  1. 1. Combining Linked Data and Mobiles Devices toimprove access to OCW N. Piedra, J. Chicaiza, J. López Universidad Técnica Particular de Loja, Loja, Ecuador E. Tovar Universidad Politécnica de Madrid, UPM Madrid Spain O M Bonastre Universidad Miguel Hernandez, Elche, Spain IEEE EDUCON 2012, Marrakesh
  2. 2. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Introduction Most of the Web content is designed for human consumption and stored in a human-understandable but not machine-readable format.
  3. 3. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Introduction Consequently, the classical Web -a Web of Documents- is evolving toward a new and promising model called Semantic Web.
  4. 4. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Introduction Philosophy of GICAC (Group of Innovation in the Quality Management of Higher Education Institutions – UPM, Spain & UTPL, Equator): Deploying Linked Open Data -particularly data of open educational materials- concerning universities, repositories, people, Open Educational Resources (OER) and Open Course Ware (OCW) from existing institutional repositories and databases, under OCW UNIVERSIA Consortium.
  5. 5. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Mobiles and EducationNew features of mobile devicespromote creation of sites calledMarkets / StoreApplications designed for mobiledevices can take advantage of otherincorporated features (camera,microphone, GPS, WIFI, etc.)
  6. 6. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Mobiles and EducationThe influence of thesedevices in education hasallowed the term "MobileEducation or MobileLearning”
  7. 7. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 ContextOpen Educational Contentand OpenCourseWareUniversia and theOpenCourseWare Consortium
  8. 8. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Context
  9. 9. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Context Using Linked Data in the OCW Context To improve discovery, accessibility, visibility and interoperability
  10. 10. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Context Using Linked Data in the OCW Context Active role of Linked Data in the OCW context. Current implementation of linked data in open educational contents as Linked OpenCourseWare Data Vocabulary (LOCWD)
  11. 11. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Context
  12. 12. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 ContextLOCWD triplestore contains RDF data of OCWcourses published by OCW-Universia networkmember countries sifting through a total of 1595OCW courses. The data model is divided intosubdomains• OCW repository properties• OCW properties• License properties• Link to datasets of interest in the LinkedOpenDatacloud.

  18. 18. Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012 Conclusions Benefit of Combination of Linked Data and mobile devices The mobile devices could produce OERs (with audio, video, photos, recommendations, etc.) and stored it in semantic repositories. The users of mobile applications can improve User Experience by consuming semantically enriched information and linked data.
