Abstract : This paper describes our approach and results in the hyperlinking sub-task at MediaEval 2013. A two step method is implemented where the fi rst step consists in establishing a shortlist of relevant videos. In the second step, a target segment is selected from each video in the shortlist. We focus on target selection comparing two distinct strategies. The fi rst one exploits a bipartite graph relating utterances and words to find the most relevant utterances from which segments are derived. The second one uses explicit topic segmentation, whether hierarchical or not, to select the target segments.
