TalkMiner is “Google for online educational videos”. It continuously crawls various video sources to create a comprehensive search index of online educational videos as they are published by top institutions like MIT, Stanford, UC Berkeley, and TED.
Palo Alto, CA (PRWEB) April 20, 2011
FX Palo Alto Laboratory (FXPAL), has launched TalkMiner (http://www.talkminer.com), an online video search service that empowers students and professionals to more quickly locate educational videos—and topics within videos—from the vast and rapidly expanding web of online video content. With the explosion of open, high-quality educational videos being published by leading institutions such as MIT, Stanford, UC Berkeley, and TED, people need to search within videos, instead of locating videos based only on titles and descriptions, and then manually hunting through the videos to find what they are seeking.
TalkMiner is a bit like “Google for online educational videos” in that it continuously crawls various video sources to create a comprehensive search index of online educational videos as they are published by top institutions. TalkMiner currently indexes over 15,000 videos, in both English and Japanese, and is increasing its collection daily.
TalkMiner employs advanced multimedia analysis techniques to create a consistent and usable interface for searching and skimming lecture videos from a variety of sources based on presentation content found within the videos, such as presentation slides. In contrast, services like YouTube and iTunes only allow users to search based on video titles and descriptions.
When a user issues a keyword search, TalkMiner produces a ranked list of relevant videos based on titles, descriptions, and text found within the videos themselves, such as text on presentation slides or a whiteboard. When the user selects a video to learn more, TalkMiner presents a thumbnail overview of all the slides extracted from the lecture, with visual cues indicating which slides contain the user’s search terms. The user can then dramatically save time by clicking on specific slides to instantly playback segments within the video corresponding to the user’s interests.
According to Larry Rowe, FXPAL’s president and the founding director of the Berkeley Multimedia Research Center, “Studies of the Berkeley Webcasting System taught us that students primarily want to review selected material. In one class, for over 50% of the lectures, students watched less than 10 minutes from a 50-minute lecture, and they watched the entire lecture only 10% of the time. Consequently, for effective use of online lecture videos, effective search is a big issue.”
The goal of TalkMiner is to organize the world’s open online educational videos and make them more usable. FXPAL welcomes interested students, professionals, and others to try TalkMiner for free at http://www.talkminer.com.
