Yovisto

Yovisto is a Web 2.0 platform to upload, share, search, tag, and to discuss academic video recordings. In addition to providing a traditional video search engine, yovisto enables the user to search within the lecture videos. Yovisto deploys innovative automated video analysis to generate a time-dependent and textbased video index for efficient retrieval. Yovisto also provides a platform for manually describing video content in a collaborative way: users can generate metadata such as keywords or labels at any position within the video (collaborative time-dependent tagging). Moreover, users can start, follow, and carry on discussions at any point within the video. Furthermore, users are able to author and maintain wiki-pages to enrich video content with supplementary information, such as images, hyperlinks, or text. The most important benefit of yovisto is its content based search facility, which allows the efficient search of yovisto’s repository (currently containing about 6000 videos of university lectures and scientific presentations) and enables the users effectively to find the information they are looking for. Yovisto started at Friedrich-Schiller-University in Jena/Germany as an ESF/BMWi (European Social Fund/German Government) funded project (called "Osotis") in 2006 with the objective to develop a video search engine for academic lecture recordings. Yovisto is now a spin-off company. The yovisto video search platform is open and free to use.
