1. Bringing Linked Data to SocialLearn Mathieu d’Aquin - KMi

2. Linked Data As set of principles and technologies for a Web of Data Putting the “raw” data online in a standard representation (RDF) Make the data Web addressable (URIs) Link with to other Data

4. Linked Data at the OU (the LUCERO Project) RAE DBPedia Data from Research Outputs OpenLearn Content ORO Archive of Course Material Library’s Catalogue Of Digital Content geonames data.gov.uk A/V Material Podcasts iTunesU BBC DBLP

5. Linked Data at the OU (data.open.ac.uk)

6. SocialLearn in Linked Data RAE DBPedia SocialLearn Data (Users, activities, Learning Paths, etc.) Data from Research Outputs SocialLearn Private Space OpenLearn Content ORO Archive of Course Material Library’s Catalogue Of Digital Content geonames data.gov.uk A/V Material Podcasts iTunesU BBC DBLP

7. A linked data interface to SocialLearn data Exposing the content of the SocialLearn database according to linked data principles Establish URIs for SocialLearn objects (users, events, learning paths, notes, etc.) Represent relationships in this database through links (e.g., learning path –author-> user) Expose this data through a SPARQL endpoint Realized through D2R (database 2 RDF), mapping SPARQL queries to SQL in real time

8. URIs and labels of Learning Paths that are owned by user 140 Results. Each URI represent an addressable and queryable piece of data

9. Linking up Users Events Learning Paths Groups Media SocialLearn Linked Data Graph Data.open.ac.uk linked data graph and beyond

10. Traverse to recommend related things Podcast “John Napier's mathematical creations” Learning Path 7359

11. Traverse to recommend related things Users Events User 140 Course L204 Learning Paths Groups Media

12. A generic linked data based recommendation service SocialLearn SPARQL endpoint Links SPARQL endpoint Data.open.ac.uk SPARQL endpoint URI of origin resource SocialLearn REST Recommendation Service URIs of related resources URI of User Filters

16. Next Steps Integration with SocialLearn environment More links, more data Improve runtime performance Personalization Recommendations filtered and rank depending on the user, on the popularity of resources, on the learning history…
