Looked at a few papers over the weekend.
- This paper, "Inferring Social Ties across Heterogenous Networks" by
Jie Tang, Tiancheng Lou and Jon Kleinberg, talks about mapping labels of connections from one social networks to another. - First paper I have seen on daily deals "Daily Deals: Prediction, Social Diffusion, and Reputational Ramifications" describes detailed analysis of daily deals data from Groupon and Living Socials and correlates the data with Facebook/Twitter/Yelp data. Interestingly that they found that businesses that appear on daily deals site gain more reviews on Yelp by lose average ratings by 10%.
