Abstract

As the WWW makes a vast amount of information assets of various types accessible to the Internet user, it becomes increasingly important to retrieve assets that a) are semantically related and b) cover a broad range of asset types. Most current Web search engines like Yahoo or Excite that provide only keyword{search capabilities fall short of either requirement. Attribute{ and content{search make use of meta-data, modeled in domain{speci c and domain{independent ontologies. They can substantially enhance the result to a given information request. In this thesis, we formalize and detail the Metadata Reference Link (MREF), a means to correlate information across ontologies, asset types, and resources on a resource{independent level, integrating all three search techniques for best results. The multi{agent system that processes the MREF and a detailed scenario involving multiple ontologies and real world data are also discussed.
