Transcript

  • 1. Building the Open University’s Web of Linked Data<br />Mathieu d’Aquin and the LUCERO team <br />@mdaquin<br />Knowledge Media Institute, the Open University<br />LUCERO project <br />lucero-project.info – data.open.ac.uk<br />
  • 2. Linked Data<br />Principles and technologies for a Web of Data<br />Data objects uniquely identified by web addresses: URIs<br />A graph data model: RDF<br />For linking data objects to data objects<br />… at the scale of the Web<br />
  • 3. LOD cloud<br />
  • 4. The Open University<br />The biggest university in the UK (200,000 students)<br />One of the youngest (40 years)<br />Most teaching done at a distance<br />1 campus, 13 regional centers<br />Committed to “Open”:<br />Open educational material available as podcasts (iTunes U), units of course material (OpenLearn), etc.<br />Tradition of investing in new technology for teaching, learning, knowledge sharing, etc.<br />Role of the Knowledge Media Institute (KMi)<br />
  • 5. So Linked Data for the OU?<br />RAE<br />DBPedia<br />Data from <br />Research <br />Outputs<br />OpenLearn<br />Content<br />ORO<br />Exposed as linked data, our data interlink with each other and the external world: become part of the “global data space” on the Web<br />Archive of <br />Course <br />Material<br />Library’s<br />Catalogue<br />Of Digital<br /> Content<br />geonames<br />data.gov.uk<br />Currently: OU public data sit in different systems – hard to discover, obtain, integrate by users.<br />A/V Material<br />Podcasts<br />iTunesU<br />BBC<br />DBLP<br />
  • 6. data.open.ac.uk<br />
  • 7. The data.open.ac.uk Stack<br />Applications<br />Institutional repository data<br />Research Data (Arts)<br />Organizational infrastructure<br />Technical infrastructure<br />
  • 8. Expose<br />Store<br />Collect<br />Extract<br />Link<br />Ontologies<br />Scheduler<br />Cleaning rules<br />RDF file (add) RDF file (delete)<br />URL redirection rules<br />RSS Extractor<br />Delete (1)<br />Add (2)<br />RDF Cleaner<br />Web Server<br />ORO, podcast<br />RSS feed<br />RDF file (add) RDF file (delete)<br />Triple Store<br />RSS Updater<br />SPARQL<br />endpoint<br />RDF Extractor<br />New items<br />Obsolete items<br />Each datasets<br />Index<br />Entity Name System<br />Search<br />XML Updater<br />URI creation rules<br />Lib, courses, loc<br />Planning + Logging<br />Generic process<br />Dataset specific process<br />
  • 9. Method for a exposing a dataset<br /><ul><li> Identify data
  • 10. Get sample data
  • 11. Identify Copyright Issues
  • 12. Identify possible links
  • 13. Identify users and usage</li></ul>Initial Meeting with Data Owner<br />Lucero Core Team<br />Data Owner<br />Data Modeling sessions<br />Lucero KMi Team<br /><ul><li> Find reusable ontologies
  • 14. Map onto the data
  • 15. Identify uncovered parts
  • 16. Define URI Scheme</li></ul>Data Modeling Validation<br />Lucero Core Team<br />Lucero members<br />Data Owner<br />Development of Extractor<br />URI Creation Rules Definition<br />Deployment<br />Lucero KMi Team<br />
  • 17. Datasets<br />Already “officially” in place:<br />ORO: more than 18,000 publications from OU researchers<br />Podcasts: 2,500 audio and video tracks from podcast.open.ac.uk, linked to the relate courses<br />Study at the OU: more than 600 live module descriptions<br />OpenLearn: more than 550 Units of course material<br />KMi Staff and Planet newsletter<br />Open Arts Archive<br />Currently being processed:<br />OU Buildings in MK and regional centers<br />Library Catalogue<br />YouTube channel<br />Old Courses<br />“Reading Experience Database” project <br />People Profiles<br />
  • 18. Links and Vocabularies<br />We link to<br />Geonames for course availability<br />Education.data.gov.uk to reuse their representation of the Open University<br />Data.ordnancesurvey.gov.uk for postcodes of OU buildings<br />Dbpedia.org for Arts History dataset<br />We almost only reuse vocabularies:<br />BIBO for publications<br />FOAF for people<br />Dublin Core for a lot of things<br />W3C Ontology for Media Resources for podcasts and Youtube videos<br />LODE (linkedevents) for events<br />MLO and XCRI for course description<br />GoodRelations for prices and offers<br />AIISO for organizational structure<br />And connect taxonomies<br />The Local Open University topic categories<br />The iTunes U categories<br />The Library of Congress Subject Headings<br />JACS codes<br />
  • 19. Screenshot of the dataset page<br />
  • 20. Applications<br />For education <br />Mobile podcast explorer, podcast explorer on TV <br />OU Building Map, OU location tracker (cf. foursquare)<br />OU Expert Search<br />Connecting courses/OpenLearn to relevant podcast<br />OU Course Profile Facebook app using list of courses, “Study Buddy” app connecting facebook users to relevant courses<br />For Research<br />Display connections in a research community<br />Research Data/Impact Analysis<br />Connection research datasets to external data <br />
  • 21.
  • 22. Example application: Link OpenLearn to relevant course/podcasts<br />
  • 23. ROLE widget<br />
  • 24. Example Application: keep track of location, meetings, tutorials, at the OU<br />
  • 25. Example application: exploring research communities<br />
  • 26. Example application:<br />Expert Search using publication information and connecting to contact information within the OU<br />
  • 27. Lean-back podcast viewer<br />
  • 28. 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<br />
  • 29. Where this is going<br />More and more integration at the OU:<br />Link to podcasts, iTunes U, Youtube on course pages in Study at the OU (Comms/Student Services/IT)<br />Use in the “Course profile” Facebook Application (IT/Comms)<br />RADAR: research audit/assessment using linked data (KMi[Vanessa]/Research School)<br />Mobile Course/Qualification explorer (Comms)<br />OU Events in RDFa (Comms)<br />
  • 30.
  • 31. Integrating Open Educational Material in course descriptions<br />
  • 32. Radar<br />
  • 33. Explore <br />Explore the courses, qualifications and open educational resources available on a particular topic in one place.<br />
  • 34. Why is it important?<br />The OU has been the first University to expose its data as linked data: http://data.open.ac.uk<br />Now widely recognized as a critical step forward for the HE sector in the UK (and worldwide)<br />Favor transparency and reuse of data, both externally and internally<br />Reduces cost of dealing with our own public data: integration and reuse by design<br /> Enable both new kinds of applications, and to make the ones that are already feasible more cost effective<br />Many other UK universities have now followed our example: <br />Lincoln, Southampton, Edinburg, Oxford, …<br />And others in other countries are setting up similar initiatives (Muenster, Loja, UPM, CNR…)<br />
  • 35. Where this is going<br />Linked data across universities<br />More and more UK and European university creating their linked data platform (following us!)<br />Towards data.ac.uk?<br />LinkedUniversities.org – providing common vocabularies and tools so that linked data from different universities can integrate <br />Aggregation of video material from Open Educational Repositories<br />Major Challenge: Common/linked categorization scheme and tag space<br />Integration with Schema.org/LRMI<br />
