Transcript

  • 1. SAmgI: Automatic Metadata Generation v2.0 Michael Meire, KULeuven, Belgium Xavier Ochoa, ESPOL, Ecuador Erik Duval, KULeuven, Belgium 2007
  • 2. Agenda
    • Why Automatic Metadata Generation?
    • AMG v.1 – What Went Wrong
    • SAmgI – What is New
    • SAmgI in Action
    • SAmgI to the Test
    • Make SAmgI yours!
  • 3. Economy of Abundance
  • 4. Economy of Abundance Put your LMS here!
  • 5. Managing Abundance
    • But those resources have to be:
      • Found
      • Shared among tools
      • Evaluated by users
      • Assembled together
      • Related to each other
      • Branched in new versions
  • 6.

    Managing Abundance This is a job for … METADATA
  • 7. But WHO will create all this metadata?
  • 8. ARIADNE Grow
  • 9. ARIADNE Grow Librarian metadata doesn’t scale!
  • 10. Automatic is the Way…
    • GATE ( Cunningham et al. 2002 )
    • AMeGA (Greenberg et al. 2005)
    • Magic system (Ying et al. 2005)
    • AMG (Cardinaels et al. 2005)
    • Use information about the Object and its Context to extract or generate its metadata
  • 11. AMG v.1 Design
    • Integrate existing extraction algorithms
    • Two groups of Generators/Indexers:
      • Object Based Extractors
      • Context Based Extractors
    • Extraction/Generation Toolbox
      • Keywords, Summarization, Language, EXIF
  • 12. AMG v.1 Design
  • 13. AMG v.1 What Went Wrong
    • It was an application
    • Not as flexible as initially thought
    • Initial set of extraction tools was too basic
    • It was Java only
  • 14.

    AMG v.1 What Went Wrong If at first you don't succeed…
  • 15. SAmgI – What is New
    • Simple AMG Interface
    • Main Design Goals:
      • Easily Extendable
      • Service Oriented
  • 16. Easily Extendable
  • 17. Service Oriented
  • 18. Service Oriented
  • 19. Service Oriented
  • 20. SAmgI in Action
    • Projects deploying SAmgI:
      • MACE ( http://www.mace-project.eu/ )
      • MELT ( http://info.melt-project.eu/ )
      • ACKNOWLEDGE ( http://projects.ibbt.be/acknowledge )
      • GLOBE network ( http://globe-info.org/ )
  • 21. SAmgI in Action
    • Try it online:
      • http://www.cs.kuleuven.ac.be/~hmdb/amg
  • 22. SAmgI to the Test
    • 22 reviewers for 20 LOM records
      • 10 human generated (from Ariadne KPS)
      • 10 SAmgI generated (from Prolearn deliverables)
    • 7 quality parameters (Bruce & Hillman framework)
      • Completeness
      • Accuracy
      • Provenance
      • Conformance to expectations
      • Logical consistency and coherence
      • Timeliness
      • Accessibility
  • 23. SAmgI to the Test
  • 24. SAmgI to the Test No significative difference in Quality!
  • 25. Make SAmgI yours!
    • Option 1: SAmgI as a black box
      • Minimum programming
      • No context information
      • Small set of metadata.
    • Option 2: Create a CBG
      • Reuse all the other services
      • Rich metadata set
      • Some programming required
  • 26. Make SAmgI yours!
    • Source:
      • Sourceforge – ARIADNE KPS Project
