Abstract : We describe our approach and results towards the Hyperlinking sub-task at MediaEval 2012. We approached this as an Information Retrieval task and used re-ranking strategies for finding relevant videos. A three-step approach was then applied on results to extract the most relevant part of the video regarding the query content. Our results show that re-ranking strategies and integration of metadata information both improve the system performance.
