内容简介:
Online health communities (OHCs) have become a major source of information and support for people with health problems. Using large-scale data from real-world OHCs, my research leveraged social network analysis, text mining, machine learning, as well as statistical modelling to study user behaviors in OHCs. In this talk, I will present my recent and ongoing research on influential user identification, users’ roles in social support, and users’ community engagement. I will also briefly introduce my studies of social and business networks in other domains.
