Facebook調整算法 着手應對消息流垃圾廣告

Websites that harbour "disruptive, shocking or malicious" adverts will appear less frequently on user's news feeds, Facebook has said.

Facebook於日前表示，用戶新的的消息流中“破壞性的、駭人聽聞的、惡意的”網站廣告數將會有所減少。

The social network is tweaking the algorithm that picks posts for feeds to do a better job of spotting "low quality" web pages. Instead, the algorithm will seek out more informative posts.

該社交網站正在調整爲消息流挑選帖子的算法，以更好的檢測出“劣質”網頁。取而代之的是，該算法將找出更有“營養的”帖子。

It said the change was part of broader work it was doing to make Facebook less profitable for spammers.

Facebook方面表示，這一改進是意在讓垃圾郵件發送者無法從Facebook中賺錢的項目的一部分。

The change was aimed at sites that contained "little substantive content" and were set up only to profit from users' attention, it said.

Facebook稱，此次調整的目標是隻包含“少量實質性內容”和只爲從用戶的關注中牟利的網站。

Users had told it they were "disappointed" when they clicked on links that seemed to point to a news site but instead put them on a page built largely around adverts, Facebook said.

Facebook方面表示，有用戶反饋，當點開一個看上去像新聞網頁的鏈接、卻進了一個有很多廣告的頁面時，他們很“失望”。

And these included pages with intrusive pop-up or interstitial ads, or that used pornographic pictures for dating sites or shocking images for treatments that purported to tackle many different ailments.

這些網站有煩人的彈窗或插播廣告，或使用色情圖片爲相親網站配圖，或用誇張的圖片展示解決各種疾病的療法。

Facebook said its analysis of hundreds of thousands of web pages helped it to identify those run by spammers.

Facebook指出，他們對成千上萬網頁的分析，會幫助他們識別這些由垃圾郵件發送者運營的網站。

The updated algorithm would be rolled out across its many territories over the next few months.

接下來的幾個月，升級的算法將陸續登錄各個運營區。
