  • Abstract:

    This paper describes the participation of the SosialSensor team in the Retrieving Diverse Social Images Task of MediaEval 2014. All our entries are produced by a different instantiation (set of features, parameter configuration) of the same diversification algorithm that optimizes a joint relevance-diversity criterion. All our runs are automated and use only resources given by the task organizers. Our best results in terms of the social ranking metric (F1@20 ~ 0.59) came by the runs that combine visual and textual information, followed by the visual-only run.
