Brief introduction of the report:
This talk discusses the algorithmic process of creating relationships in social networks. We think of a social network as a graph structure where nodes represent the participants of the social network and edges represent connections that allow direct interaction between two participants. Making connections is very important to social networking in different ways. From the perspective of individual participants, making connections enables individuals to gain centrality and thus a more favorable position in the social network. From a group perspective, making connections enhances interactions and resolves differences, thus facilitating the emergence of "global norms" - unified actions among agents. From the perspective of the network as a whole, making connections fills so-called "structural holes" and dissolves the fabric of the community. In this talk, we will present a series of recent work describing these three perspectives mathematically and discuss the corresponding algorithmic problems.
