4 WHAT IS SEMANTIC WEB? The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites. It has been described in rather different ways: as a utopic vision, as a web of data, or merely as a natural paradigm shift in our daily use of the Web. Most of all, the Semantic Web has inspired and engaged many people to create innovative semantic technologies and applications. 4 Source – http://semanticweb.org/wiki/Main_Pagehttp://semanticweb.org/wiki/Main_Page

11 SEMANTIC WEB TECHNOLOGIES OWL (Web Ontology Language) – Use to Represent Knowledge in Semantic Web Applications Eg – Egg is a Concept. Egg has 6g of Protein. RDF/RDFS (Resource Description Framework) – Data Modelling Language for Semantic Web. All data are stored as RDF triples Eg – SPARQL (SPARQL Protocol and RDF Query Language) – Used to Query RDF Datasets 11 Source – http://www.semanticfocus.com/blog/entry/title/introduction-to-the-semantic-web-vision-and-technologies-part-1-overview/http://www.semanticfocus.com/blog/entry/title/introduction-to-the-semantic-web-vision-and-technologies-part-1-overview/
