Zenaminer: driving the SCORM tandard towards the Web of Data

  1. 1. Zenaminer: driving the SCORM standard towards the Web of Data E. Mudu, L. Schiatti, G. Rizzo, A. Servetti Heraklion, May 29 Linked Learning 2011
  2. 2. Agenda• Idea• SCORM specifications and structure• LMS: state of the art• Proposal• Conclusions• PerspectivesMay 29 Linked Learning 2011 02
  3. 3. Idea SCORM player able to publish SCOs into the Web of Data Allow the creation of customized Web interface for SCORMs Allow the migration of SCOs into the Web of Data where a “consumer” can infer, connect and aggregate data from different repositoriesMay 29 Linked Learning 2011 03
  4. 4. Why SCORM?Its one of the most used standard packaging ofe-learning contentsPotentially many SCORM objects are spread withinthe WebPossibility to introduce and link them in the LinkedData cloudMay 29 Linked Learning 2011 04
  5. 5. SCORM structure SCORM object defines how a course is organizedIt provides a tree structureSCO is a minimal reusableand shareable partMay 29 Linked Learning 2011 05
  6. 6. SCORM exampleMay 29 Linked Learning 2011 06
  7. 7. Learning ManagementSystem: state of the art LMS SCOMay 29 Linked Learning 2011 07
  8. 8. LMS: limitations✗ SCO designer cannot control all the graphicalinterface used but only the space dedicatedfor the SCO✗ Difficult to integrate more information (text,video, … )✗ Contents and presentation are mixed, hard toadapt the interface for different devices(smart phone, tablet, notebook)May 29 Linked Learning 2011 08
  9. 9. Goal Publish educational Link automatically data into the Web comments to Web of Data resources RESTful application to implement these featuresMay 29 Linked Learning 2011 09
  10. 10. RESTful architectureMay 29 Linked Learning 2011 10
  11. 11. Publish educationaldata• SCORM objects are sent to the REST controller• REST controller elaborates data each object and exports all raw data (text information) form• Then it publishes raw data, allowing users to build their preferred layoutMay 29 Linked Learning 2011 11
  12. 12. POST /scormsMay 29 Linked Learning 2011 12
  13. 13. Demos of customized viewsMay 29 Linked Learning 2011 13
  14. 14. Link comments to WebresourcesTo allow collaborative learning, Zenaminerconsiders all text comments edited by a useras a learning enrichment and shares themwith all the users in a wiki styleMay 29 Linked Learning 2011 14
  15. 15. Looking towardsLinked DataEach comment is annotated by means of aDBpedia SpotlightDBpedia Spotlight✗ extracts one named entity for each comment✗ maps each comment to a DBpedia resourceMay 29 Linked Learning 2011 15
  16. 16. POST /commentMay 29 Linked Learning 2011 16
  17. 17. ConclusionsPublication of SCORM contents in the Web of Dataas raw data separating the content from thelayout. Any SCO designer is free to choose ordesign his preferred viewAutomatic annotation for the integration ofcontents with hypertext link navigation in order tosatisfy more effectively the information needs ofthe learnerMay 29 Linked Learning 2011 17
  18. 18. PerspectivesVocabulary for SCORM and URI schemaFragmentsEvaluation of those systemsAttach provenance/licence to SCOsMay 29 Linked Learning 2011 18
