Query: Intellectual interchanges in the history of the massive online
  open-editing encyclopedia, Wikipedia   Wikipedia is a free Internet encyclopedia with an enormous amount of content.
This encyclopedia is written by volunteers with various backgrounds in a
collective fashion; anyone can access and edit most of the articles. This
open-editing nature may give us prejudice that Wikipedia is an unstable and
unreliable source; yet many studies suggest that Wikipedia is even more
accurate and self-consistent than traditional encyclopedias. Scholars have
attempted to understand such extraordinary credibility, but usually used the
number of edits as the unit of time, without consideration of real time. In
this work, we probe the formation of such collective intelligence through a
systematic analysis using the entire history of 34,534,110 English Wikipedia
articles, between 2001 and 2014. From this massive data set, we observe the
universality of both timewise and lengthwise editing scales, which suggests
that it is essential to consider the real-time dynamics. By considering real
time, we find the existence of distinct growth patterns that are unobserved by
utilizing the number of edits as the unit of time. To account for these
results, we present a mechanistic model that adopts the article editing
dynamics based on both editor-editor and editor-article interactions. The model
successfully generates the key properties of real Wikipedia articles such as
distinct types of articles for the editing patterns characterized by the
interrelationship between the numbers of edits and editors, and the article
size. In addition, the model indicates that infrequently referred articles tend
to grow faster than frequently referred ones, and articles attracting a high
motivation to edit counterintuitively reduce the number of participants. We
suggest that this decay of participants eventually brings inequality among the
editors, which will become more severe with time.
