Abstract

Collaborative video annotation system is groupware system which enables a virtual community of participants to share and annotate the same digital video file from geographically dispersed nodes interconnected via the network. The video annotation process allows participants to browse videos, add, delete or update annotations. However, the existing systems are mainly concerned with the indexing, annotating, storing and sharing of video data. Hence, they only provide a basis for implementing simple way for video annotation and do not treat concurrent annotation aspects during the collaborative work. In this paper, we describe AV-Store an original method that combines both advantages of collaborative video annotation and semantic web technologies, and complies with eventual consistency condition when concurrent annotations are performed. The main idea of this approach is to define a new data type where all concurrent annotations commute. The commutativity aims at assuring the consistency of all replicas if participants perform the same sequence of annotations in different orders.
