From the web of documents to the linked data

Abstract

We start off this paper with a description of the evolution that led from the first version of the Web to the Web of data, sometimes referred to as the Semantic Web. Based on the “data > information > knowledge” hierarchy, we adopt a usage-based perspective.We then make explicit the structures of knowledge representation and the building blocks of the Web of data. In the next chapters, we show how RDF (Resource Description Framework) data are managed and queried. This allows us to describe an innovative data processing platform which produces linked data. We continue on ontologies, from their creation to their alignment that allows us developing the delicate question of reasoning. We can then conclude on research and development prospects offered by the linked data environment.
