Searching video content
A recent article in the NY TImes that says speech recognition is the coming thing in searching videos has triggered some rebuttal from search expert Danny Sullivan. He says:
“Millions of Videos, and Now a Way to Search Inside Them” from the New York Times is a big giant love story to video search firm Blinkx, suggesting that the idea of finding video content will take a leap through new idea of speech recognition. In reality, it’s not a new idea. It’s been in practice for years. And despite those years, it has failed to transform how we search for video on the web. That’s because speech recognition video search is overrated, especially given the true challenge video search faces — just getting the content centralized in the first place.
Search engines cannot really “see” video to understand what it is about any more than they can see images. Instead, to really understand what images or videos are about, they tend to look at metadata — text about the video that is either embedded within the video file or surrounding where the video is placed on a page.
He then goes on to talk about metadata and surveys the history of video search. He concludes:
Overall, I’m sure speech recognition will eventually find its place in video search. Plus let’s skip the hype. It hasn’t been a crucial piece of technology for years, and it’s hardly the next challenge video search faces. The real challenge is figuring out how to work with content owners.
