Invasion biology and the success of social collaboration networks, with application to wikipedia Invasion biology
Social collaboration networks
Stochastic population theory
Wikipedia
Israel Journal of Ecology and Evolution English 2013 We adapt methods from the stochastic theory of invasions - for which a key question is whether a propagule will grow to an established population or fail - To show how monitoring early participation in a social collaboration network allows prediction of success. Social collaboration networks have become ubiquitous and can now be found in widely diverse situations. However, there are currently no methods to predict whether a social collaboration network will succeed or not, where success is defined as growing to a specified number of active participants before falling to zero active participants. We illustrate a suitable methodology with Wikipedia. In general, wikis are web-based software that allows collaborative efforts in which all viewers of a page can edit its contents online, thus encouraging cooperative efforts on text and hypertext. The English language Wikipedia is one of the most spectacular successes, but not all wikis succeed and there have been some major failures. Using these new methods, we derive detailed predictions for the English language Wikipedia and in summary for more than 250 other language Wikipedias. We thus show how ideas from population biology can inform aspects of technology in new and insightful ways. 0 0
So you know you're getting the best possible information: A tool that increases wikipedia credibility Credibility
Wikidashboard
Wikipedia
Conference on Human Factors in Computing Systems - Proceedings English 2009 An experiment was conducted to study how credibility judgments about Wikipedia are affected by providing users with an interactive visualization (WikiDashboard) of article and author editing history. Overall, users who self-reported higher use of Internet information and higher rates of Wikipedia usage tended to produce lower credibility judgments about Wikipedia articles and authors. However, use of WikiDashboard significantly increased article and author credibility judgments, with effect sizes larger than any other measured effects of background media usage and attitudes on Wikiepedia credibility. The results suggest that increased exposure to the editing/authoring histories of Wikipedia increases credibility judgments. Copyright 2009 ACM. 0 0

The singularity is not near: slowing growth of Wikipedia Growth

Population

Wikipedia
WikiSym English 2009 Prior research on Wikipedia has characterized the growth in content and editors as being fundamentally exponential in nature, extrapolating current trends into the future. We show that recent editing activity suggests that Wikipedia growth has slowed, and perhaps plateaued, indicating that it may have come against its limits to growth. We measure growth, population shifts, and patterns of editor and administrator activities, contrasting these against past results where possible. Both the rate of page growth and editor growth has declined. As growth has declined, there are indicators of increased coordination and overhead costs, exclusion of newcomers, and resistance to new edits. We discuss some possible explanations for these new developments in Wikipedia including decreased opportunities for sharing existing knowledge and increased bureaucratic stress on the socio-technical system itself. 0 13
Augmented Social Cognition AAAI Spring Symposium - Technical Report English 2008 Research in Augmented Social Cognition is aimed at enhancing the ability of a group of people to remember, think, and reason; to augment their speed and capacity to acquire, produce, communicate, and use knowledge; and to advance collective and individual intelligence in socially mediated information environments. In this paper, we describe the emergence of this research endeavor, and summarize some results from the research. In particular, we have found that (1) analyses of conflicts and coordination in Wikipedia have shown us the scientific need to understand social sensemaking environments; and (2) information theoretic analyses of social tagging behavior in del.icio.us shows the need to understand human vocabulary systems. 0 0
