我们调查了一个分布式社交互动的范例的计算结构:开源维基百科社区的计算结构。我们检查其合作行为的统计性质,并进行模型选择,以确定系统的这一方面是否可以用有限状态过程来描述,或者引用有效无界资源是否允许进行更简明的描述。我们发现,在大多数编辑次数最多的页面中,有强有力的证据支持集体国家模式,在这种模式下,“恢复”操作的概率随着自上次恢复以来出现的非恢复操作数量的平方根而下降。我们提供的证据表明,这种社交计数器的出现是由集体互动效应驱动的,而不是由个人用户的属性驱动的。
We investigate the computational structure of a paradigmatic example of distributed social interaction: that of the open-source Wikipedia community. We examine the statistical properties of its cooperative behavior, and perform model selection to determine whether this aspect of the system can be described by a finite-state process, or whether reference to an effectively unbounded resource allows for a more parsimonious description. We find strong evidence, in a majority of the most-edited pages, in favor of a collective-state model, where the probability of a “revert” action declines as the square root of the number of non-revert actions seen since the last revert. We provide evidence that the emergence of this social counter is driven by collective interaction effects, rather than properties of individual users.
