作为全世界最成功的短视频软件之一，TikTok（抖音海外版）通过人工智能推荐算法等技术，根据用户喜好、软件使用习惯等因素进行内容推荐，让不少人沉迷其中。TikTok究竟是如何“读心”的？对待这样的互联网平台，我们应该怎样正确对待，才不至于使自己局限于某一特定领域而不能自拔，精疲力竭呢？

How TikTok Reads Your Mind

Tiktok是这样读懂了你的想法

There are four main goals for TikTok's algorithm: 用户价值, 用户价值 (长期), 作者价值, and 平台价值, which the company translates as "user value," "long-term user value," "creator value," and "platform value."

TikTok的算法有四个主要目标。这四个词翻译为英文后，意思分别是：“用户价值”、“长期用户价值”、“创作者价值”和“平台价值”。

That set of goals is drawn from a frank and revealing document for company employees that offers new details of how the most successful video app in the world has built such an entertaining — some would say addictive — product.

这组关于目标的词，来自该公司一份内部文件。这份直截了当的文件披露了大量信息，也提供了一些新细节：这个世界上最成功的视频应用程序，何以成为一款如此乐趣十足，甚至可以说是令人上瘾的产品。

The document, headed "TikTok Algo 101," was produced by TikTok's engineering team in Beijing.

这份文件名为《TikTok算法101》，由该公司位于北京的工程师团队编撰。

The document explains frankly that in the pursuit of the company's "ultimate goal" of adding daily active users, it has chosen to optimize for two closely related metrics in the stream of videos it serves: "retention" — that is, whether a user comes back — and "time spent." The app wants to keep you there as long as possible. The experience is sometimes described as an addiction.

文件直言不讳地写道，该公司追求的“终极目标”是增加日活用户。为此，针对提供给用户的视频内容流，TikTok选择优化的是两个密切相关的指标：“留存率”和“访问时长”。其中，留存率指的是用户是否会再次使用这个软件。这款应用希望留住你，留的时间越长越好。有时，这种体验会被描述为上瘾。

The document says watch time isn't the only factor TikTok considers. The document offers a rough equation for how videos are scored, in which a prediction driven by machine learning and actual user behavior are summed up for each of three bits of data: likes, comments and playtime, as well as an indication that the video has been played.

这份文件称，观看时长并不是TikTok考虑的唯一因素。文件中提供了一个粗略的视频评分公式。该公式综合考虑了两个因素：基于机器学习的预测，和用户的实际行为。其计算体现在三类数据中：点赞数、评论量和播放时长。同时，也有参数判定一条视频是否被播放过。

"The recommender system gives scores to all the videos based on this equation, and returns to users videos with the highest scores," the document says.

这份文件写道：“推荐系统会根据这个公式给所有视频打分，并将得分最高的视频反馈给用户。”
