Infomedia 数字视频库包含超过 2000 小时的视频,并且以每周 15 小时的速度增长。良好的查询引擎不足以进行信息检索,因为候选结果集的数量通常会随着库的增长而增长。视频摘要总结了图书馆中的故事集,为用户提供了交互式浏览和查询细化的可视化机制。这些摘要是在用户的指导下根据从视频库自动导出的元数据动态生成的。讨论了三种类型的摘要:强调单词关系的 VIBE 摘要、显示时间趋势的时间线以及显示地理相关性的地图。多个摘要可以组合成单个视图或动画成临时演示。
The Informedia Digital Video Library contains over 2000 hours of video, growing at a rate of 15 hours per week. A good query engine is not sufficient for information retrieval because often the candidate result sets grow in number as the library grows. Video digests summarize sets of stories from the library, providing users with a visual mechanism for interactive browsing and query refinement. These digests are generated dynamically under the direction of the user based on automatically derived metadata from the video library. Three types of digests are discussed: VIBE digests emphasizing word relationships, timelines showing trends against time, and maps showing geographic correlations. Multiple digests can be combined into a single view or animated into a temporal presentation.
