我们正在建立一个广播新闻视频档案，可以很容易地检索和跟踪感兴趣的话题。本文介绍了一种应用于积累的新闻视频的结构化方法。首先，它们被分割成主题单元，然后根据它们之间的相互关系进行分类。介绍了一种基于主题线索的新闻视频检索用户界面。由于主题线索结构的形成使得来自每个主题的出现链接的数量少于相关主题的简单链接结构，因此它应该减少用户在跟踪过程中的繁琐选择。尽管对线程化效果的评估和用户对界面的研究尚未完成，但我们发现该界面有助于理解感兴趣的主题的细节。
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 thenthreadedaccording 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.
