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

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”
