==== Abstract ====
Social and location recommendations are hot research topics as filtered suggestions are highly desirable to cope with information explosion problems when data being generated by mobile and socially connected users grow at a rapid pace.  In this keynote, I plan to present some of our recent work in social and Location recommendation based on a matrix factorization framework.  I will outline novel ways on how we can use social ensemble, trust relations, tags, click-through-rate, etc. to improve social and location recommender systems for a wide-range of applications and services.
