"...I wanted to get a picture not only of what Wikipedia articles pointed at the Paris Review, but also Paris Review interviews which were not referenced in Wikipedia. So I wrote a little crawler that collected all the Paris Review interviews, and then figured out which ones were pointed at by English Wikipedia."
"These links indicate individuals who have co-edited many pages together on Wikipedia. We use a custom weighting technique, and filter down to the core editors (in every language except Egyptian Arabic and Swahili where we use everyone). The fact that this core is so well connected indicates the coherence of the Wikipedia community."
"At the global scale (in an article that we currently have under review), we found that the number of Wikipedia articles within (or describing) a country can be explained to a large degree by just three factors: (1) the size of its population, (2) the number of its fixed broadband internet connections, and (3) the number of edits committed to Wikipedia by its population."
"I am a highly visual person. When I have to learn something new, I usually first try to make a sketch of the structure of the knowledge that I want (or have to ;-)) to study. This usually results in diagrams outlining the material, giving it some structured form that makes it easier for me to grasp. "
"In this case the nodes in the network are wikipedia articles and the edges are the links between articles. We then ... used an algorithm to lay out all 650,000 nodes (wikipedia articles) that had at least one link in such a way that similar articles are near one another. These are the yellow dots, which when viewed at low res give a yellow tint to the whole picture."
"First, this study introduces the Flow Circle, which is a new exploratory data analysis tool devised to solve such problems of History Flow. Second, this tool is used to actually visualize the Wiki revision history regarding gun politics in order to understand and analyze the flow of the revision history and the relationship and conflict structures between the authors based on the results of the MDS analysis."

"A while ago, Wikipedia introduced georeferences. Georeferences are a way to annotate geographic landmarks, borders, [and] cities within Wikipedia articles ... Wikipedia Worldview is an app to project Wikipedia georeferences onto a 2D plane, intended to analyze the language-based distribution."
"The clustering component of this visualization is vital. The mere presence of information isn't all that interesting; there is no context or relevance to be gleaned. However, the structure of information is revealing about where fields intersect and diverge, and ultimately about how humans organize information."
"We analyzed and visualized Article for Deletion (AfD) discussions in the English Wikipedia. The visualization above represents the 100 longest discussions that resulted in the deletion of the respective article. "
"Since geography is never far from history, a lot of maps show the colonial past of many countries. As ethnic groups don’t always fall inside political borders, several maps reveal the presence of multiple ethnic or cultural groups within a country or of groups stretching across borders."

"Wikistream is a Node.js webapp for helping visualize current editing activity in Wikipedia. It uses Node.js, socket.io and Redis to sit in the wikimedia IRC chat rooms (where updates are published), and makes them available on the Web in realtime."
