资料原文

Dating apps like Bumble and Tinder can help singles couple up. But online dating is also great for scientists. "There's so much folk wisdom about dating and very little hard evidence." Elizabeth Bruch is a computational social scientist at the University of Michigan. She recently used online dating data to answer this question: "What does it mean for someone to be out of your league, and is there a way that we can study that using the techniques of network science?" Bruch and her colleague Mark Newman studied who swapped messages with whom on a popular online dating platform in the month of January 2014. They categorized users by desirability using PageRank, one of the algorithms behind search technology. Essentially, if you receive a dozen messages from desirable users, you must be more desirable than someone who receives the same number of messages from average users. Then they asked: How far "out of their league" do online daters tend to go when pursuing a partner?
