Exploiting User-Supplied Tags for Flickr Photos Annotation

The popularity of photo-sharing websites like Flickr gives one a chance to observe what ordinary users do in their daily life. Particularly, Flickr allows the users to provide personalized tags when uploading photos, and then one can annotate Flickr photos using user-supplied tags. This paper proposes an approach to automatically annotate Flickr photos by exploiting user-supplied tags. User-supplied tags are submitted to Wikipedia to prune noisy tags, and then the reserved tags are denoted as initial tags. Afterwards, the initial tags are ranked using manifold-ranking algorithm, by which regions of the photo to be annotated are served as queries to launch the manifold-ranking algorithm which ranks the initial tags according to their relevance to the queries.
