In this paper, we describe our approach as part of the Me-diaEval 2014 Placing Task evaluation. We first identify tags that are most indicative of geographic location by calculat-ing the spatial-aware weighting for all tags in the training set. These weighting are applied to a language model-based retrieval framework. To address the geo-tagging problem, we find the most similar training item and propagate its lo-cation to the test item. Base on last year’s experience, we further improve the accuracy by utilizing the geo-location correlation of images/videos uploaded by the same user. 1.
