Abstract

In this paper we describe a framework for the application of semantic granularities to the Semantic Web Given a data source and an ontology formalizing qualities which describe the source, we define a dynamic granularity system for the navigation of the repository according to different levels of detail, i.e., granularities Semantic granularities summarize the degree of informativeness of the qualities, taking into account both the individuals populating the repository, which concur in the definition of the implicit semantics, and the ontology schema, which gives the formal semantics The method adapts and extends to ontologies existing natural language processing techniques for topics generalization.
