Semantic Web: A Primer

  1. 1. Semantic Web, Web 2.0 & Where from here ? Presentation by Narain, Founder & CEO 360 Degree Interactive Gnunify '07, Pune, 28 th Jan. 2007,
  2. 2. What is Semantic Web ? The Semantic Web is an evolution of the World Wide Web in which information is machine processable (rather than being only human oriented), thus permitting browsers or other software agents to find, share and combine information for us more easily.
  3. 3. What makes Semantic Web ? <ul><li>RDF / XML – Resource Description Framework </li></ul><ul><li>RDF is an XML-based standard for describing resources that exist on the web. RDF statements are often referred to as “triples” that consist of a subject, predicate, and object, which correspond to a resource (subject) a property (predicate), and a property value (object). </li></ul><ul><li>Ex. <http://xyz.org/#Narain> <http://xyz.org/#name> &quot;Narain&quot; </li></ul><ul><li>OWL – Web Ontology Language </li></ul><ul><li>OWL defines the types of relationships that can be expressed in RDF using an XML vocabulary to indicate the hierarchies and relationships between different resources. </li></ul><ul><li>SPARQL SPARQL Protocol and RDF Query Language </li></ul><ul><li>SPARQL is a RDF Query Language. RDF query language is a computer language able to retrieve and manipulate data stored in Resource Description Framework format. </li></ul>
  4. 4. Semantic Web stack Presentation by Narain, Founder & CEO 360 Degree Interactive 28 th Jan. 2007,
  5. 5. Web 2.0 & Semantics <ul><li>Harnessing Collective Intelligence - Digg, del.icio.us </li></ul><ul><li>Network Effect - Flickr, YouTube, Mybloglog, </li></ul><ul><li>Sharabilty / Remixability – Mashups [APIs] </li></ul><ul><li>Meta Profile sharing – PeopleAggregator </li></ul><ul><li>Syndication – content, communication, commerce </li></ul><ul><li>Open standards, Open data – Open ID, RSS, Atom </li></ul>

  10. 10. SemWeb – Open ID OpenID is an open, decentralized, free framework for user-centric digital identity . OpenID starts with the concept that anyone can identify themselves on the Internet the same way websites do-with a URI/URL. Since URIs are at the very core of Web architecture, they provide a solid foundation for user-centric identity. Ex. http://narain.myopenid.com Open ID Acceptance: Technorati, userstyles.org, Wikitravel, Zoomr, MoveableType, LiveJournal, Runlog, Imageshack, Wikidentiy, Hampr and more!
