On Sharing Preferences in Social Networks

摘要

In this paper, we study sharing in online social networks through the lens of resource-allocation. Specifically, we study whether people with large networks share as much as people with small networks. Our work shows three influencing factors in content-sharing inequality: individual sharing tendencies, sharing tendencies of one's friends, and content relevance. We then show that, content shared by an individual is determined by the number of his/her friends who are frequent sharers; thus, network composition plays a role in content-sharing.
