, the proposed $E^{DDL} _{HQ^+}$ $\mathcal{SHIQ}$ framework allows peers to establish concept-to-concept semantic correspondences to acquaintances' ontologies via bridge rules, and relate individuals by equivalence correspondences or link assertions for the $\mathcal{SHIQ}$ fragment of Description Logics. The paper presents $E^{DDL} _{HQ^+}$ $\mathcal{SHIQ}$ and proposes an algorithm for the retrieval of individuals in a distributed setting.
