This paper provides a description of the MediaEval 2013 Placing Task. The primary task of location estimation asks participants to place images on the world map, that is, to automatically estimate the latitude/longitude coordinates at which a photograph was taken. The newly introduced secondary task of placeability prediction asks participants to estimate the error of their predicted location. Annotating images with this kind of geographical location tag, or geotags, has a number of applications in personalization, recommendation, crisis management and archiving. Currently, the vast majority of images online are not labelled with this kind of data. This task encourages participants to find innovative ways of automatically geo-labelling images while at the same time providing a measure of their algorithm’ accuracy. This year’s data were drawn from Flickr. In comparison to previous editions of this task, the test set has not only increased drastically in size but has also been derived according to different assumptions in order to model a more realistic use-case scenario.
