But for University of Illinois researcher Kalev Leetaru, Wikipedia’s volumes of crowd-sourced articles are also an enormous dataset, one he mined for insights into the history of globalization. In total, he leveraged Wikipedia’s 37GB of English-language data, in particular the evolving connections between various locations across the globe over a period of years. “I put every coordinate on a map with a date stamp,” Leetaru told The New York Times. “It gave me a map of how the world is connected.” You can view the time lapse/data visualization on YouTube."
