A workflow model for collaborative video annotation

There is a growing number of application scenarios for computer-supported video annotation and analysis in educational settings. In related research work, a large number of different research fields and approaches have been involved. Nevertheless, the support of the annotation workflow has been little taken into account. As a first step towards developing a framework that assist users during the annotation process, the single work steps, tasks and sequences of the workflow had to be identified. In this paper, a model of the underlying annotation workflow is illustrated considering its single phases, tasks, and iterative loops that can be especially associated with the collaborative processes taking place.
