Learning to Infer Social Ties in Large Networks⋆

In this work, we investigate to what extent social relationships can be inferred from the online social networks: E.g., given users’ behavior history and interactions between users, can we estimate how likely they are to be family members? There exist a few related studies. For example, Diehl et al. ...
