Future of vocabularies

  1. 1. Future of vocabularies SCIS and linked data Ben Chadwick, Metadata analyst 14 November 2013
  2. 2. Where are we now? 2012 • Why vocabularies? • How to manage multiple vocabularies? 2013 • Linked data • Curriculum vocabularies Reynolds, Leo 2006, niche, CC-by-nc-sa
  3. 3. Controlled vocabularies "High levels of precision and recall, the two ways in which we judge any information retrieval system, are dependent on controlled vocabularies and national and international standards they cannot be obtained by other systems not involving human intervention.” Michael Gorman foreword to Conversations with Catalogers in the 21st Century, Libraries Unlimited, 2011 (p. viii)
  4. 4. How do vocabularies help search? • • • • • • Search expansion and faceting Navigation and browsing Collections Redirects (“See”) Related topics (“See also”) Mapping between repositories
  5. 5. Australian Education Vocabularies
  6. 6. ScOT thesaurus
  7. 7. About ScOT o About school curriculum and the teaching profession o 9232 concepts o 10 top concepts o 9441 broader/narrower relations o 7775 alternate labels/ synonyms o Used since 2003 for tagging education resources o Used since 2011 to tag the Australian Curriculum
  8. 8. API – SPARQL and RESTful

  10. 10. ScOT as Linked Open Data • Unique Identifiers for concepts • Linked to other unique identifiers (inside and outside the vocabulary) • Open: – Available for consumption on the open web – Expressed in a standard, machine-readable format (RDF)
  11. 11. e-Portfolio
  12. 12. Australian Curriculum
  13. 13. Architecture of the curriculum Learning Areas English Mathematics Science History Geography Arts F-10 Health & Phys Ed F-10 Civics and Citizenship 3-10 Economics & Business 5-10 Languages F-10 Technologies F-10 Work Studies 9-10 Cross-curriculum priorities Aboriginal and Torres Strait Islander histories and cultures Asia and Australia’s engagement with Asia Sustainability

  19. 19. Tagging resources 20,000 resources tagged in Scootle 350,000 resources tagged in SCIS MARC records
  20. 20. Inference o Common vocabulary o Leverage past tagging o Exploit hierarchy
  21. 21. ScOT in Australian Curriculum Curriculum Link content with high correlation of SCOT tags
  22. 22. Exploiting the hierarchy Curriculum Link content with high correlation of SCOT tags
  23. 23. ScOT’s Curriculum Connect tool
  24. 24. Directions for SCIS • • • • • • • • Curriculum alignment: to MARC or not to MARC? Old records without ScOT terms Non-subject vocabularies: Audience? Learning area? Increased records for digital learning resources Retrospective updates of schools’ SCIS records Viability of Linked Open Data (LOD) authorities? A new model for Authority File subscriptions? Viability of LOD records. What would this mean?
  25. 25. Curriculum vocabularies in MARC 658 Curriculum Objective Element Number of records with this field in WorldCat: • 4,679 total as of 1 Jul 2013 • overall number of holdings: 63,847
  26. 26. SCIS Subject Headings test project
  27. 27. Concept display
  28. 28. LOD for Bib Records – final thoughts What would it mean for SCIS? For systems? • Capacity to pull data. Automatic updating • Local copies versus dynamic querying Exposing local holdings to the web, with semantic markup • LRMI ( • BIBFRAME (Library of Congress)
