US-police shooting of blacks live, how do social networking sites tube? -Live,
Facebook-IT information
On the way home from rear lamps damaged police stopped by Minnesota, reached for documents, was shot and killed by police. And his girlfriend daimeng·leinuo (Diamond Reynolds) and sat in the back seat of the 4 year old daughter witnessed the whole process, and in France via live Facebook after being shot in the scene. Reynolds said in the video, the police fired four or five shots to Castile. Just 2.5 hours after the broadcast ended, Facebook has removed from its Web site this bloody video.
And just last month, Facebook has been on the site for some in France terror live. In the video, a man who claimed to be a terrorist hijacking a boy hostage. In Facebook before you make the video taken down, it's on the Web for spent 11 hours.
So far this year, with Facebook as the representative of many European and American technology companies have injected areas of live video, and users through the services provided by Facebook and Twitter, but also have the ability to live their lives in real time.
Now, watch news video by Facebook user on Facebook every day to watch the total length has exceeded 100 million hours of video, and Facebook are heavily betting on live video, believes that this new service will lead the user to visit its site more frequently, and allow them to stay for a long time, and this will be further enhanced its ad rates.
In addition to allowing users to upload live spontaneously outside of video, Facebook also signed a number of cooperation partners, paying them for live video.
According to the Wall Street Journal in a report published last month revealed that Facebook currently has with media companies and video content producers signed nearly 140 contracts, valued at more than $ 50 million.
However, the live video on the social media site or a field full of all kinds of unknown factors. Last year, at least 18 involving rape, murder, suicide and all the sex and violence elements of video with live video on the Web is spread.
Facebook's ability to cope with these extreme videos is tested twice in the last week: in Minnesota shooting, live video after officials removed by Facebook, and upload again, and was saved by 1 hour. And then encountered Dallas police shooting, also a witness at the scene through the Facebook Live televised the entire process. As of now, these two videos to Facebook, has been watched by more than 5.6 million times.
Stanford Law School Center for Internet and society privacy officer aibote·gudiya (Albert Gidari) says: "for what can be broadcast live, what can be shared for these two issues, we take them there seems to be no limit. Water can carry a boat, it can also overturn it. ”
Facebook live and other websites in addressing such violence inconsistent response shown by the video issue, also highlights the technology website does not specifically deal with technical and specialized human input, to operate such services have potential risk is so great.
In fact, whether it be Facebook or Twitter, which has been a standard to limit the user to upload their Web sites involving violent video, prevents users from uploading content to those likely to inspire violence or praise violence. But there is one exception, and that is when the videos have news value, their upload process will be everywhere.
In the past, social media sites, review the contents of the main method relies on users to report, subsequently evolved into screening filters one by one through the program or artificial, for the video of the live class, but, it is a bit a banquet. Besides the human review, Facebook does not currently have any live video software has the ability to recognize violence.
Facebook says they will always have a team from a review of the video that was marked by the user. Twitter Periscope video service will randomly pick the Viewer, asking who they were tagged by other users live video needs to be reviewed.
On Friday, Facebook admits they are not able to accurately monitor the ability to broadcast live video. In an official blog, Facebook said:"Facebook live video service is a completely new form, are fast-growing content. Over the last few months, we have learned a lot of things, and will continue to do all we can to continue to improve this new experience. ”
At present, we can already see an improvement is: If a live video that was marked by the user did violate the company's rules, others break it continued power.
However, the live video of the class itself is a difficult challenge to judge, this is a live video once it starts, it is hard to tell with the advance of time, whether it really would happen to violate site rules.
David Thomson, work as a journalist in Paris (David Thomson), said last month in France in the video broadcast, the terrorists made a series of provocative remarks, but the video does not have any display pictures of violence.
Thomson was able to watch this video, because he focused on the Facebook account of who claimed to be a terrorist. On Facebook after the video pulled from the Internet, Thomson made a couple of comments, but not be labeled directly reporting to the Facebook official.
At present, many technology companies are beginning to test a more proactive approach to deal with this type of content. Over the last few months, Facebook has been testing a new feature: once a live video playback reaches a certain amount, or after a viral spread, regardless of whether they have been reported, they will be sent to the review.
Comprehensive control over all challenges before, went first to publish live video services approach also reflects the thinking of Silicon Valley-style: bottom up, others consider it again.
In May this year, right after Facebook launched Facebook Live for months, Florida man, 30 years old live his confrontation with one of the police, the latter court orders, to send him to hospital.
During the 3-hour time, uploaded 9 live video before and after the man, in the video, he continually uses various words to threaten police.
"Have the ability to shoot me! You will witness this death, but even dead, I want to pull back. "Florida man growled in a video, and finally he was diagnosis for medical treatment.
Although the video is filled with disturbing rhetoric, but Facebook has determined the video itself does not violate site rules, and allows them to be stored on the site, didn't even have a warning.
