Kim coauthors paper on crowd sourced video annotation

Educational researchers have long held that presenting students with clear outlines of the material covered in lectures improves their retention. Recent studies indicate that the same is true of online how-to videos, and in a paper being presented at the Association for Computing Machinery’s Conference on Computer-Supported Cooperative Work and Social Computing in March, researchers at MIT and Harvard University describe a new system that recruits viewers to create high-level conceptual outlines.

‘That addresses one of the fundamental problems with videos,’ says Juho Kim, an MIT graduate student in electrical engineering and computer science and one of the paper’s co-authors. “It’s really hard to find the exact spots that you want to watch. You end up scrubbing on the timeline carefully and looking at thumbnails. And with educational videos, especially, it’s really hard, because it’s not that visually dynamic.
