The usefulness of multimedia surrogates for making relevance judgments about digital video objects
作者：
Highlights：
• Storyboard, 7-second segment, and fast forward video surrogates were equally effective in supporting users in making accurate relevance judgments.
• Storyboard surrogates were the most efficient to use, but many participants chose to use multiple surrogates when they were available.
• The fast forward surrogate or a combination of all three surrogates was preferred by video collection users.
• Developers of video collections should consider providing multiple surrogates, each providing a different view of the video content and/or style.
