Transcript

  • 1. Metadata om te creëren Automatisch Nieuwsproductie Robbie De Sutter MediaNet Vlaanderen 3 december 2008 © VRT-medialab: onderzoek en innovatie
  • 2. Introduction – Making the News 2 © VRT-medialab: onderzoek en innovatie
  • 3. Dopesheets Information on the news story  Description content (who, what, where, when, …)  Administrative information (reporter, cameraman, …)  Rights information (usage terms, copyright statement, …)  Technical information (video format, audio format, …) … Initially: plain text (cf. telex) Currently: proprietary structured text (XML, e.g. NMS) Future: international standardized structured text (XML) IPTC’s NewsML-G2 3 © VRT-medialab: onderzoek en innovatie
  • 4. Telex 4 © VRT-medialab: onderzoek en innovatie
  • 5. Dopesheet Examples 5 © VRT-medialab: onderzoek en innovatie
  • 6. NewsML-G2 International (industrial) standard approved by IPTC (shortened) Timeline  1997: NITF  2000: NewsML 1.0, 1.1, 1.2 (too complicated and ineffective)  2008: NewsML-G2 Objectives NewsML-G2: Interoperability between providers and consumers  Extensibility  Clarity and compactness of the syntax  Ease of storage  Ease of processing for relational or object mapping  New focus on “semantic” capabilities (Web 2.0 ready)  6 © VRT-medialab: onderzoek en innovatie
  • 7. Taxonomie references 1 News Item (~ 1 dopesheet ~1 news story) Rights information (accountable, copyright holder, usage terms) Item management (version management, provider, role, title, web ref.) Administrative Data (content created, creator, contributor, audience) Descriptive Data (language, genre, subject, headline, slugline, dateline, by, description) Parts of an Item Concept Definitions and (shots, scenes, image regions) Concept Relations contains descriptive data and time boundaries (named entities and abstract concepts – Person/organisation details, geopolitical area, POI) Alternative renditions (inline XML, inline/remote Data) 7 © VRT-medialab: onderzoek en innovatie

  • 10. Automatic News Production NewsML-G2 handling Parsing + transcoding EBU SuperPop News Clips MAM Vodcast VRT iNews Rundowns Personalized News Production 10 © VRT-medialab: onderzoek en innovatie
  • 11. Automatic News Production Now @ VRT:  Classical broadcast: linear, 5 broadcasts a day  On-demand (“ooit gemist”): replay of the linear broadcasts  Web (“deredactie.be”): news clips, continuous updates Linear broadcasts have a rigid structure  E.g., 19h news – Max 20 news items – Max 40 minutes More content available than broadcasted  News feeds (EBU/Eurovision, Reuters, …)  Produced items never or only a few times broadcasted 11 © VRT-medialab: onderzoek en innovatie
  • 12. Goals Enable a news consumer to compose his own news programme  Select only the news categories he is interested in – e.g., national weather, international business, …  Sort the news categories according to his personal relevance – e.g., first sport, then business, then politics  Specify the maximum duration of the news – e.g., his commuting time is 30 minutes, so 30 minutes of news  Let him choose to receive unedited (“raw”) news materials/feeds – e.g., every news items about science & technology  Let him watch the news items offline – e.g., play his news on a mobile device, such as iPod Touch Without interfering with current news production processes 12 © VRT-medialab: onderzoek en innovatie

  • 21. Final remarks By intelligently processing the available metadata automatic personalized news bulletin generation is feasible However, some “gaps”  IPR management (now: free text – no automatic usage approval)  category assignment for VRT news items  item versioning (linking items) Tools might solve some of these gaps 21 © VRT-medialab: onderzoek en innovatie
