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

Monday, September 21, 2009

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?

• Linked Data & SKOS for background info

• RDFa/FOAF++ to publish simple profiles

• Topics indicated by URI (SKOS or id)

• Weighted Topics (VoCamp work)

• Use and extend OpenSocial APIs
