A distributed description logic approach to semantic annotation

Semantic annotation plays a central role in building the semantic Web, which in general could be completed by committing a Web resource to a domain ontology. However, there exist many circumstances in which semantic annotation needs more than one ontologies. We propose an approach based on distributed description logics (DDL) with intention to deal with these circumstances, in which ontologies form a distributed system, and no extra conditions and changes are imposed to those component ontologies.
