KB Video Retrieval at TRECVID 2011
David Etter · TRECVID · 2011
This paper describes KB Video Retrieval's participation in TRECVID 2011. We submitted 4 runs in the automatic Known-Item Search (KIS) task. Our KIS system uses a base text only search for runs KBVR_1_KIS2011 and KBVR_2_KIS2011. Runs KBVR_3_KIS2011 and KBVR_4_KIS2011 extend the text search with pseudo-relevance feedback and semantic concept re-ranking.
