| Abstract: | Network thesaurus is based on distributed term relation units. Resource object should be indexed and retrieval with the assistance of RDF/XML thesaurus. The difference between XML DTD and RDF schema lies in syntax and symanic,the latter is more extensible and simple with namespace and URI facilities. The thesaurus should be presented on two level: term level and higher concept level. Two kinds of relation:Related Concept and Broader Concept are defined to describe relation between concepts. In the Client/Server environment,the query message can also be format in RDE. RDF and DC vocabularies can combine to describe Web resource. |
