    • A system, method and various user interfaces enable visually browsing multiple groups of video recommendations. A group of video recommendations includes a central video and a set of related videos displayed at its corresponding display distance from the central video and from each other. The corresponding display distance of a video is calculated as a function of the video's recommendation score and correlation with other videos of the group. The recommendation score is generated based on a weighted covisitation measure. Visually presenting recommended videos to a user provides a quick and intuitive way to find videos of interest and visualize the browsing of the recommended videos.
    • 系统,方法和各种用户界面可视觉浏览多组视频推荐。 一组视频推荐包括一个中央视频和一组相关的视频,以与中央视频相对应的显示距离显示。 视频的相应显示距离是根据视频的推荐得分计算的,并且与该组的其他视频相关。 推荐评分是根据加权的参与度量产生的。 向用户呈现推荐视频,可以快速直观地查找感兴趣的视频,并可视化推荐视频的浏览。
