Societies can be represented as highly structured dynamic multiplex networks. Here we study the dynamical origins of the specific community structures of a large-scale social multiplex network of a human society that interacts in a virtual world of a massive multiplayer online game. There we find substantial differences in the community structures of different social actions, represented by the various layers in the multiplex network. Community sizes distributions are either fat-tailed or appear to be centered around a size of 50 individuals. To understand these observations we propose a voter model that is built around the principle of triadic closure. It explicitly models the co-evolution of node- and link-dynamics across different layers of the multiplex network. Depending on link and node fluctuation probabilities, the model exhibits an anomalous shattered fragmentation transition, where one layer fragments from one large component into many small components. The observed community size distributions are in good agreement with the predicted fragmentation in the model. This suggests that several detailed features of the fragmentation in societies can be traced back to the triadic closure processes. date: 2016-09 date_type: published publisher: IOP Publishing id_number: 10.1088/1367-2630/18/8/083045 creators_browse_id: 307 full_text_status: public publication: New Journal of Physics volume: 18 number: 8 pagerange: e083045 refereed: TRUE issn: 1367-2630 projects: multi-LAyer SpAtiotemporal Generalized NEtworks (LASAGNE, FP7 318132) projects: Foundational Research on MULTIlevel comPLEX networks and systems (MULTIPLEX, FP7 317532) coversheets_dirty: FALSE fp7_project: yes fp7_project_id: info:eu-repo/grantAgreement/EC/FP7/318132/EU/multi-LAyer SpAtiotemporal Generalized NEtworks/LASAGNE; info:eu-repo/grantAgreement/EC/FP7/317532/EU/Foundational Research on MULTIlevel comPLEX networks and systems/MULTIPLEX fp7_type: info:eu-repo/semantics/article access_rights: info:eu-repo/semantics/openAccess citation: Klimek, P., Diakonova, M., Eguíluz, V.M., San Miguel, M., & Thurner, S.
