The Place of Issues (according to their edits and editors)

Research Question

The research inquires into the composition of issues on Wikipedia by contributors, and consequences for the (possibility) of carrying out public debate and controversy. Using link analysis, we mapped a network (or ecology) of articles surrounding Global Warming, and performed further analysis on a number of significant articles within it. In particular, we were interested in activity measures for highlighting where in the network debates (might) take place, as well as activity measures over time, in order to discover whether debates had moved from one article to another. Additionally, we were interested in the issue commitments of individual editors - the various Wikipedia contributors highly active within the larger Global Warming network. Do editors stick to a single article, or do they have preferred sets of articles? Such preferences would perhaps make it possible to 'profile' articles within the larger network, and offer a way to track the movement of debates across articles. Might the activity of a group of editors across a number of articles indicate a coordinated effort, or perhaps a particular distribution of the debate?

Methods and Findings

Global Warming Wikipedia Network

Method
  • Scrape the article 'Global Warming' for bi-directional links within Wikipedia (articles that both link to 'Global Warming' and are linked back to by it).
  • Scrape each of the resulting URLs for links to Wikipedia articles, outputting relational database.
  • Visualize with ReseaLu, highlighting articles used in further analysis.

Findings

The diagram displays the ecology of articles surrounding Global Warming on Wikipedia, based on links between articles. Nodes are sized according to number of links, shaped according to their role in the network (hubs appear in purple), and distributed according to their in- and outdegree centrality.

Thus one sees that the article Global Warming acts as a central node, connecting a dense cluster of articles related to climate change science (e.g. temperature records, key reports and concepts), to a looser, more heterogeneous network of articles, including some of the terms most popularly associated with the issue (Climate Change, Carbon Dioxide, Ozone Depletion, Kyoto Protocol and Renewable Energy). Notably, among this latter group are articles explicitly about the climate change debate: e.g. Scientific Opinion on Climate Change, Global Warming Controversy and Solar Variation (considered by the Wikipedian who created the article as "competition for 'global warming' theory").

One interpretation of the network comes from the hypothesis that structurally, Wikipedia networks may represent the free encyclopedia's desire to resolve controversy (an aim embodied, for example, in the NPOV policy, or 'Neutral Point of View'). From this perspective, one sees a separation of the popular debate surrounding the existence and causes of Global Warming from apparently factual articles. In further analyses (below), we asked whether the creation of certain new articles may be viewed as a form of controversy management, one that is specific to Wikipedia but may reflect similar processes brought to light in sociological studies of science and technology (Latour and Woolgar, 1979).

Network Topology: Article Activity

Question
How is activity (in terms of the number of edits) distributed within the network?

Method
For the analysis, we chose a sample of 16 articles strongly linked to the entries on Global Warming and Global Warming Controversy. The total number of edits per article were tallied, outputting an indication of the distribution of article activity within the network.

Findings
As may be expected, activity is distributed unevenly within the network, with the articles Global Warming, Kyoto Protocol and Global Warming Controversy being edited the most.

Network Topology: Article Activity Over Time

Question How have levels of activity changed over time, and what relationship may these have with Wikipedia's approach to dealing with debate and controversy?

Method
For each article, tally number of edits per month from November 2001 to July 2009.

Findings
In first instance, the visualization appears to indicate generic Wikipedia editing trends, such as the overall increase over the years, or the relative decrease in activity in the months of June and December, as well as an 'incubation' period between an article's creation and its maturation, with initial editing and a period of inactivity followed by more regular editing. More importantly for the analysis at hand, however, the heat map may be used to signal significant moments in Wikipedia's 'management' of the issue of Global Warming. For example, the high levels and subsequent decline of activity for the Global Warming and Global Warming Controversy articles in the first half of 2007 correspond to edit wars and the 'protection' of both articles (where protection refers to varying degrees of disallowing edits). Meanwhile, the creation of the article Scientific Opinion on Climate Change in September 2003 was followed by a decline in activity in the articles Global Warming and Climate Change. This event, in which it could be said that controversy was effectively managed and displaced, is explored below.
