We introduce the VideoLecturesMashup, which presents re-mixes of learning materials from the VideoLectures.NET portal based on shared topics across different lectures. Learners need more efficient access to teaching on specific topics which could be part of a larger lecture (focused on a different topic) and occur across lectures from different collections in distinct domains. Current e-learning video portals can not address this need, either to quickly dip into a shorter part focused on a specific topic of a longer lecture or to explore what is taught about a certain topic easily across collections. Through application of media technologies promoted by the MediaMixer project – semantic annotation and media fragment URIs – we have implemented a first demo of VideoLecturesMashup.

4. 14.02.13 Slide 4 of 40
Media creation & re-use in
e-learning
4
• E-learning materials are increasingly
multimedia: more video recordings, more
accompanying materials such as slides
– E-learners need to be able to search
and retrieve the material they are
looking for (based on its subject)
– Consumption trends towards mobile and
on-the-go means interest focuses on
the parts of the material of
particular interest

Current USER workflow

7. 14.02.13 Slide 7 of 40
Problems
• Search (text matching only over titles, descriptions)
• Users looking for learning materials on specific topics -
unique requirements
• Users looking for very specific information - fragments, not
entire lectures
• Lack of time for watching, the need for mobile version
• The need for meaningful structures, curriculums
• Videolectures.NET strategy includes continuous
introduction of new technologies - important initiative to
provide users with access to the semantically enriched
content fragments...

Current CM workflow

9. 14.02.13 Slide 9 of 40
Problems
• From manual to automatic
• Save CM‘s time, employer money
• The need for new functionalities
(automatic textual transcriptions from speaker audio,
translations (FP7 transLectures), concept extraction from
slides (not just titles but textual content), video analysis,
semantic annotation - video annotation process,
segmentation...)
• Manually make meaningful structures, curriculums (takes
too much time!)

10. 14.02.13 Slide 10 of 40
Benefits from new technology
10
• Simplify existing workflows
• Improved search and browsing in general and retrieval of fragments
• Fragments of learning materials from the site, ordered in a meaningful way
• Content on demand; easier and quicker access to specific topics of interest
• Direct intuitive access to a single learning channel built around the topic
searched for
• Producing new learning materials - curriculums
• Content specifically addressable and hence bookmarkable/saveable for
subsequent reference and viewing
• New contexts -> dynamic provision of such learning resource would be
particularly useful in mobile consumption contexts
• These could subsequently form new distribution channels for VideoLectures
(e.g. video streams / TV channels on selected topics)
• This could drive to more repeated access and win new users!
