在线知识生产网站,如维基百科和Stack Overflow,由一小群贡献者主导。这对知识质量和生产有何影响?在最具生产力的成员中持续存在一些关键贡献者,从总体上考虑,是否提高了知识的质量?本文通过关联贡献不均匀性、精英弹性(粘性)和内容质量的每周价值变化来解决这些问题。目标是检测社会结构变量的变化是否以及如何影响两个具有代表性的在线知识生产网站:Wikipedia和Stack Overflow所产生的知识质量。回归分析表明,在堆栈溢出时,不均匀性和精英粘性对质量都有曲线影响。质量是优化在特定水平的精英粘性和不均匀。同时,在维基百科上,质量随熵的下降呈线性增长,总体而言,在成熟阶段,随着黏性的增加,在一个熵精英黏性之后,达到内容质量的峰值。
Online knowledge production sites, such as Wikipedia and Stack Overflow, are dominated by small groups of contributors. How does this affect knowledge quality and production? Does the persistent presence of some key contributors among the most productive members improve the quality of the knowledge, considered in the aggregate? The paper addresses these issues by correlating week-by-week value changes in contribution unevenness, elite resilience (stickiness), and content quality. The goal is to detect if and how changes in social structural variables may influence the quality of the knowledge produced by two representative online knowledge production sites: Wikipedia and Stack Overflow. Regression analysis shows that on Stack Overflow both unevenness and elite stickiness have a curvilinear effect on quality. Quality is optimized at specific levels of elite stickiness and unevenness. At the same time, on Wikipedia, quality increases linearly with a decline in entropy, overall, and with an increase in stickiness in the maturation phase, after an entropy elite stickiness, quality of content peak is reached.
