On Tie Strength Augmented Social Correlation for Inferring Preference of Mobile Telco Users

no code implementations1 Mar 2016 Shifeng Liu, Zheng Hu, Sujit Dey, Xin Ke

Based on a real world telecom dataset including CDRs and preference of more than $550K$ users for several months, we verified that correlation does exist between online preference in such \textit{ambiguous} social network.
