  • 1. NoTube project overview
  • 2. This talk • Project slogans • Architecture • Demonstrators: one example
  • 3. Project slogans
  • 4. “Putting the user back in the driver’s seat” • Personalized services are now common • But: user data is still under control of separate applications • Result: user is faced with multitude of distributed personal data, hidden in tons of inaccessible cookies
  • 5. “TV is not bound to the device” • Multiple device scenarios – use of computer as TV & vice versa – use of mobile device as remote control  Architecture should support device independence
  • 6. “Integration of TV & Web with help of semantics” • Integration of Web & TV is becoming a fact • Many practical software and hardware hurdles for users to handle this integration • Using semantics (linked open data) to open and interlink TV content in a Web fashion
  • 7. Open standards • Focus on standards used by public broadcasters • Combined use of Web & TV standards • Where required: partial alignment of Web and TV standards
  • 8. Out of scope • Content access issues – e.g geo‐restrictions on BBC content • TV content‐analysis research – video analysis – audio analysis • EPG metadata access issues • Privacy legislation
  • 9. First demonstrator
  • 10. Architecture
  • 11. Building blocks: TV metadata services • EPG metadata grabbers – from 170+ channels • Issues – Web representation: e.g. channel URLs – metadata format  TV Anytime – real‐time service
  • 12. Aside: Open Graph Protocol & RDFa
  • 13. Building blocks: metadata enrichment • Making semantics in metadata explicit – e.g. channel name  channel URI • Add links to external Web vocabularies and repositories
  • 14. Building blocks: user activity streams • Standard for activity stream representation – based on Open Social • Access services to activity streams – YouTube, Twitter, …. • Challenge – trusted access to “friend” information – implementation of OAuth 2.0 standard
  • 15. Atom Activity Stream Model sample “verbs”
  • 16. Building blocks: user profiling • Services for generating user preferences – “Beancounter” – abstractions from activity stream • User‐model representation based on FOAF
  • 17. BEANCOUNTER aggregating user information
  • 18. Building blocks: Recommenders • Collaborative recommenders – preferences of friends • Content‐based recommenders – program about Alma Mahler => program about Walter Gropius • Experiment with mix of these recommenders
  • 19. Content recommendations: the role of patterns
  • 20. Pattern occurrences in BBC dataset
  • 21. Pattern examples
  • 22. Hybrid recommendations
  • 23.

  • 24. Sample demonstrator
  • 25. N-Screen demonstrator
  • 26. Suggestions for you
  • 27. Drag-and-drop real-time sharing
  • 28. More information about a programme
  • 29. Changing the TV using drag and drop
  • 30. Social TV survey
  • 31. Some observations about Social TV • People want to watch TV together. They like talking about TV • People like others having watched the same thing as them, and older people miss the days when people were much more likely to have watched something they had. • To get the social benefit they don't have to watch it at the same time as others but sometimes this is fun.
