# Generative Ranking

Ranking in Taobao's Guess You Like service no longer generates a list over a truncated single-business candidate set and then hands it to cross-business blending. UGR generates one list over roughly a thousand organic, ad and other-business candidates per request, models historical ad exposure separately during training, and adds current ad value at serving. In an online A/B test on Guess You Like, UGR raised Core IPV by 1.76%, Transaction Volume by 3.29% and GMV by 2.10% over the production baseline.
