SAmgI: Automatic Metadata Generation v.2
Download as PPT, PDF3 likes888 views
The document discusses the automatic metadata generation system known as SAMGI, its shortcomings in version 1.0, and the improvements made in version 2.0. It highlights the necessity of metadata in managing abundant resources and presents projects utilizing SAMGI, along with its testing results showing no significant quality differences between human-generated and SAMGI-generated metadata. Additionally, it offers options for using SAMGI in different contexts.

- 6. But those resources have to be: Found Shared among tools Evaluated by users Assembled together Related to each other Branched in new versions … 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. It was an application Not as flexible as initially thought Initial set of extraction tools was too basic It was Java only 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

- 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
