    • A metadata augmentation system determines similarities between digital objects, such as digital videos, that may or may not have metadata associated with them. Based on the determined similarities, the metadata augmentation system augments metadata of objects, such as augmenting metadata of objects lacking a sufficient amount of metadata with metadata from other objects having a sufficient amount of metadata.In one embodiment, the similarities are used to determine training sets for training of classifiers that output degrees of more specific similarities between the corresponding video and an arbitrary second video. These classifiers are then applied to add metadata from one video to another based on a degree of similarity between the videos, regardless of their respective locations within the object similarity graph.
    • 元数据增强系统确定数字对象(例如数字视频)之间的相似性,其可以或可以不具有与其相关联的元数据。 基于确定的相似性,元数据增加系统增加对象的元数据,例如用具有足够量的元数据的其他对象的元数据来增加缺少足够数量的元数据的对象的元数据。 在一个实施例中,相似性用于确定用于训练分类器的训练集,其输出对应视频和任意第二视频之间的更具体相似度的度数。 然后,这些分类器可以基于视频之间的相似程度,将元数据从一个视频添加到另一个视频,而不管其在对象相似图中的相应位置如何。
