User Model principles
• Minimalist - Web 2 is beyond our control
• Layered -
• overlay activity stream “layers” from
different sources - eg. last.fm, Amazon
history, youtube logs...
• link to entities - programmes, directors,
places, actors, topics, ...
• levels of detail: activity streams, weighted

Simple Example
• ‘Movies I like include <a rel=”foaf:interest”
href=”http://en.wikipedia.org/wiki/
The_Fog_of_War”>The Fog of War</a>’
• Simple claims that can be made explicitly, data
mined, or through partial-automation

Layers of detail
• simplistic claims (flat lists of interests)
• weighted view: interest (e.g.: movie url, ‘8’)
• activity stream view: person/content/verb/...
• person fields (geo, age, gender, ...) if available

External standards
• Refine OpenSocial API to use URI links:
• eg. OpenSocial.Person.Field.MOVIES
• Person.Field.MOVIES_URIs
• Person.Field.MOVIES_URIs_weighted

In Other Words...
• http://en.wikipedia.org/wiki/Blade_Runner
• http://www.imdb.com/title/tt0083658/
• http://bladerunnerthemovie.warnerbros.com/
• Instead of “Favourite Movie: Blade Runner”

Just identifiers?
• What kinds of thing?
• people, places, series, shows, subject
areas, ... anything we can describe
• But we don’t like all things equally, how to
express weighted relations to a topic?
