Call for Participation in the Placing task (Geotag Prediction for Videos)
MediaEval 2010 Benchmark Evaluation

MediaEval 2010 is offering a "Placing task" involving automatic 
prediction of location (geotags) for a
set of Flickr videos based on provided textual tags and visual features. 
Groups interested in participating
can sign up by 31 May 2010 at The data 
set contains a set of geotagged
Flickr videos (~10,000 for development and test purposes) and the 
metadata for geotagged Flickr
images (~3.5 million). We also provide a set of basic visual features 
extracted for all images and for
the frames of the videos. Evaluation of runs submitted by participating 
groups will be based on distances
between the predicted and the actual geo-coordinates. Ground truth is 
supplied by Flickr users
uploaded the videos and the images. All videos and images are shared by 
their owners under Creative
Commons license.

MediaEval is a benchmarking initiative that offers tasks promoting 
research and innovation on
multimodal approaches to multimedia access and retrieval. MediaEval 2010 
(which builds on and
expands VideoCLEF 2008-2009) focuses on speech and language, but also 
visual and social features.
Participants carry out one or more of the selected tasks and submit runs 
to be evaluated. Results are
to be written up and presented at the MediaEval 2010 workshop, which 
will be held the Sunday, 24
October 2010 in Pisa, Italy. ACM Multimedia 2010 starts the next day 
nearby in Firenze.

MediaEval 2010 is sponsored by the PetaMedia Network of Excellence 
dedicated to R&D in the area of
multimedia access and retrieval.
