XML-based video annotation system for language learning environment

This paper focuses on XML-based video annotation system for language learning using videoconference system. The environment supports between native speaker as teacher and non-native learner We extend videoconference system so the system can record learning scene as video poundle. Learning scene recorded in the videoconference system can use for educational instruction. For instance, teacher can explain by, inserting feedback as annotation in the scene. If teacher edits the video to explain, it is very, useful as teaching materials. However ordinal video editing system creates quite a new video file so it cannot change the contents for playback. In addition, learner can hardly, grasp teacher's task. Therefore, we propose Video Correction and VCML (Video-based Correction Markup Language) based on XML to represent corrected information. We call the prototype Viclle ( Video-based Communicative Language Learning System). With the system, both teacher and learner can communicate via e-mail without sending video files. In addition, video correction resembles to retrieve information from database with keywords. Therefore, Viclle is regarded as an error database.
