ADMRG @ MediaEval 2013 Social Event Detection

This paper elaborates the approach used by the Applied Data Mining Research Group (ADMRG) for the Social Event Detection (SED) Tasks of the 2013 MediaEval Benchmark. We participated in the semi-supervised clustering task as well as the classification of social events task. The constrained clustering algorithm is utilized in the semi-supervised clustering task. Several machine learning classifiers with Latent Dirichlet Allocation as feature selector are utilized in the event classification task. Results of the first task show the effectiveness of the proposed method. Results from task 2 indicate that attention on the imbalance categories distributions is needed.
