一条推文的半衰期

The Half-Life of a Tweet

Juergen Pfeffer, Daniel Matter, Anahit Sargsyan

AI总结:

通过分析 Twitter 新增的 impression_count 歉量,发现推文展示次数在发布后 72 秒达峰,24 小时后95%推文停止传播,中位半衰期约 80 分钟。

摘要:

Twitter 已开始分享一个 impression_count 变量,作为通过 Twitter API 收集的每条推文可用公共指标的一部分。借助在数据收集时关于特定推文向 Twitter 用户展示的频率信息,我们可以通过随时间重复测量度其其展示次数来了解推文传播过程的重要见解。我们的初步分析表明,平均每秒展示次数的峰值出现在推文发送后 72 秒,且 24 小时后,约 95% 的推文已无法观察到相关的展示次数。最后,我们估计推文的中位半衰期(即所有展示次数中一半产生所需时间)约为 80 分钟。

英文摘要:

Twitter has started to share an impression_count variable as part of the available public metrics for every Tweet collected with Twitter's APIs. With the information about how often a particular Tweet has been shown to Twitter users at the time of data collection, we can learn important insights about the dissemination process of a Tweet by measuring its impression count repeatedly over time. With our preliminary analysis, we can show that on average the peak of impressions per second is 72 seconds after a Tweet was sent and that after 24 hours, no relevant number of impressions can be observed for ~95% of all Tweets. Finally, we estimate that the median half-life of a Tweet, i.e. the time it takes before half of all impressions are created, is about 80 minutes.
