                         It differs from the existing works of violence detection in what 
                         concern the data representation, as none has considered local 
                         spatio-temporal features with bags of visual words. An evaluation 
                         of the importance of local spatio-temporal features for 
                         characterizing the multimedia content is conducted through the 
                         cross-validation method. The results obtained confirm that motion 
                         patterns are crucial to distinguish violence from regular 
                         activities in comparison with visual descriptors that rely solely 
                         on the space domain.",
