Analyzing link dynamics in scientific collaboration networks ℄ A social yield based perspective

In this paper, we introduce social yield, a measure of collaboration success of the collaborating authors in a co-authorship network. We then attempt to empirically observe the link dynamics in collaboration networks induced by the social yield of the collaborations. Observation indicate that certain observed behavior like presence of large number of small sized communities and highly dynamic behavior of the links in collaboration networks can be explained based on the distribution of social yield of these collaborations. It is also observed that the distribution of social yield among the collaborations also affects the resilience of the collaboration networks to targeted link removal.
