  • 4. journalists „tagging‟ annotating (“tagging”) content tool embedded into CMS concept extraction/NLP for topic suggestion journalists accept/reject suggested topics
  • 5. pilot – location tagging it worked… except when big stories broke we write several articles about the same storyline
  • 6. articles… storytelling is fragmented manual linking decays massive amount of repetition
  • 7. from articles to storylines develop a data model to describe a news storyline and its topics refine our content model to handle granular updates (A/V clip, short-form, social media update, long-form) ask journalists to annotate („tag‟) these updates with their storyline
  • 8. collaborative model development
  • 9. www.purl.org/ontology/storyline
  • 10. www.purl.org/ontology/storyline
  • 11. www.purl.org/ontology/storyline
  • 12. www.purl.org/ontology/storyline
  • 13. an example storyline
  • 14. linking storylines
  • 15. linking events
  • 16. tag storylines with topics…
  • 17. topics topics are real-world entities, or things people organisations places themes
  • 18. people a Person can have properties like „birth-place‟, „birth-date‟, and roles like „President of Syria‟ or „interpreter‟ Thamsanqa Jantjie Nick RobinsonLara Clarke Bashar al-Assad
  • 19. organisations an Organisation can have properties like „address‟, „website‟, and can be notably associated with a person, place or theme
  • 20. places Places can have a latitudes/longitudes and parent features (an administrative district or country for example)
  • 21. themes Themes are the intangible things that we might want to classify our content by: „smoking‟, „unemployment‟, „health‟ health unemployment smoking
  • 22. tagging with a topic <:thing> :type <:video> <:thing> :about <:David Cameron> but is this video clip really about the topic of David Cameron?
  • 23. about-ness?
  • 24. tagging with a storyline <:thing> :type <:video> <:thing> :about <:storyline> <:storyline> :slug “Cameron EU statement” <:storyline> :topic <:David Cameron> <:storyline> :topic <:European Union> <:storyline> :attribution <:Nick Robinson>
  • 25. topics connect storylines
  • 26. curation vs automation two ways to present tagged content: automatic aggregations where all content tagged with that storyline, event or topic is included in a chronological stream manual curations where a journalist picks and orders content in order to tell a particular story
  • 27. automatic aggregation
  • 28. anything with that storyline or topic tag automatically surfaces it in that stream this could be the default/out-of-hours state for a storyline or topic page less time-consuming, but no control over tone and sequence automatic aggregation
  • 29. manual curation
  • 30. more time consuming, but greater control candidate content is manually selected for inclusion in a storyline or topic page attribution – manually curated storylines can be attributed to a person or group (internally or publicly) manual curation
  • 31. demo? production tagging with topics and storylines live pilot of storyline tagging in the Midlands
