LABELING DEVICE, LABELING METHOD, AND PROGRAM

A labeling device (10) according to an embodiment is provided with a label candidate generation unit (11), a feature amount pair detection unit (13), and a labeling unit (14). The label candidate generation unit (11) generates a label candidate from an associated data (52) associated with a content (51). The feature amount pair detection unit (13) detects, out of combinations of feature amounts extracted from a first content and feature amounts extracted from a second content, a pair of feature amounts, which is a combination having the highest similarity between the feature amounts. The labeling unit (14) labels, as a label, a common label candidate generated from both of first associated data associated with the first content and second associated data associated with the second contentto the feature amounts that constitute the pair of the feature amounts. 实施方式的标签赋予装置(10)具备标签候选生成部(11)、特征量对检测部(13)、以及标签赋予部(14)。标签候选生成部(11)从与内容(51)相关联的关联数据(52)生成标签候选。特征量对检测部(13)在从第一内容提取的特征量和从第二内容提取的特征量的组合中，检测特征量间的相似度最高的组合即特征量对。标
