Successful CERTH participation in the Social Event Detection task @ MediaEval 2011
CERTH-ITI successfully participated in the Social Event Detection task of the MediaEval 2011 workshop. MediaEval, a workshop focused on focused evaluation tasks with respect to multimedia analysis, took place in Pisa, Italy (1-2 September 2011). CERTH took part in the Social Event Detection (SED) task that involved two challenges: (a) detection of soccer events in two major European cities, (b) detection of events taking place in two specific venues. Both challenges were defined on a large set of about 75000 images from Flickr. A more detailed definition of the task is available here.
In the first challenge, CERTH achieved the best results, while in the second one its performance was close to the median. The approach employed by CERTH is described here, while the presentation given at the workshop is embedded below. We have also made available the implementation of the approach in the form of a Java library. You can read more details here.
