Different from existing work which learns a ranker from positive video examples and hundreds of negative examples, we aim to query web video for events using zero or only a few visual examples. To that end, we propose in this paper a tag-based video retrieval system which propagates tags from a tagged video source to an unlabeled video collection without the need of any training examples. Our algorithm is based on weighted frequency neighbor voting using concept vector similarity. Once tags are propagated to unlabeled video we can rely on off-the-shelf language models to rank these videos by the tag similarity. We study the behavior of our tag-based video event retrieval system by performing three experiments on web videos from the TRECVID multimedia event detection corpus, with zero, one and multiple query examples that beats a recent alternative.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"TagPropagation\" src=\"http:\/\/www.ceessnoek.info\/wp-content\/uploads\/2014\/04\/TagPropagation-e1396517217762.png\" width=\"600\" height=\"228\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The ICMR2014 paper\u00a0Few-Example Video Event Retrieval Using Tag Propagation by Masoud Mazloom, Xirong Li and Cees Snoek is now available.\u00a0An emerging topic in multimedia retrieval is to detect a complex event in video using only a handful of video examples.
