Yovisto

Yovisto is an academic video search engine specialized in academic content.
Overview
Yovisto's search index is based on the combination of automated content based video analysis with user generated collaborative annotation (collaborative tagging, discussions, and comments). In difference to traditional video search engines, Yovisto enables pinpoint access within video data by providing fine-granular, time-dependent metadata. For each video resource, users may author additional wiki-pages to enrich the video content with complementary (searchable) information. Yovisto metadata can be exported into the standardized and interchangeable metadata description framework MPEG-7.
Yovisto provides access to more than 7800 videos of academic lectures and scientific conferences being organized in more than 400 lecture series covering the entire spectrum of academic research. Among the more than 1100 speakers are numerous famous people such as Nobel Prize winners, and artists.
History
Yovisto started in 2006 at Friedrich-Schiller-University of Jena/Germany as an ESF/BMWi (European Social Fund/German Government) funded project (called "Osotis") with the objective to develop a video search engine for academic lecture recordings.
Yovisto search engine technology is the foundation of the multimedia processing system REPLAY at Swiss Federal Institute of Technology Zürich (ETH Zürich), and as such also part of the international Opencast Community project Matterhorn.
In March 2009 yovisto relocated from FSU Jena to Hasso Plattner Institute in Potsdam/Germany to become a research platform for semantic multimedia technologies.
