Jo Kent | ADA – Opening up the BBC archive with linked data

  1. 1. Introducing ADA: Automated Data Architecture Radio & Music Interactive Jo Kent
  2. 2. Some background • The British Broadcasting Corporation (BBC) is the UK's public- service broadcaster. • It is the world's oldest national broadcasting organisation and the largest broadcaster in the world. • It produces news articles, television and radio programmes 24 hours a day. • Somehow that content needs to be findable.
  3. 3. The BBC in 1997 Hand curated links and index pages
  4. 4. Sport Subsections Sections Sport ontology
  5. 5. News Subsections Sections 3 most recent related stories
  6. 6. News App
  7. 7. Music Dynamically populated sections Wikipedia content
  8. 8. Access to our ontologies and objects Our ontologies define the domains of our news, sport and music pages
  9. 9. Our programmes archive offer • Only brand specific, bespoke archives • Expensive to create and maintain
  10. 10. ADA What about the rest of our programmes? No existing bespoke hierarchy will work for all of the topics we cover
  11. 11. But do we really want a hierarchy anyway? Just as we no longer use directories for the web, we need to look beyond hierarchies for programmes
  12. 12. Homophily and user experience Homophily (i.e., love of the same) – people like things that represent their worldview. The more links you present, the greater the trust in your links.1 1. Ilan Lobel and Evan Sadler. Preferences, Homophily, and Social Learning. In Operations Research, 2014
  13. 13. So where to find our rich set of links?
  14. 14. ADA• We used Wikipedia category information
  15. 15. ADA• Robust, crowd-verified and well maintained data
  16. 16. ADA • An average of 7 categories per concept
  17. 17. ADA • We began working with the In Our Time archive • It provides a broad and varied range of topics to explore Basic onward journeys Limited, manually curated categorisation
  18. 18. ADAIn Our Time linked data beta
  19. 19. ADA• Feedback has been positive and constructive Just a quick look delighted me … I can find all sorts of stuff I never knew existed The new beta categories database is SUPERB!! Congratulations to the programmer. Truly wonderful. Many, many thanks. Any chance applying it to other science-type podcasts ? Really ingenious – like it a lot, suggests connections, stimulates interest Thanks for arranging the categories of In Our Time. I would absolutely love TV programs to be this accessible. Not ones chosen by experts or highlights of, but all of whole series arranged so that one can follow ones own interests. This is a marvellous development! Google can be rewarding, but your development plugs us into a more manageable field of knowledge – one that’s nevertheless wide ranging and high quality. I love the joining-up. IOT's beta site is simply the single best I've experienced. Now that I have experienced it, I don't want to use the current site's format.
  20. 20. ADA • A single subject input automatically generates a wide range of categories • No need for producers to think about categories/genres Subject input ADA service processing Categories generated Connections created ADA service
