The following article describes two approaches todetermining the geo-coordinates of the recording place of Flickrvideos based on textual metadata. The systems are tested on theMediaEval 2010 Placing Task evaluation data, which consists of5091 unfiltered test videos and metadata records. The first systemis a data-driven approach that uses a heuristics based on thespatial variance of tags. The second one extends this heuristicsby using semantic technologies, such as extended Wordnet and ageographical gazetteer. The performance peaks at being able to
