Network properties and social sharing of emotions in social awareness streams

The relationship between social sharing of emotions, social networks and social ties is an ongoing topic of research. Such sharing of emotions occurs frequently in “social awareness streams ” platforms like Twitter and Facebook.

Our analysis suggests that expression of emotion can explain some of the variance in users ’ Twitter networks, and that the use of emotion in interactions between users is a strong explaining factor
