Abstract

We are building a broadcast news video archive where topics of interest can be retrieved and tracked easily. This paper introduces a structuring method applied to the accumulated news videos. First they are segmented into topic units and then threaded according to their mutual relations. A user interface for topic thread-based news video retrieval is also introduced. Since the topic thread structure is formed so that it has fewer number of emerging links from each topic than a simple link structure of related topics, it should lessen the tedious selection during a tracking process by a user. Although evaluation of the effect of threading and user study on the interface is yet to be done, we have found the interface informative to understand the details of a topic of interest.
