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

    • Faceted Navigation of User-Generated Metadata JDCL 2006 Workshop on Metadata Tools for Digital Resource Repositories Bradley P. Allen Founder & CTO Siderean Software, Inc.
    • Overview
      • Faceted navigation depends on metadata
      • Users are increasingly a source of rich, dynamic metadata
      • User-generated metadata provides opportunities for new and compelling applications of faceted navigation
    • 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
    • Faceted navigation requires metadata
      • Faceted navigation depends on metadata
      • This metadata has traditionally come from
        • Relational databases
        • Content repositories
        • Labor-intensive manual processes
    • Users can be a source of metadata
      • Faceted navigation creates a framework to bridge the gap between metadata and the user
        • Exploit implicit (usage) and explicit (subject) user-generated metadata to reduce labor costs of the repository
        • Leverage the metadata which is at hand in increasing amounts on the Web
          • RSS, FOAF, SKOS, etc.
    • Example: user tagging
      • User tagging is massively collaborative subject indexing with uncontrolled vocabularies
        • A new point on the metadata cost/value continuum pioneered by del.icio.us, Flickr
      • How can this play with traditional subject indexing?
        • Folksonomies can make taxonomies more responsive
        • Taxonomies can make folksonomies more responsible
    • Case study: fac.etio.us
    • Case study: fac.etio.us

    • User-generated metadata: the value chain
      • Publishers
        • User-generated metadata increases the value of core content and data offerings
      • Contributors (enthusiasts, editors, remixers, librarians)
        • Tools for remixing, tagging, annotating and playlisting content and data enhance value at the metadata level
      • Consumers
        • More navigable rich data and content
      • Advertisers
        • Higher-yield ads based on paid navigation rather than paid search

    • Questions
      • Where else can we end up on the user metadata creation cost/value continuum?
      • Can we get more value by filling out a few more fields?
        • Possible approach: case frame instantiation in Poptonic
