TalkMiner: A Search Engine for Online Lecture Video

Abstract

TalkMiner is a search engine for lecture webcasts.
Lecture videos are processed to recover a set of distinct slide images and OCR is used to generate a list of indexable terms from the slides.
On our prototype system, users can search and browse lists of lectures, slides in a specific lecture, and play the lecture video. Over 10,000 lecture videos have been indexed from a variety of sources. A public website now allows users to experiment with the search engine.
