© 2017 ACM.In this work, a three-stage social event detection (SED) framework is proposed to discover events from Flickr-like data. First, multiple bipartite graphs are constructed for the heterogeneous feature modalities to achieve fused features. Furthermore, considering the geometrical structures of dictionary and data, a dual structure constrained multimodal feature coding model is designed to learn discriminative feature codes by incorporating corresponding regularization terms into the objective. Finally, clustering models utilizing density or label knowledge and data recovery residual models are devised to discover real-world events. The proposed SED approach achieves the highest performance on the MediaEval 2014 SED dataset.
