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


Metadata about data and content

is aggregated

Building a faceted navigation application (in Seamark)

Transformed into a unified information architecture expressed in RDF/OWL

Analyzed to generate an

application profile for faceted

Presented as an end-user navigation application


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
