Anming Li, HARETON K. N. LEUNG, Yvette Lui · 2014
Although social network had been identified as an effective way to enhance overweight and obesity intervention in literature, the specific measures for integrating social network and weight loss are very limited until now. In this study, we developed a measure for recommending friends for weight loss apps in the context of social networks. In addition to network and profile similarities that have been well documented, our measure provided methods to model weight gain related behaviors and used obtained scores to construct a "behavior network". For evaluation, we proposed two measurements and conducted an experiment on a real dataset complemented with computer generated social graph. Results validated that presented measure is able to recommend friend conducting healthier lifestyle when compared with other friend recommendation measures.
