E-Learning on Social Semantic Information Sources Presentation Transcript

  • 1. E-Learning on the Social Semantic Information Sources Sebastian Ryszard Kruk, Adam Gzella , Jarosław Dobrzański, Bill McDaniel and Tomasz Woroniecki adam.gzella @deri.org
  • 2. Outline
    • Problems and possible solutions
    • Introduction to SIOC, SSCF and JeromeDL
    • Our solution
    • Conclusions
  • 3. „ John’s problems” – motivation scenario
    • John - teacher in a distant course
    • Each lecture assisted with reading material
      • Should be distributed week before lecture
    • John wants to check if students read and understand
    • Gathered knowledge passed to the next year’s course.
    • He wants to utilise the power of Web/Web2.0 - most materials from:
      • University library
      • Wikipedia
      • Online sources (like blogs)
  • 4. John’s solution
    • Decide to use:
      • Web/Web2.0 potential
      • Bookmarks sharing tool
      • Blog platform
  • 5. Is there a better way?
    • Solution needs to be interoperable and universal
    Social Semantic Information Sources
  • 6. SIOC – connecting online communities
    • Simple but powerful
    • SIOC ontology – describes community metadata
    • Can be used for blogs, wikis and foras
    • Allows to:
      • Cross-site queries
      • Topic related searches
      • Importing data from other sites
      • ... and many other
  • 7. Sharing knowledge in community with SSCF
    • SSCF – Social Semantic Collaborative Filtering
    • Gathering knowledge as a bookmarks
    • Bookmarks can be easily shared with friends
    • Users use friends bookmarks (possible domain expert)
    • Directories are well (semanticaly) described with wordNet and taxonomies
    • Fine grained access rights.
  • 8. Sharing knowledge in community with SSCF
  • 9. SSCF and SIOC
    • SSCF supports SIOC data
    • User can bookmarks blogs post or even whole blogs
    • SIOC bookmarks are treated as standard SSCF resource.
  • 10. JeromeDL – Semantic Digital Library
    • Semantic Digital Library
      • Digital Library with reach semantic annotations.
      • Advanced semantic search features.
  • 11. JeromeDL – Social Semantic Digital Library
    • Social Semantic Digital Library
    • community oriented:
      • Enriched with SSCF.
        • Each user maintains private bookshelf with bookmarks to bibliographic resources
      • Allows to the community to create knowledge (SIOC integration)
        • Each book becomes a blog entry which can be commented
        • Data is exposed in SIOC format.
  • 12. Our solution
    • One tool that solves all the John’s problems
  • 13. How it works for John
    • Bookmarking interesting content and sharing it with students in right order.
    • Students sharing with each other
    • Students build new knowledge in JeromeDL
    • All the experience is available for next year students
  • 14. What is happening JeromeDL creating knowledge SSCF sharing knowledge SIOC Exposing book comments In SIOC Support for SIOC enabled information
  • 15. Ontology mapping
    • SIOC with JeromeDL and SSCF:
      • Support for SIOC ontology – RDF level.
      • Ontology alignment
  • 16. Time evaluation
    • JeromeDL is much more efficient than 3 separate applications (digital library, blog engine, bookmarks sharing engine)
  • 17. notitio.us
    • SSCF is now part of notitio.us – semantic discovery, browsing and sharing
      • Universal bookmarking system
    • Notitio.us is equipped with Informal Knowledge Harvester
      • Transforms informal knowledge into LOM and other formats.
  • 18. Conclusions
    • Social Semantic Information Sources – JeromeDL and SSCF:
      • Utilise Web 2.0 and Semantic Web potential
      • Can be very helpful in modern, web oriented e-Learning.
