推特上究竟有多少机器人账号？

Next, details about Elon Musk's potential purchase of Twitter which he agreed to buy for $44 billion back in April.

接下来是关于埃隆·马斯克可能收购推特的细节，他在4月份同意以440亿美元收购推特。

Within a couple weeks, though, Musk was like hold up, and he tried to back away from the deal, accusing Twitter of having too many bots and lying about the number of fake accounts on the platform.

然而，在几周内，马斯克好像在拖延交易，他试图退出这笔交易，指责推特拥有太多机器人，指责推特对平台的虚假账户数量撒谎。

Let's hear more details from Claire Duffy, a cnn business writer covering the business of big tech.

让我们来听听cnn报道大型科技业务的商业撰稿人克莱尔·达菲带来的更多细节。

She'll also dive into a new tool from Twitter that helps the platform determine what's a bot and what's not.

她将会研究推特的一款新工具，该工具能帮助平台确定什么是机器人，什么不是机器人。

In April, Elon Musk agreed to buy Twitter for $44 billion. But within a couple of weeks, he started to get cold feet.

今年4月，埃隆·马斯克同意以440亿美元收购推特。但几周后，他开始临阵退缩。

He accused Twitter of having too many bots and of lying about the number of bots on its platform.

他指责推特有太多机器人，指责推特对平台的虚假账户数量撒谎。

One of the tools that both experts and Elon Musk have used to better understand the prevalence of bots on Twitter's platform is called bottom meter.

多位专家和埃隆·马斯克为了更好地了解机器人在推特平台上的盛行程度，使用了一款名为底层计量器(bottom meter)的工具。

To test out how it works, we can look at my Twitter account and see how it rates me.

为了测试这个工具是如何工作的，我们可以查看我的推特账户，看看它是如何给我评级的。

The bottom meter score is from zero to five.

底层计量器的分数是从0到5。

The zero being most likely to be a human account and five being most likely to be a bot account.

0最有可能是人类账户，5最有可能是机器人账户。

As you can see, the tool rated my account is 0.5 out of 5. So most likely to be a human.

正如你所看到的，这个工具给我的账户评级为0.5分(满分5分)。所以我最有可能是人类账户。

Another cool thing about this tool is if you go into this details section, you can see tweets by time of day and day of the week.

关于这个工具的另一个很酷的事情是，如果你点进这个细节部分，你可以看到每天每时发布的推文，也可以看到每周每日发布的推文。

Now, with a bot account, you might see that the account is tweeting all through the night because it's managed by software and it doesn't need a human to get up and tweet late at night.

现在，如果有一个机器人账户，你可能会看到这个账户整晚都在发推特，因为这个账户是由软件管理的，不需要人类在深夜起床后发推特。

You might also see that they send the same number of tweets every single day of the week which a human just typically wouldn't do.

你可能还会看到，机器人账户每周每天都会发送相同数量的推文，这是人类通常不会做的。

It's important to know that the tool doesn't actually prove whether an account is a bot or not.

重要的是要知道，该工具实际上并不能证明一个账户是不是机器人。

What it does is it looks at the behavior of an account and decides whether it looks more like a human account or something that's automated something that's managed by software.

该工具所做的是观察账户的行为，决定它是看起来更像一个人类账户，还是由软件管理的自动化账户。

We won't know how many bots there are on Twitter.

我们不知道推特上有多少机器人。

I don't know if we'll ever know how many bots there are on Twitter.

我不知道我们是否能辨认出推特上有多少机器人账户。

There's human at one -- on one side of bot, and another side, but many, many accounts on Twitter are run by some combination of humans and bots.

一方面，这些账户要么由人类运营，要么由机器人运营，另一方面，推特上的很多账户都是由人类和机器人联合运营的。

There are also some good bot accounts, automated accounts that help spread news or information about events in the world.

还存在一些很好的机器人账户，这些自动账户会帮助传播有关世界性事件的新闻或信息。

We can take a look at this account Earthquake Bot, which tweets about earthquakes that are happening all around the world to warn people when they've happened.

我们可以看看这个账号“地震机器人”，该账号在推特上发布世界各地正在发生的地震，目的是在地震发生时向人们发出警报。

Bottom meter rates this account as a 4.1 out of 5, most likely to be run by automated software.

底层计量器为这个账户打了4.1分(满分5分)，表明这个账号最有可能是由自动化软件运行的。

And the account does say in its description that it's a bot. It's run by a computer.

该账户在其描述中确实说它是一个机器人。它是由计算机运行的。

Twitter does allow these good bots.

推特确实允许这些好的机器人存在。

It even has a label where they can transparently identify themselves to viewers who might not otherwise know that they were run by a computer.

该账户甚至有一个标签，可以向观众清楚地表明自己的身份，否则观众可能辨别不出他们是由计算机运行的。

Now, of course, there are the bad bots that you've probably seen if you're on Twitter.

当然，如果你在推特上，你可能会看到一些不好的机器人。

The bots that might be trying to get you to buy cryptocurrency or that might be impersonating another real human account.

这些机器人可能会试图让你购买加密货币，或者可能会冒充另一个真正的人类账户。

Elon Musk for one would say that these bots can detract from the user experience and could take away from the long-term value of Twitter.

埃隆·马斯克会说，这些机器人可能会削弱用户体验，并可能会剥夺推特的长期价值。
