The free encyclopedia that anyone can dispute : An analysis of the micro-structural dynamics of positive and negative relations in the production of contentious Wikipedia articles

Abstract

We consider two rival hypotheses on the emergence of organization in open production communities. According to the first (“reputation hypothesis”), patterns of agreement and disagreement among participants in open production communities are explained by differences in individual reputation for quality of contribution. The reputation hypothesis predicts that participants will tend to agree with more reputable others and disagree with less reputable others thus contributing to establish a stable open production community. According to the second hypothesis (“balance hypothesis”), patterns of agreement and disagreement are explained by membership in sub-communities of “friends” and “enemies.” The balance hypothesis predicts that participants in open production communities will agree mainly with friends and disagree mainly with enemies, regardless of considerations about reputation for the quality of their contributions. In this paper, we examine which one of these hypotheses is more consistent with patterns of positive and negative interaction events observed during the production of the complete set of 1,206 English-language Wikipedia articles officially considered controversial. We specify and estimate new models for signed and weighted relational event networks predicting the probability that a user deletes the contributions of another user – thus expressing personal disagreement – and/or protects the contributions of another user against deletion from third parties – thus expressing personal agreement. In an analysis of positive and negative interaction among Wikipedia contributors consisting of more than 60 million observations, we find strong support for the balance hypothesis and for the predictions of the reputation hypothesis that are more consistent with alter-centric interpretations of social status as conferred by alters through observable acts of deference.
