Comparison of multimodal annotation tools - workshop report

Abstract In recent years, dozens of tools have become available for annotation of digital audio-video data. For a researcher looking for an annotation tool, it is difficult to decide about its usefulness and usability. In this paper, essential information about some of the available tools is summed up as a result of a workshop at which developers, user experts, and researchers interested in using these tools met. At this forum, these tools’ strengths and weaknesses for specific annotation and analysis purposes were discussed.
