多样化战略在可持续知识生产中的作用
The Role of Diverse Strategies in Sustainable Knowledge Production
摘要：
在线社区作为大规模人类合作的平台正变得越来越重要。这些社区允许用户寻求和分享专业技能，以协作解决问题。为了研究用户如何合作完成大量的知识生产任务，我们分析了StackExchange，世界上最大的问答系统之一。我们构建注意力网络模型的StackExchange系统中的110个社区的增长和量化个人的回答策略使用的注意力网络的链接动态。我们确定了两种类型的用户采取不同的策略。一种策略（A型）旨在通过执行简单任务来执行维护，而另一种策略（B型）旨在将时间投入到具有挑战性的任务中。我们发现，A类用户的数量需要是B类用户的两倍，才能实现社区的可持续增长。
英文摘要：
Online communities are becoming increasingly important as platforms for large-scale human cooperation. These communities allow users seeking and sharing professional skills to solve problems collaboratively. To investigate how users cooperate to complete a large number of knowledge-producing tasks, we analyze StackExchange, one of the largest question and answer systems in the world. We construct attention networks to model the growth of 110 communities in the StackExchange system and quantify individual answering strategies using the linking dynamics of attention networks. We identify two types of users taking different strategies. One strategy (type A) aims at performing maintenance by doing simple tasks, while the other strategy (type B) aims investing time in doing challenging tasks. We find that the number of type A needs to be twice as big as type B users for a sustainable growth of communities.
