臉書證實存在基於地理位置的好友推薦功能

If that guy who popped up in your Facebook "people you may know" section looks vaguely familiar, it may be because you've recently crossed paths.

如果你在Facebook上的“你可能認識的人”板塊中看到某些人似乎不太熟悉，那麼這很可能是因爲你們最近到過同樣的地方。

The section is usually a trove of high school acquaintances and a random assortment of colleagues with whom you have mutual friends, but Facebook also suggests friends with whom your common link may be unclear.

這個板塊通常會推薦一些高中熟人或者隨機找到的有共同好友的人，但是Facebook也能推薦聯繫並不清晰的人。

It turns out what two people may have in common is a shared GPS data point on their phones.

事實證明，在手機上共享過同樣GPS信息的兩個人可能存在共同點。

Fusion first reported the story after a parent who attended a gathering for suicidal teens said Facebook suggested he friend another parent who attended -- despite having never shared any information with each other.

一位參加過防青少年自殺聚會的家長結合以上報道表示，Facebook給他推薦了一位也參加過這次活動的家長，但是他們之間沒有共享過信息。

Facebook did not immediately respond to ABC News' request for comment. However, a company representative told Fusion that location is just one factor in the algorithm the company uses to populate the "people you may know" section and that the two parents must have also had something else in common.

Facebook沒有馬上對ABC新聞就此事作出解釋的請求做出迴應。但是，公司的一名代表表示，Facebook上共享位置只是“你可能認識的人”模塊算法中的一方面因素，兩位家長一定還有其他的共同點。

While the super-smart algorithm may come in handy for networking with people you met at a party, you don't have to use it. Android users can visit their app manager to open Facebook permissions. From there, toggle location to "off."

雖然這一超智能算法可以用在與參加過同樣聚會的人聯繫，但並不是非得使用它。安卓用戶可以進入應用程序管理器，找到Facebook的權限設置，可以將開關狀態設置爲關閉。

People using an iPhone can turn off location services by going to settings, privacy, location services. Scroll down to Facebook and choose "Never." It's also a great time to evaluate the location settings on your other apps.

使用蘋果手機的人可通過設置-隱私-定位，然後向下滾動屏幕找到Facebook，選擇“從不”來關閉定位服務。同時也可以考慮更改其他app在手機上的定位權限設置。
