1. VideoLectures.NET is a large online portal hosting over 18,500 educational videos from 11,900 authors and receiving 10,000 unique visitors per day. 2. The VideoLecturesMashup project aims to semantically enrich video content to allow users to search for and retrieve specific topics, fragments, and curriculums from the video library. 3. The MediaMixer project provides tools to analyze, annotate, and semantically tag video content to facilitate improved search and assembly of video fragments into meaningful sequences for on-demand learning.

• Aims

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!
