"Social Structure of Facebook Networks"
My "data dump" paper on Facebook networks is finally out in final form (including page numbers and all of the trimmings). Here is some information about it.
Title: Social Structure of Facebook Networks
Authors: Amanda L. Traud, Peter J. Mucha, and Mason A. Porter
Abstract: We study the social structure of Facebook ‘‘friendship’’ networks at one hundred American
colleges and universities at a single point in time, and we examine the roles of user
attributes – gender, class year, major, high school, and residence – at these institutions. We
investigate the influence of common attributes at the dyad level in terms of assortativity
coefficients and regression models. We then examine larger-scale groupings by detecting
communities algorithmically and comparing them to network partitions based on user
characteristics. We thereby examine the relative importance of different characteristics
at different institutions, finding for example that common high school is more important
to the social organization of large institutions and that the importance of common major
varies significantly between institutions. Our calculations illustrate how microscopic and
macroscopic perspectives give complementary insights on the social organization at
universities and suggest future studies to investigate such phenomena further.
