Title: Online Constrained Ranking for Large Scale Content Recommendation

Abstract: Personalized content recommendation is at the core of many of the user facing products at Yahoo and in almost all other online content serving companies. Users need to be matched with interesting content in near real-time while simultaneously achieving business targets. In this talk, I will describe the details of a large-scale recommendation system and involved challenges. We will talk about how constraints are put on the recommendation and ranking algorithms via either quality or business requirements. This constraint ranking is formulated as a Linear Program and solved in an online fashion every time a user is served content. Finally, we will go over some theoretical guarantees when we solve the proposed LP approximately via a primal-dual formulation.
