University of Tokyo Adds Video Search From Fuji Xerox to OpenCourseWare Material

Being able to keyword search audio and video is nothing new. However, with the rapidly increasing amount of new video being created plus the digitization of film/video expect to see it become increasingly popular. At the bottom of this post a couple of examples of video search you can use today.

Now, some video search news from Japan. What you’ll read about is not keyword video search (search every word spoken) but is another way to make video more discoverable.

From Fuji Xerox:

To enhance video searching function for the online lectures of the University of Tokyo, Fuji Xerox Co., has offered TalkMiner its video indexing technology, for UTokyo OpenCourseWare developed and managed by the university.

TalkMiner analyzes videos online to identify specific presentation slide images and builds a search index from words on those slides, thereby enabling searches of videos without any metadata. It allows users to search specific scenes within lecture videos that contain key words by simply entering them and clicking the search button.

UTokyo OCW users can thereby view desired scenes of desired lecture videos by easily searching them from the numerous lectures registered on the system.


More than 1,200 lecture videos and course materials given by major professors of the university are currently available to the public. With such vast number of lectures offered, and each lecture being as long as 90 minutes, implementing an efficient search method for users to find lectures they are interested to see was a challenge.
