This paper describes the contributions of Vienna University of Technology (TUW) to the MediaEval 2015 Retrieving Diverse Social Images challenge. Our approach consists of 3 phases: (1) Precision-oriented-phase: in which we focus only on the relevance of the documents; (2) Recall-orientedphase: in which we focus only on the diversity aspect; (3) Merging phase: in which we explore ways to nd a balance between the relevance and diversity factors. We use two fusion methods for this last part. Our best run reached a F1@20 of 0.582.
