Social Event Detection (SED) 2014 dataset

on .

Overview: This page provides pointers to the dataset, challenge definitions, ground truth challenge results and corresponding evaluation script that were created and used in the 2014 edition of the Social Event Detection (SED) task of the MediaEval benchmarking activity.

The Social Event Detection (SED) task of MediaEval 2014 contained required participants to a) cluster a collection of images so that the images in each cluster are associated with a distinct social event and b) given a collection of images / clusters corresponding to social events, to retrieve those that match specific criteria. By social events, we mean that the events are planned by people, attended by people and that the media illustrating the events are captured by people. Each image in the dataset is accompanied by metadata typically found on the social web (including time-stamps, tags, geotags for a small subset of them).
