Time-based segmentation and use of jump-in points in DCU search runs at the search and hyperlinking task at MediaEval 2013.
In: MediaEval 2013 workshop, 18-19 Oct 2013, Barcelona, Spain.
Abstract
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.
