本文描述了一种浏览大量视频集合的新方法。它将各种形式的相关视频片段作为线索链接在一起。这些线索基于查询结果、时间线以及视觉和语义相似性。我们设计了两个以线程作为浏览基础的界面。一个界面显示了最小的线程集，而另一个界面显示了屏幕上可以容纳的所有线程。为了评估这两种界面，我们进行了定期的用户研究，这是一项基于用户模拟的研究，我们还参与了TRECVID基准测试的交互式视频检索任务。结果表明，线程在交互式视频检索中的应用是有益的。此外，我们发现，通常情况下，查询结果和时间线是最重要的线程，但拥有几个额外的线程可以提高性能，因为它鼓励人们探索新的维度。
This paper describes a novel method for browsing a large video collection. It links various forms of related video fragments together as threads. These threads are based on query results, the timeline as well as visual and semantic similarity. We design two interfaces which use threads as the basis for browsing. One interface shows a minimal set of threads, and the other as many as fit on the screen. To evaluate both interfaces we perform a regular user study, a study based on user simulation, and we participated in the interactive video retrieval task of the TRECVID benchmark. The results indicate that the use of threads in interactive video retrieval is beneficial. Furthermore, we found that in general the query result and the timeline are the most important threads, but having several additional threads improves the performance as it encourages people to explore new dimensions.
