Abstract:
Deployed video search systems rely on the video uploader to annotate their video with relevant meta-data. If a user gives no search terms or misleading search terms for their video, that video is effectively invisible. The goal of this project is to augment user supplied video search terms with additional terms that are generated directly from the video content. The approach presented in this talk, developed over 12 weeks by a summer intern, had the aim of providing a benchmark upon which to evaluate more sophisticated methods. In essence it relies on nearest-neighbor search performed on a massive scale. The talk will describe our method and the supporting research ecosystem at Google that allowed for the quick turn-around from an idea to a system that could be tested over 10 million videos.
Bio:
Gideon Mann is a Research Scientist at Google New York. He received an Sc.B. in Computer Science from Brown University (1999), and an M.S. (2004) and a Ph.D. (2006) in Computer Science from The Johns Hopkins University. He worked as a post-doctoral researcher at the University of Massachusetts, Amherst from 2005 - 2007 in the IESL lab and is still in active collaboration with this group. His current research interests are semi-supervised learning, information extraction, and large scale machine learning.
