Our ICME 2013 paper “An evaluation of nearest-neighbor methods for tag refinement” by Tiberio Uricchio, Lamberto Ballan, Marco Bertini and Alberto Del Bimbo is now available online.

The success of media sharing and social networks has led to the availability of extremely large quantities of images that are tagged by users. The need of methods to manage efficiently and effectively the combination of media and metadata poses significant challenges. In particular, automatic image annotation of social images has become an important research topic for the multimedia community. In this paper we propose and thoroughly evaluate the use of nearest-neighbor methods for tag refinement and we report an extensive and rigorous evaluation using two standard large-scale datasets.
