论文摘要
徽章是在线互动网站的特有，从问答（问答）网站乘坐共享，作为奖励参与者的贡献的系统。本文研究徽章设计如何影响人们的贡献和行为。过去的工作表明，在获得徽章之前，徽章“转向”人们的行为大大增加了贡献的数量，并立即减少其贡献，从而恢复了基线贡献水平。相比之下，我们发现转向效果取决于用户贡献的速率和强度模型的用户类型。我们使用这些措施来区分不同的用户活动组，包括尽管对网站的重要贡献者，但不受徽章系统影响的用户。我们提供了一个预测模型，说明用户如何在系统中的一生中更改其活动组。我们在三种不同的Q \＆A网站与数十万用户的三种不同的Q \＆A网站进行经验证明了我们的方法，以进行两种类型的活动（在帖子上进行编辑和投票）。
Badges are endemic to online interaction sites, from Question and Answer (Q&A) websites to ride sharing, as systems for rewarding participants for their contributions. This paper studies how badge design affects people's contributions and behavior over time. Past work has shown that badges "steer" people's behavior toward substantially increasing the amount of contributions before obtaining the badge, and immediately decreasing their contributions thereafter, returning to their baseline contribution levels. In contrast, we find that the steering effect depends on the type of user, as modeled by the rate and intensity of the user's contributions. We use these measures to distinguish between different groups of user activity, including users who are not affected by the badge system despite being significant contributors to the site. We provide a predictive model of how users change their activity group over the course of their lifetime in the system. We demonstrate our approach empirically in three different Q\&A sites on Stack Exchange with hundreds of thousands of users, for two types of activities (editing and voting on posts).
