We have analyzed the complete network of an online
social networking service, Cyworld. In addition, we have also
analyzed sample networks from Cyworld, orkut, and MySpace
in terms of degree distribution, clustering coefficient, degree
correlation, and average path length.
We report a multi-scaling behavior in Cyworld’s degree distribution
and have substantiated our claim that heterogeneous
types of users are the force behind the behavior with detailed
analysis of the clustering coefficient distribution, assortativity
(or disassortativity), and the historical evolution of the network
size, the average path length, and the effective diameter. The
observation that the scaling exponents of MySpace and orkut
match those from different regions in the Cyworld network is
also worthy of note.
