Detection of the elite structure in a virtual multiplex social system by means of a generalised K-core.

ABSTRACT: Elites are subgroups of individuals within a society that have the ability and means to influence, lead, govern, and shape societies. Members of elites are often well connected individuals, which enables them to impose their influence to many and to quickly gather, process, and spread information. Here we argue that elites are not only composed of highly connected individuals, but also of intermediaries connecting hubs to form a cohesive and structured elite-subgroup at the core of a social network. For this purpose we present a generalization of the K-core algorithm that allows to identify a social core that is composed of well-connected hubs together with their 'connectors'. We show the validity of the idea in the framework of a virtual world defined by a massive multiplayer online game,
