- 16. Translectures Our aim is to develop innovative, cost-effective solutions to produce accurate transcriptions and translations in VideoLectures, with generality across other Matterhorn-related repositories. Three scientific and technological objectives: • Improvement of transcription and translation quality by massive adaptation. • Improvement of transcription and translation quality by intelligent interaction. • Integration into Matterhorn to enable real-life evaluation. 4 June 2013 17
- 17. Results Freely available tools and services for accurate transcriptions and translations: - Automatic transcription of videos: English, Slovenian, German, French, Spanish - Automated translation of videos: en⇆es, en⇆sl, en fr and en de. Initial implementation: - Videolectures - poliMedia - Matterhorn 18

- 26. Media fragments Media mixing is the process by which self-contained parts of media (fragments) are identified and exposed via media repository interfaces, so that consumers can access and re-use only the parts they are interested in. Media Mixer Hub AV Content Provider (1-n) AV Content Demander (1-m) 1) AV material analysis and annotation 2) Fragment Definition 3) Rights and Cost Assignment 6) Search. Browsing 7) Rights and Cost Assessment 8) Download 4) Fragment Upload 5) Clearing (Sell) 9) Composition of new AV materials 10) Clearing (Buy) annotated & linked Media Fragments
- 27. Mediamixer (http://mediamixer.eu/) • Community set-up and networking for the reMIXing of online MEDIA fragments • to set up and sustain a community of video producers, hosters, and redistributors who will be supported in the adoption of semantic multimedia technology in their systems and workflows to build a European market for media fragment re-purposing and re-selling. • http://community.mediamixer.eu/
