  5. 5. DATA, INFORMATION AND CONTENT Data is raw. It is numbers and patterns that have no interpretation Processed Data is Information Content is digestible form of Information
  6. 6. WHAT IS SEMANTIC WEB ? Group of methods and technologies The Semantic Web = a Web with a meaning searching, aggregating and combining of the Webs information Access Meaningful and accurate information Data are interlinked

  8. 8. IDENTITY
  9. 9. DEFINITIONApple
  10. 10. ADVANTAGES OF MACHINES They process long and complex computing Comparing and indexing large data Searching millions of data
  11. 11. ADVANTAGES OF HUMANS We know the meaning Relations Logical Intelligence
  12. 12. MAKING THE EXISTING DATA MEANINGFUL Rules or Ontologies Semantic Programming Techniques Data and Metadata Together
  13. 13. LINKED DATA
  14. 14. EXAMPLE Facebook Graph Google Knowledge Graph
  15. 15. WHY IT IS IMPORTANT TO BE SEMANTIC ? Everyone is smarter now (Google Search ) The more we know about, the more is the visibility and accuracy Personalisation
