Faceted Navigation of User-Generated Metadata (JDCL 2006 Workshop on Metadata Tools for Digital Resource Repositories)

  1. 1. Faceted Navigation of User-Generated Metadata JDCL 2006 Workshop on Metadata Tools for Digital Resource Repositories Bradley P. Allen Founder & CTO Siderean Software, Inc.
  2. 2. Overview <ul><li>Faceted navigation depends on metadata </li></ul><ul><li>Users are increasingly a source of rich, dynamic metadata </li></ul><ul><li>User-generated metadata provides opportunities for new and compelling applications of faceted navigation </li></ul>
  3. 3. Building a faceted navigation application (in Seamark) Analyzed to generate an application profile for faceted navigation of the aggregated metadata Presented as an end-user navigation application Metadata about data and content is aggregated Transformed into a unified information architecture expressed in RDF/OWL Term Event Person Place Text
  4. 4. Faceted navigation requires metadata <ul><li>Faceted navigation depends on metadata </li></ul><ul><li>This metadata has traditionally come from </li></ul><ul><ul><li>Relational databases </li></ul></ul><ul><ul><li>Content repositories </li></ul></ul><ul><ul><li>Labor-intensive manual processes </li></ul></ul>
  5. 5. Users can be a source of metadata <ul><li>Faceted navigation creates a framework to bridge the gap between metadata and the user </li></ul><ul><ul><li>Exploit implicit (usage) and explicit (subject) user-generated metadata to reduce labor costs of the repository </li></ul></ul><ul><ul><li>Leverage the metadata which is at hand in increasing amounts on the Web </li></ul></ul><ul><ul><ul><li>RSS, FOAF, SKOS, etc. </li></ul></ul></ul>
  6. 6. Example: user tagging <ul><li>User tagging is massively collaborative subject indexing with uncontrolled vocabularies </li></ul><ul><ul><li>A new point on the metadata cost/value continuum pioneered by del.icio.us, Flickr </li></ul></ul><ul><li>How can this play with traditional subject indexing? </li></ul><ul><ul><li>Folksonomies can make taxonomies more responsive </li></ul></ul><ul><ul><li>Taxonomies can make folksonomies more responsible </li></ul></ul>
  7. 7. Case study: fac.etio.us
  8. 8. Case study: fac.etio.us
  9. 9. Faceted navigation + tagging
  10. 10. Faceted navigation + tagging
  11. 11. Case study: fac.etio.us
  12. 12. Case study: fac.etio.us
  13. 13. Case study: fac.etio.us
  14. 14. User-generated metadata: the value chain <ul><li>Publishers </li></ul><ul><ul><li>User-generated metadata increases the value of core content and data offerings </li></ul></ul><ul><li>Contributors (enthusiasts, editors, remixers, librarians) </li></ul><ul><ul><li>Tools for remixing, tagging, annotating and playlisting content and data enhance value at the metadata level </li></ul></ul><ul><li>Consumers </li></ul><ul><ul><li>More navigable rich data and content </li></ul></ul><ul><li>Advertisers </li></ul><ul><ul><li>Higher-yield ads based on paid navigation rather than paid search </li></ul></ul>Publishers Contributors Advertisers Consumers Tags, attention Ads and links Tags and leads Tags, facets and remixes Digital assets Tags and facets Tags, attention Digital assets
  15. 15. Questions <ul><li>Where else can we end up on the user metadata creation cost/value continuum? </li></ul><ul><li>Can we get more value by filling out a few more fields? </li></ul><ul><ul><li>Possible approach: case frame instantiation in Poptonic </li></ul></ul>
