The task uses the MediaEval 2012 Tagging Task (ME12TT) dataset, an extension of the original MediaEval 2010 Wild Wild Web Tagging Task dataset used in previous tasks. In this task overview paper, we describe the principal characteristics of the data set, the task itself, and the evaluation metrics used to test the participants´ results.} }
