Abstract: | In this paper we present an automatic photo tag expansion method designed for photo sharing websites. The purpose of the method
is to suggest tags that are relevant to the visual content of a given photo at upload time. Both textual and visual cues are
used in the process of tag expansion. When a photo is to be uploaded, the system asks for a couple of initial tags from the
user. The initial tags are used to retrieve relevant photos together with their tags. These photos are assumed to be potentially
content related to the uploaded target photo. The tag sets of the relevant photos are used to form the candidate tag list,
and visual similarities between the target photo and relevant photos are used to give weights to these candidate tags. Tags
with the highest weights are suggested to the user. The method is applied on Flickr (). Results show that including visual information in the process of photo tagging increases accuracy with respect to text-based
methods. |
