User Generated Content or UGC is the stuff that users upload to blogs, social networks, discussions, evaluations of products—it's all that text, photos, images, audio, slideshows, etc. that people can upload online. It sounds like a good idea to let users upload to pages on a site or make comments, but this can be a big problem. What's uploaded might be not be appropriate, and/or it may be racist, pornographic, or bullying. It's difficult for sponsors of sites to keep up with what's posted, for the amount of content uploaded multiplies each day. Social networking sites and commercial sites often hire an army of monitors to oversee user-generated content. Some sites say they look at every photo that's uploaded. Think of the number of people hours this must take. Realizing the problems involved when trying to oversee UGC, Keibi (pronounced Kay-bee) Technologies has developed a system that can evaluate uploaded content. Keibi pulls out what it considers possible problems and gets them ready for human monitors to check. To do this, the company has developed a number of ways to check audio, graphics, video and text and how these might relate to one another. It can check to see if the person uploading has violated the site's Terms of Use in the past. Video is evaluated by breaking it down into frames and targeting the five frames with the most unfavorable score. For text, Keibi uses a semantic filter to look at word relationships. After Keibi does its work, about 20% of the content is then sent on to monitors who do the final evaluation. Results from the monitors are put back into the system to help Keibi continue to improve its evaluations. —Sounds like something that's needed to keep UGC in line with standards or Terms of Use of the organizations that encourage uploading of content.
