People judge you by the words you use. This warning, once the slogan of a vocabulary building course, is now the mantra of the new science of culturomics.
In “Quantitative Analysis of Culture Using Millions of Digitized Books” (Michel, et al., Science, Dec. 17, 2010), a Harvard-led research team introduces “culturomics” as “the application of high throughput data collection and analysis to the study of human culture.” In plain English, they crunched a database of 500 billion words contained in 5 million books published between 1500 and 2008 in English and several other languages and digitized by Google. The resulting analysis provides insight into the state of these languages, how they change, and how they reflect culture at any given point in time.
