Abstract(in English) | In recent years, methods for calculating semantic distance between various concepts from a set of tagged images have been actively studied due to their applicability to image retrieval, clustering, annotation, and so on. Most of the existing distance calculation methods can be divided into two categories: the methods based on tag co-occurrence and those based on visual features extracted from the images. The former has a drawback that two similar concepts do not necessarily co-occur as text tags even if they are concurrently presented in an image. On the other hand, the latter has a drawback that visual features do not correspond directly to semantic meaning of concepts due to the semantic gap, especially in the case with abstract concepts. To overcome these drawbacks, in this paper, we propose to combine the above two types of methods by adaptively weighting each of them according to the level of abstraction for each concept. In our experiments, our proposed method outperformed the methods using only either tag co-occurrence or visual features. |
