The Search and Hyperlinking Task at MediaEval 2013

We describe the runs for our participation in the Search sub-task of the Search and Hyperlinking Task at MediaEval 2013. Our experiments investigate the aect of using information about speech segment boundaries and pauses on the effectiveness of retrieving jump-in points within the retrieved segments. We segment all three available types of transcripts (automatic ones provided by LIMSI/Vocapia and LIUM, and manual subtitles provided by BBC) into fixed-length time units, and present the resulting runs using the original segment starts and using the potential jump-in points. Our method for adjustment of the jump-in points achieves higher scores for all LIMSI/Vocapia, LIUM, and subtitles based runs.
