  12. 12. Better search More targeted ads Smarter collaboration Deeper integration Richer content Better personalization The semantic graph connects everything… Emails Companies Products Services Web Pages Multimedia Documents Events Projects Activities Interests Places
  13. 13. Beyond the limits of keywords..
  14. 14. ? <ul><li>Lets consider one example.. </li></ul><ul><li>I have a hobby of collecting stamps. </li></ul><ul><li>I have collected so many stamps over years.. </li></ul>

  17. 17. Structuring the web.. <ul><li>Solution to the problem we face while searching is to structurally describe that Stamp is a STAMP and red is a COLOR. </li></ul><ul><li>Describing the data in Databases. </li></ul>
  18. 18. Different databases can be connected. A database with stamps A database with countries A database with colours A database with stamp traders
  19. 19. Components that will make web a semantic web <ul><li>Identifiers: Uniform Resource Identifier [URI] </li></ul><ul><li>Documents: Extensible Markup Language </li></ul><ul><li>Statements: Resource Description Framework </li></ul><ul><li>Provides a formal description of concepts , terms and relationships </li></ul>
  20. 20. Identifiers : Uniform Resource Identifier <ul><li>Used to indentify items on web </li></ul><ul><li>Each item considered as resource </li></ul><ul><li>Each resource has URI </li></ul><ul><li>Just gives identification not location unlike URLs </li></ul><ul><li>Name to a resource </li></ul><ul><li>Decentralized </li></ul>
  21. 21. Documents : Extensible Markup language <ul><li>Simple way to send documents across the web </li></ul><ul><li>Allows anyone to create own document format. </li></ul><ul><li>Machine-readable </li></ul><ul><li>“ emphasize” </li></ul><ul><li>Ex.1.:~ “I just got a new pet dog.” </li></ul><ul><li><sentence> </li></ul><ul><li><person>I</person> just got a new pet< animal>dog</animal>. </li></ul><ul><li></sentence> </li></ul>

  23. 23. Statements : Resource Description Framework [RDF] <ul><li>RDF is a markup language to describe information and resource available on web. </li></ul><ul><li>Putting in RDF makes it possible to get it on web. </li></ul><ul><li>Simple model based </li></ul><ul><li>Designed to be read and understood by computers </li></ul><ul><li>RDF statement is lot like simple sentence , except almost all words are URI. .Subject .Predicate .Object </li></ul><ul><li>Ex.2. :~ “Aaron really likes Berner-Lee's weaving the web” </li></ul><ul><li><> </li></ul><ul><li><> </li></ul><ul><li>< the web> </li></ul>
  24. 24. RDF queries… <ul><li>Why use RDF rather than XML? </li></ul><ul><ul><li>Directly and unambiguously into Model </li></ul></ul><ul><ul><li>Decentralized </li></ul></ul><ul><ul><li>Generic parsers available </li></ul></ul><ul><ul><li>Part of semantic web </li></ul></ul><ul><li>Do we use XML schema in conjunction with RDF? </li></ul><ul><ul><li>Language that restricts XML syntax </li></ul></ul><ul><ul><li>RDF has its own Normalization Forms </li></ul></ul><ul><ul><li>No [partially] </li></ul></ul><ul><ul><li>possibly </li></ul></ul>

  26. 26. Web 3.0 : cloud <ul><li>Software as a Service </li></ul><ul><li>Data as a Service </li></ul><ul><li>Resource as a Service </li></ul><ul><li>Every developer around the world can access the same powerful cloud infrastructures </li></ul><ul><li>Because code lives in the cloud, global talent pools can contribute to it </li></ul><ul><li>Because it runs in the cloud, a truly global market can subscribe to it as a service </li></ul>
  27. 27. Web 3.0 : Artificial Intelligence <ul><li>An extension of the Semantic web concept </li></ul><ul><li>Academic research is being conducted to develop software for reasoning, based on description logic and intelligent agents, for example, the ''World Wide Mind'' project </li></ul><ul><li>Companies such as IBM and Google are implementing new technologies that are yielding surprising information </li></ul>
