ONLINE FORUM REVISITED 10. THE SEMANTIC WEB 11.

  • The Semantic Web is anextension of the current webin which information is givenwell-defined meaning , better enabling computers and people to work in cooperation.
    • Berners-Lee, Hendler and Lassila, Scientific America, May,2001 10
  • The Semantic Web is a vision: the idea of having data on the web defined and linked in a way that it can be used by machines not just for display purposes, but for automation,integration and reuseof data across various applications.

  • Semantics isthe study of meaningwhich can be express in a language, code, or other form of representation.

WE SEE 17. THE MACHINE SEES 18. THE SOLUTION : MARKUP? 19. THE MACHINE (STILL) SEE 20. Syntactic vs Semantics web Evolution of the web (Cardoso & Sheth, 2006) Evolution of the web (Cardoso & Sheth, 2006) Evolution of the web (Cardoso & Sheth, 2006) Evolution of the web (Cardoso & Sheth, 2006 ) 21. Levels of semantics HOW IT WORKS ONTOLOGY 22. example 23.

  • to make domainassumptions explicit

Paul Downey HOW IT WORKS ONTOLOGY (WHY) 24. RDF is a Data Model HOW IT WORKS RDF 25. HOW IT WORKS RDF 26. HOW IT WORKS RDF 27. + Semantic e-learning is the e-learning based on the Semantic Web technologies that can easily provide learning materials in a common format and therefore enhance personalised learning( Cao & Zhang, 2006) 28.

  • Structure : As Laurillard (2002) indicates, one central component of learning is coming to see structure. Structure means of seeing something (a theory, or concept) as a whole which includes the relations which link these to other ideas and theories and stated interdependencies

WHATS THE SIGNIFICANCE Set of concept Connecting concept with material 29. example 30. Lemnitzer, L., Mossel, E., Simov, K., Osenova, P., & Monachesi, P. (2008).
