Collaborative Video Annotation for Multimedia Sharing between Experts and Amateurs

Practices in communities can be supported through a wide use of standard multimedia and web technologies. Lately, several research domains, especially cultural heritage management, have discovered the power of collaboration with amateurs in multimedia documentation work. Amateurs often carry knowledge they would be willing to contribute with small effort. Thus, there is a need for intuitive multimedia annotation tools supporting efficient collaboration among different user communities. The MPEG-7 metadata standard has been well applied to describe rich multimedia semantics. However, the complexity of MPEG-7 should rather be hidden from the user. In this paper we present the prototype of the community-aware semantic video annotation service SeViAnno based on a combination of metadata standards and Web 2.0 technologies in the cultural heritage management domain. An evaluation was carried out with amateurs and experts to explore the influence between both communities of different expertise levels.
