  1. Smart Spaces for Learning: Semantic web in a P2P learning network Sigrún Gunnarsdóttir Reserach department Nordunet 24-27. August 2003

  2. Overview • What is Elena? • Use case scenario • Project vision • Learning technology standards • Architecture • Objectives • Benefits • Facts and figuresPartners Nordunet 24-27. August 2003

  3. What is Elena? • Elena aims at creating smart spaces for learning that support the “smart” mediation of learning services based on user profiling, service evaluation and reputation ratings. • PLA, the personal learning assistant, performs the search for suitable learning services based on the learner's individual profile, processes the selected services and supports the evaluation of the learner. Nordunet 24-27. August 2003

  4. What is Elena? • Examples for a learning service are the delivery of a course, the provision of a web-based training application or self-study material. Nordunet 24-27. August 2003

  5. Smart Learning Spaces • ... are understood as peer-to-peer networks (spaces) that mediate educational services (e.g. delivery of courses or educational material) • ... take advantage of distributed user profiling in order to support the selection of educational services. Nordunet 24-27. August 2003

  6. Use Case Scenario Bob Nordunet 24-27. August 2003

  9. Metadata • Metadata is information about information and is structured in a manner that facilitates the management, discovery and retrieval of resources on the World Wide Web. • Metadata standards for the Internet are an attempt to bridge the gap between the comprehensive cataloguing which is done by professionals in the library context, and the free-for-all of document creation on the Web. Nordunet 24-27. August 2003

  10. Learner resource standards • Lom • IMS • Ariande • Dublin Core (DCMI) • Cancore • GEM • EdNa • CEN/ISSS (http://www.cen-ltso.net/Users/main.eng.aspx) Nordunet 24-27. August 2003

  11. Learner profile standards IMS LIP IEEE PAPI Nordunet 24-27. August 2003

  12. Current approaches I • Learner profile management • Distributed learner modelling (Vasileva 2002) • Each peer has learner modelling cappabilities • User modelling servers (Kobsa 2001) • Huge user profile is maintained at some kind of user modelling server • Proprietary user model databases • Based mostly on specific personalisation technique developed Nordunet 24-27. August 2003

  14. System Architecture(2) Nordunet 24-27. August 2003

  15. RDF and RDFS • Open world assumption requires RDF in order to provide means for annotating educational services, learning resources, etc. with metadata • RDF Schema is used for describing differences between concepts (RDF Schema vocabulary: class, property, subclass, type, ...) Nordunet 24-27. August 2003

  16. Issues - P2P network • Analysis showed that we have to apply a subset of more than one standard • We cannot guarantee only one modelling server with one common schema (new modelling servers can appear and disappear in P2P network) • Different personalisation techniques require different learner features and different structure of learner profile • New personalisation techniques can be introduced in the future Nordunet 24-27. August 2003

  17. Objectives • Design, implement and test a smart space for learning that integrates heterogeneous learning services • Analysis of existing standards for modeling learning-relevant data beyond learning objects and development of recommendations for their development • Derive best practice guidelines for deploying smart spaces for learning from an organisational, technological and pedagogical perspective Nordunet 24-27. August 2003

  18. Benefits … • ...for learners and organisations • Support the management of your career with Elena learning paths • Increased transparency of learning opportunities • Personalised offer of learning resources • Ease of achieving personal development goals • Targeted and personalised training for work force • Increased effectiveness of personnel development • Precise control of training budget Nordunet 24-27.
