Description
The Social Even Detection (SED) task is part of the MediaEval annual international benchmarking activity. In the 2012 edition of the SED task, three event-related challenges were defined on a common dataset of approximately 167k images. All three challenges required that participants detect images related to specified classes of events, and return them clustered in different events.
In order to further promote research in event-related media organization and facilitate the comparison between different approaches on a common dataset, the SED 2012 dataset has been made publicly available for download and use by the research community. The downloadable archives include the following: a) The three 2012 SED Challenges definitions, b) The XML metadata for the images in the test dataset, c) The actual image files of the test dataset, d) Ground truth results for the defined challenges/dataset, e) An evaluation script.
