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

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

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
