Personalized Ranking Model Adaptation for Web Search - Microsoft Research
Search engines train and apply a single ranking model across all users, but searchers’ information needs are diverse and cover a broad range of topics. Hence, a single user-independent ranking model is insufficient to satisfy different users’ result preferences. Conventional personalization methods learn separate models of user interests and use those to re-rank the results from the generic model.
