Assessing the value of cooperation in Wikipedia

  title={Assessing the value of cooperation in Wikipedia},
  author={Dennis M. Wilkinson and Bernardo A. Huberman},
  journal={First Monday},
Since its inception six years ago, the online encyclopedia Wikipedia has accumulated 6.40 million articles and 250 million edits, contributed in a predominantly undirected and haphazard fashion by 5.77 million unvetted volunteers. Despite the apparent lack of order, the 50 million edits by 4.8 million contributors to the 1.5 million articles in the English–language Wikipedia follow strong certain overall regularities. We show that the accretion of edits to an article is described by a simple…

Information Uniqueness in Wikipedia Articles
A method is described that captures the information duplication across the article contents in an attempt to infer the amount of distinct information every article communicates, based on the intuition that an article offering unique information about its subject is of better quality compared to an article that discusses issues already addressed in several other articles.
Is Wikipedia Inefficient? Modelling Effort and Participation in Wikipedia
This paper compares the efficiency of Wikipedia projects in different languages and at different states of development to examine the decreased ability of Wikipedia to recruit editors and in to harness the effort of contributors.
Reader preferences and behavior on Wikipedia
It is shown that the most read articles do not necessarily correspond to those frequently edited, suggesting some degree of non-alignment between user reading preferences and author editing preferences.
Statistical Measure of the Effectiveness of the Open Editing Model of Wikipedia
The results suggest that the process underlying Wikipedia can be used for producing high–quality content, but also suggest the viability of collaborative knowledge repositories that impose high barriers to user participation for the purpose of filtering poor quality contributions from the onset.
Identifying Polarized Wikipedia Articles
This chapter proposes the exploitation of a novel indicator for the Wikipedia articles’ quality, namely information credibility, and describes a method that captures the polarized information across the article contents in an attempt to infer the amount of credible (i.e., objective) information every article communicates.
Review-Based Ranking of Wikipedia Articles
The results show that the review-based ranking algorithm which combines the extent of review and text-relevancy outperforms the rest; it is more accurate and less computationally expensive compared to PageRank-based rankings.
Good Articles ?-How Wikis Work
Wikis are websites to develop content collaboratively. The question arises to what extent the reputation of participants influences the quality of wiki sites. We analyze the impact of author
A Model for Information Growth in Collective Wisdom Processes
This work proposes a model for information growth which relies on two main observations: as an article’s quality improves, it attracts visitors at a faster rate (a rich-get-richer phenomenon) and the chances that a new visitor will improve the article drops (there is only so much that can be said about a particular topic).
Struggle for Life in the Wikisphere
This work underline the intertwining of population and content dynamics and emphasize the existence of different periods of development of a wiki-based community, from bootstrapping by founders with a pre-established set of rules, to more stable regimes where constant enrollment and training of new users balances out the occasional departure of more advanced users.
Statistical measure of quality in Wikipedia
This study model the evolution of content quality in Wikipedia articles in order to estimate the fraction of time during which articles retain high-quality status and assess the quality of Wikipedia's featured and non-featured articles.


Measuring Wikipedia
A first overview and outlook on Wikipedia research is given because Wikipedia is particularly interesting to cybermetric research because of the richness of phenomena and because its data is fully accessible.
Wikipedias: collaborative web-based encyclopedias as complex networks.
An analysis of Wikipedias in several languages as complex networks is presented, showing that many network characteristics are common to different language versions of Wikipedia, such as their degree distributions, growth, topology, reciprocity, clustering, assortativity, path lengths, and triad significance profiles.
Power of the Few vs . Wisdom of the Crowd : Wikipedia and the Rise of the Bourgeoisie
Although Wikipedia was driven by the influence of “elite” users early on, more recently there has been a dramatic shift in workload to the “common” user, and this is shown in, a very different type of social collaborative knowledge system.
Preferential attachment in the growth of social networks: the case of Wikipedia
An analysis of the statistical properties and growth of the free on-line encyclopedia Wikipedia is presented, which can be described by local rules such as the preferential attachment mechanism, though users, who are responsible of its evolution, can act globally on the network.
Temporal Analysis of the Wikigraph
This study characterize this evolution of the Wikipedia evolution in terms of users, editions and articles, and depicts the temporal evolution of several topological properties of the Wikigraph.
Collaborative Authoring on the Web: A Genre Analysis of Online Encyclopedias

A genre analysis of two web-based collaborative authoring environments, Wikipedia and Everything2, shows that the greater the degree of post-production editorial control afforded by the system, the more formal and standardized the language of the collaboratively-authored documents becomes, analogous to that found in traditional print encyclopedias.
Assessing Information Quality of a Community-Based Encyclopedia
This work proposes seven IQ metrics which can be evaluated automatically and test the set on a representative sample of Wikipedia content, along with a number of statistical characterizations of Wikipedia articles, their content construction, process metadata and social context.
Studying cooperation and conflict between authors with history flow visualizations
This paper investigates the dynamics of Wikipedia, a prominent, thriving wiki, and focuses on the relevance of authorship, the value of community surveillance in ameliorating antisocial behavior, and how authors with competing perspectives negotiate their differences.
Information quality work organization in wikipedia
This article analyzes the organization of IQ assurance work in a large-scale, open, collaborative encyclopedia—Wikipedia and believes that the study of those evolving debates and processes and of the IQ assurance model as a whole has useful implications for the improvement of quality in other more conventional databases.
Internet encyclopaedias go head to head
Jimmy Wales' Wikipedia comes close to Britannica in terms of the accuracy of its science entries, a Nature investigation finds.  UPDATE: see details of how the data were collected for this article in
