A Resource Classification System for the WOS

There are many standardized communication protocols that define the interaction between entities, but often they fall short in providing clues about the meaning of the data exchanged and the service provided. In order to enhance interaction between WOS nodes, an agreement on the meaning of data and services is required. The impossibility to classify resources on theWeb in a reasonable amount of time asks for support of multiple classifications that can evolve locally and independently. This paper introduces classifiers that together with local ontologies add semantics to resources. It looks at the problem of merging multiple ontologies as it might be necessary in communities of WOS nodes. The design of a WOS warehouse based upon classifiers and ontologies is presented.
