Abstract

We introduce a method to extract topic threads throughout a large-scale news video corpus as well as an interface that provides the users with the facility to browse through the corpus guided by the thread structure. The thread-based interface enables thorough understanding of a topic of interest, and moreover, it is designed to reduce the number of candidates provided during the tracking process which lightens the burden of selection imposed on the users. In this paper, we introduce the details of topic segmentation, tracking/threading, followed by the evaluation of the segmentation and the introduction of a prototype interface. The evaluation showed practical ability, and the trial use of the interface turned out to be effective and informative.
