Abstract:

The AI and Big Data Era has ushered in a new wave of research that investigates how we can better handle data with characteristics such as high volume, velocity, veracity, and variety using machine learning techniques.  Social Computing examines the collective intelligent behavior resulted from interactions among social entities.  In the first part of the talk, the speaker plans to draw some observations on the interplay between Social Computing and Big Data. The speaker will then focus on our recent work on social and location recommendations based on matrix factorization framework as a case study that demonstrates how filtered suggestions are highly desirable to cope with the information explosion problem.  The speaker 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 in the era of Big Data.
