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.

  • 1 VideoLecturesMashup Tanja Zdolšek, Jožef Stefan Institute + VideoLectures.NET & Lyndon Nixon, MODUL University Vienna GmbH April 24, 2014. OCWC Global, Ljubljana, Slovenia
  • 14.02.13 Slide 2 of 40 • Start: support service • Now: largest web portal with video edu&open access • 18.500 videos (1- 1,5h) • 11.900 authors • 10.000 unique visitors/day
  • 14.02.13 Slide 3 of 40 Facts • Informal learning channel • Promoting science, fostering knowledge • OER • Mobility • Award-winning • UN WSA for „e-science & technology“ • 2009 – WSA, 2013 – WSA of the decade • Aims
  • 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

  • 14.02.13 Slide 6 of 40 Current USER workflow
  • 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...
  • 14.02.13 Slide 8 of 40 Current CM workflow
  • 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!)
  • 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!
  • 14.02.13 Slide 11 of 40 MediaMixer Project and VideoLectures MashUpHow media fragments and their re- mixing can enable new experiences for e- learners
  • 14.02.13 Slide 12 of 40 The MediaMixer hub • Video analysis tools • Video annotation tools • Video metadata creation and publication • Digital rights management • Media search and retrieval • Media negotiation, purchase and re- use
