VOA常速英语:AI Software Differentiates Between Extremist Propaganda and News

Millions of videos are uploaded to the internet every day, and London-based ASI Data Science has developed an artificial intelligence algorithm designed to identify those from extremist groups.
每天以百万计的视频上传到互联网，每天有数总部位于伦敦的ASI数据科学公司开发了一种人工智能算法，用于识别来自极端主义团体的视频。
“So we can see two videos here. They look relatively similar to the untrained eye. But one of them is news footage of Daesh, the other is a Daesh propaganda video. The model that we have built is trained to look for a range of subtle signals that these videos are giving off that allow it to distinguish between Daesh propaganda and basically all of the other videos on the internet. So, here, we can see on the left. We have got a video that’s consistently giving a fairly low score. So this one is a news reporting, it’s safe, it can be passed through. On the other hand, the video on the right, here, is throwing off a large range of worrying looking signals.This is high risk. This is indeed-propaganda. And so the models being designed in such a way that platforms can use this as videos are uploaded to filter out the propaganda so that it can be removed before it hits the internet in the first place.”
我们可以在这里看到两个视频，在未经专业培训的人看来它们十分相似。但其中一个是有关伊斯兰国的新闻画面，另一个则是极端主义团体的宣传视频。我们建立的模型经过训练，可以查找这些视频发出的一系列微妙信号，以便区分极端组织的宣传视频和互联网上基本上所有视频。所以，我们可以看到在左边。这个视频的评分一直很低。所以它是一段新闻报道，是安全的，可以通过检验然后上传。另外一边，我的右手边，这个视频显示出了一系列令人担忧的信号，风险很高。它也确实是极端组织的宣传视频。所以，设计它的初衷就是让各大平台能在视频首次上传到互联网之前成功过滤掉极端组织的宣传视频。
That’s important because propaganda videos by Daesh, the arabic acronym for Islamic state are though to help radicalize some extremists.
这很重要，因为达伊什（伊斯兰国的阿拉伯文首字母缩写）的宣传视频正在使极端主义分子更激进化。
“The home office research shows that there’s over a thousand different extremist videos online right now on 400 platforms, so even if Google and Facebook were to solve this overnight, this content would still be accessible through a web browser on, you know, 398 different platforms.”
英国家庭办公室的研究显示，现在网上有超过1000个不同的极端视频出现在400个平台上，所以即使谷歌和Facebook在一夜之间消除了所有极端视频，他们仍然可以通过网络浏览另外398个不同平台的内容。
The British Government is expected to give the software free of charge to those platforms currently hosting extremist videos online. ASI Data Science says, it’s software would make it possible for one person to moderate all the videos uploaded to YouTube or Facebook in a single day.
英国政府预计免费提供这款软件给那些目前在网上能查到极端主义视频的平台。ASI数据科学表示，他们研发的这款软件能让一个人在一天之内检查完所有上传到YouTube或Facebook上的视频。
