  • Usual pitch: - data on the web = every piece of data is web addressable, so data across different places/stores/systems become linkable: the Web = 1 data space
  • Transcript

    • 3. Linked Data
      As set of principles and technologies for a Web of Data
      Putting the “raw” data online in a standard, web enabled representation (RDF)
      Make the data Web addressable (URIs)
      Link with other data
    • 4. Graph (up to date)
    • 5. So Linked Data for the OU?
      RAE
      DBPedia
      Data from
      Research
      Outputs
      OpenLearn
      Content
      ORO
      Exposed as linked data, our data interlink with each other and the external world: become part of the “global data space” on the Web
      Archive of
      Course
      Material
      Library’s
      Catalogue
      Of Digital
      Content
      geonames
      data.gov.uk
      Currently: OU public data sit in different systems – hard to discover, obtain, integrate by users.

    • 6. Why is it important?
      The OU has been the first University to expose its data as linked data: http://data.open.ac.uk
      Now widely recognized as a critical step forward for the HE sector in the UK (and worldwide)
      Favor transparency and reuse of data, both externally and internally
      Reduces cost of dealing with our own public data: integration and reuse by design
      Enable both new kinds of applications, and to make the ones that are already feasible more cost effective
      At least 3 other UK universities have now followed our example:
      http://data.online.lincoln.ac.uk/, http://data.ox.ac.uk/, http://data.southampton.ac.uk/
      And others in other countries are setting up similar initiatives
    • 7. The data.open.ac.uk Stack
      Applications
      Institutional repository data
      Research Data (Arts)

    • 18. Datasets
      Already “officially” in place:
      ORO: more than 18,000 publications from OU researchers
      Podcasts: 2,500 audio and video tracks from podcast.open.ac.uk, linked to the relate courses
      Study at the OU: more than 600 live module descriptions
      OpenLearn: more than 550 Units of course material
      KMi Staff and Planet newsletter
      Currently being processed:
      OU Buildings in MK and regional centers
      Library Catalogue
      YouTube channel
      Old Courses
      “Reading Experience Database” project
      People Profiles
    • 19. Screenshot of the dataset page
    • 20. Applications
      For education
      Mobile podcast explorer, podcast explorer on TV
      OU Building Map, OU location tracker (cf. foursquare)
      OU Expert Search
      Connecting courses/OpenLearn to relevant podcast
      OU Course Profile Facebook app using list of courses, “Study Buddy” app connecting facebook users to relevant courses

      Connection research datasets to external data
    • 21.
    • 22. Example application: Link OpenLearn to relevant course/podcasts
    • 23. Example Application: keep track of location, meetings, tutorials, at the OU
    • 24. Example application: exploring research communities
    • 25. Example application:
      Expert Search using publication information and connecting to contact information within the OU
    • 26. Example application: Explore Information about a person in the “Reading Experience Database” based on data provided by DBPedia (Linked Data version of Wikipedia)  New ways to look at humanities research data
    • 27. The future (practically)
      More data… always more data
      More links, especially to external entities
      BBC
      Government agencies
      Other universities
      More applications:
      Integration into main OU websites (e.g., study at the OU)
      Integration into common OU applications (people profile, Facebook course profile, etc.)
      Support for common OU processes (REF audit, course recommendation, providing resources to AL and lecturers)
      Sustainability
      LUCERO is finishing soon and….
      data.open.ac.uk is becoming a core component of the OU information infrastructure…
    • 28. The future (more generally)
      From nice demonstrators to real semantic web applications
      Use of reasoning and data mining for data consolidation and analysis
      Need proper frameworks for application developers!
      Linked data and the Semantic Web to support research
      Not only research communities
      Identifying new research questions and collecting evidence through connected datasets
      It is not about individual Universities!
      Universities sharing data to benefit students and researchers: the higher education’s web of linked data
      Needs collective vocabularies, recipes, approaches, classifications… the GoodRelations of higher education?
    • 29. The future (research)
      Linked data analytics/Linked data mining
      Interfaces to linked data/Making sense of linked data (with ontologies)
      Semantic web for activity data/personal data
