Abstract
Many representative applications on the semantic web, including collaborative ontology building, partial ontology reuse, selective knowledge hiding and distributed data management, call for modular ontologies,. However, although OWL allows using owl:imports to connect multiple ontologies, its current semantics requires all involved ontologies to have a single global semantics, thus providing only a syntactical solution to modularity. As a result, there is a growing interest in modular ontology languages such as Distributed Description Logics (DDL) [7] and \({\mathcal{E}}\)-connections [8]. However, these proposals are also limited in expressivity and reasoning soundness [2,3].KeywordsDescription LogicOntology ServerRepresentative ApplicationOntology ModuleKnowledge HidingThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
