NY POST - June 20 - Dating app Once wants its users to know precisely how dateable they are. It uses a new transparent and perhaps harsh algorithm-driven system. "Ranking algorithms" are the unspoken secrets of the dating industry," said Once CEO Jean Meyer. "We know we're doing it, we know our competition is doing it, so why not be transparent?" Meyer says knowing one's rank in the dating world can help users target more realistic matches. To understand its ranking algorithm, it helps to picture a game: If a poor player suddenly beats a skilled one, their rating rises. So if someone with a low rating suddenly matches with a total hottie, they inch closer to a 5. 4s and 5s have a lot of power, he adds: "The higher you rank, the more weight your likes have." OkCupid denied ranking users, and Bumble would not speak of its algorithm.
