| dc.description.abstract | This paper describes our Georeferencing approaches, experiments, and results at the MediaEval 2011 Placing Task evaluation. The task consists of predicting the most probable geographical coordinates of Flickr videos. Our approaches used only Flickr users textual annotations and tagsets to predict. We used three approaches for this task: 1) a Geographical Knowledge approach, 2) an Information Retrieval based approach with Re-Ranking, and 3) a combination of both (GeoFusion). The GeoFusion approach achieved the best results within the margin of errors from 10km to 10000km. |
