Overview#Semantic WEB is an extension of the World Wide Web through standards by the World Wide Web Consortium (W3C)
Semantic WEB standards promote common data formats and exchange protocols on the Web. "The Semantic WEB provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries". The Semantic WEB is therefore regarded as an integrator across different content, information applications and systems.
Semantic WEB involves publishing in languages specifically designed for data:
- Resource Description Framework (RDF)
- Web Ontology Language (OWL)
- Extensible Markup Language (XML)
- Web Linking (Atom)
These technologies are combined in order to provide descriptions that supplement or replace the content of Web documents. Thus, content may manifest itself as descriptive data stored in Web-accessible databases, or as markup within documents. The machine-readable descriptions enable content managers to add meaning to the content, i.e., to describe the structure of the knowledge we have about that content. In this way, a machine can process knowledge itself, instead of text, using processes similar to human deductive reasoning and inference, thereby obtaining more meaningful results and helping computers to perform automated information gathering and research.
