  2. 2. Intro & Motivation • Quiz-based Technology-Enhanced Learning • Powerful for both learning and assessment • But also time-consuming, expensive • Plenty of Linked Open Data available • Exploitable in online courseware • Suitable for new learning and assessment materials • Linked Data limitations (addressed by the approach): 1. Re-use and Adoption • User-friendly layer of learning and assessment artifacts on top 2. Data Quality • Through Games With A Purpose approach 2
  3. 3. LDMQ – Linked Data + Quizzes Linked Data Movie Quiz Cinema questions by SPARQLing the Linked Movie DataBase Ack: @jorgelamb + @numeroteca are-out-there-and-so-are-the-questions/ 3

  5. 5. LDMQLimitations & Beyond• Questions generated in an ad hoc manner (predefinedSPARQL queries + some JS)  Templates tooling supporting experts• Over a single endpoint  Use several datasets• No persistence of the questions  Expose Quizzes as new dataset(s)• Not leveraging user interactions Analyse mistakes and let them “flag” 5
