Researchers at MIT, Harvard University, Northeastern University, and Aix Marseille University have developed network maps that they say represent the strength of the cultural connections between speakers of different languages. The researchers analyzed data on multilingual Twitter users and Wikipedia editors and on 30 years’ worth of book translations in 150 countries. The researchers show that a language’s centrality in their network, defined by the number and the strength of its connections, predicts the global fame of its speakers better than the population or the wealth of the countries in which it is spoken.