In Minnesota after the live video of the shooting, people immediately realized the value of broadcast violence. Community coalition against police brutality in Minneapolis, President of mixieer·geluosi says: "this real-time live information display promoting the demonstrations. ”
美警察枪杀黑人被直播，社交网站怎么管？ - 网络直播,
Facebook - IT资讯
在回家路上因车尾灯损坏被明尼苏达州警方拦下，伸手取证件时，被警察开枪射杀。而其女友戴蒙·雷诺（Diamond Reynolds）及坐在后座的4岁女儿目睹了全过程，并在卡斯蒂利亚中枪后通过Facebook直播了案发现场。雷诺在视频中表示，警察向Castile开了四五枪。就在直播结束的两个半小时后，Facebook从其网站上撤下了这段血腥的视频。
而就在上个月，Facebook网站上也出过了一段发生在法国的恐怖直播。在视频中，一名声称自己是恐怖分子的男子劫持了一名男孩作为人质。在Facebook将这段视频撤下之前，它在网上整整停留了11个小时。
今年以来，尤以Facebook为代表的众多欧美科技公司都纷纷注资视频直播领域，而用户通过Facebook和Twitter的所提供的服务，也具备了实时直播自己生活的能力。
目前，通过Facebook来观看新闻视频的用户每天在Facebook观看视频的总时长已经超过了1亿小时，而Facebook也重金押注视频直播，认为这项新服务将带领用户更频繁地登陆它的网站，并让他们停留更长的时间，而这将进一步地提升它的广告费率。
除了允许用户自发的上传直播视频之外，Facebook还签约了一系列的合作伙伴，付费让他们进行视频直播。
根据《华尔街日报》在上个月刊发的一篇报道透露，Facebook目前已经同相关传媒公司和视频内容生产商签订了将近140份合同，其总价值超过了5000万美元。
然而，视频直播对社交媒体网站来说其实还是一块充满各种未知因素的领域。在去年，至少有18份涉及强奸、凶杀、自杀等等色情暴力元素的视频以视频直播的方式在网络上被扩散。
而Facebook应对这类极端视频的能力也在上周被测试了两次：在明尼苏达州枪击案中，直播视频在被Facebook官方撤下之后，又被再度上传，并被存留了1个多小时。而在随后的达拉斯警方所遭遇的枪击事件中，也有现场目击者通过Facebook Live直播了整个过程。截至目前，这两段视频在Facebook上的观看量都已超过了560万次。
斯坦福法学院互联网与社会研究中心的隐私保护处主任艾伯特·贾迪亚（Albert Gidari）表示：“对于什么可以被直播、什么直播可以被分享这两个问题来说，我们对它们似乎没有任何的限制。水能载舟，亦能覆舟。”
Facebook及其它直播网站在处理这类暴力视频问题时所表现出的反应不一致，也彰显出在些科技网站这没有专门应对技术和专门人力投入下，去运营这类服务所潜在的风险是无比的巨大。
其实，无论是Facebook还是Twitter，它们都已出台了相应的标准来限制用户向它们的网站上传那些涉及暴力的视频，禁止用户上传那些容易激发暴力或是赞美暴力的内容。但唯有一个例外，那就是当视频具有新闻价值时，它们的上传过程将通行无阻。
在过去，社交媒体网站审查内容的主要方法依赖于用户的举报，随后发展成为通过程序或是人工来逐一甄别筛选，但这对直播类的视频来说，就显得有点派不上用场了。除了人为审查之外，Facebook目前还不具备任何有能力识别出暴力直播视频的软件。
Facebook方面表示，它们内部有一个团队会一直全天候地审查那些被用户标记的视频。而Twitter的Periscope直播服务则会随机地挑选那些观看者，询问他们那些被其他用户标记过的直播视频是否需要被审查。
在上周五，Facebook方面承认自己还不具备能精准监控直播视频的能力。Facebook在一篇官方博客中表示：“Facebook的直播视频服务是一种全新的、正在高速成长当中的内容形式。在过去的几个月里，我们也学习到了许多东西，并将继续尽我们所能得去不断地改进这项新体验。”
目前，我们已经能看到的一项改进是：如果一个被用户标记过的直播视频确实违反了公司的相关规定的话，其他人就有中断它继续进行的权力。
然而，直播类的视频本身就存在一个很难被判别的挑战，那就是一段直播视频一旦开始，我们就很难判断出随着时间的推进，它是否真得会发展至违反网站的规定。
在巴黎从事记者工作的大卫·汤姆森（David Thomson）表示，在上个月发生在法国的那段视频直播中，恐怖分子发表了一系列具有煽动性的言论，但视频表面却没有任何显示暴力内容的图片。
汤姆森之所以能观看到这段视频，是因为他在Facebook上关注过有这名自称是恐怖分子的账号。在Facebook将这段视频从网上撤下之后，汤姆森发了几个评论，但并未将它直接标记举报到Facebook官方。
目前，多家科技公司都开始测试更多更为主动的方法，来处理这类特殊的内容。在过去的几个月里，Facebook一直在测试一项新的功能：一旦一个直播视频的播放量达到了一定数量或是产生了病毒式的传播之后，不管它们是否遭到举报，它们都会被送至审查。
在全面掌控所有挑战之前，就去抢先发布视频直播服务的这一做法也很好地体现了硅谷式的思维：先干了再说，其它再考虑。
在今年五月，就在Facebook上线Facebook Live的数月之后，佛罗里达州的名30岁的男子直播了他同警察的一场对峙，后者应法院指令，要送他进医院就诊。
在长达3个多小时的时间里，该男子前后上传了9段直播视频，在视频中他不断地用各种言语去威胁警察。
“有本事开枪射我啊！你们将见证到有人在此殒命，但即便是死，我也要拉个垫背的。”佛罗里达州的这名男子在一段视频中这样怒吼道，最后他还是被送诊就医了。
尽管这些视频充斥着各种令人不安的威胁言论，但Facebook方面却判定视频本身并不违反网站的相关规定，并允许它们一直被保存在网站上，甚至连个警告都没给。
在明尼苏达州枪击案直播视频出来后，人们立马就意识到了直播暴力事件的价值。明尼阿波利斯市社区反警察暴行联盟的主席米歇尔·格罗斯表示：“这种实时直播信息的展示方式推动了这场示威运动的进行。”
