Self-organization Leads to Hierarchical Modularity in an Interenet Community
Hallinan, J.
Proceedings of 7th International Conference on Knowledge-Based Intelligent Information and Engineering Systems(KES2003)Abstract:
Many naturally-occurring networks share topological characteristics such as scale-free connectivity and a modular organization. It has recently been suggested that a hierarchically modular organization may be another such ubiquitous characteristic. In this paper we introduce a coherence metric for the quantification of structural modularity, and use this metric to demonstrate that a self-organized social network derived from Internet Relay Chat (IRC) channel interactions exhibits measurable hierarchical modularity, reflecting an underlying hierarchical neighbourhood structure in the social network.
