Cooperation and quality in Wikipedia
Abstract The rise of the Internet has enabled collaThe rise of the Internet has enabled collaboration and cooperation on anunprecedentedly large scale. The online encyclopedia Wikipedia, which presently comprises 7.2 million articles created by 7.04 million distinct editors, provides a consummate example. We examined all 50 million edits made tothe 1.5 million English-language Wikipedia articles and found that the high-quality articles are distinguished by a marked increase in number of edits, number of editors, and intensity of cooperative behavior, as compared to other articles of similar visibility and age. This is significant because in other domains, fruitful cooperation has proven to be difficult to sustain as the size of the collaboration increases. Furthermore, in spite of the vagaries of human behavior, we show that Wikipedia articles accrete edits according to a simple stochastic mechanism in which edits beget edits. Topics of high interest or relevance are thus naturally brought to the forefront of quality.rally brought to the forefront of quality.

Conclusion We have shown that the high-quality articlWe have shown that the high-quality articles in Wikipedia are distinguished from the rest by a larger number of edits and distinct editors, having carefully controlled for article visibility, popularity, and age. Furthermore, we demonstrated more intense patterns of cooperation in the high-quality articles than in other articles. These findings are in contrast to observations of cooperative efforts in other domains where result quality does not necessarily increase with the number of collaborators. While we did not explore the question of how Wikipedia succeeds where other large collaborative ventures fail, possible reasons include the efficiency of the wiki interface, the Wikipedia community’s strong emphasis on coordination and organization [32], and details of the processes and policies used to facilitate cooperation [23]. Additionally, we have have shown that althoughWikipedia is a complex system in which of millions of individually unpredictable editors collaborate in an unscheduled and virtually uncontrolled fashion, article growth follows a very simple overall pattern on average. This pattern implies that a small number of articles, corresponding to topics of high relevance or visibility, accrete a disproportionately large number of edits, while the vast majority of articles experience far less activity. Subjects of particular importance or popularity are thus naturally brought to the forefront of quality, validating Wikipedia as a successful collaborative effort.edia as a successful collaborative effort.
