网络世界中大规模社交网络的多关系组织

Multirelational Organization of Large-scale Social Networks in an Online World

Michael Szell, Renaud Lambiotte, Stefan Thurner

摘要:

在网络媒体上收集个人指纹的能力彻底改变了研究人员探索人类社会的方式。社会系统可以被看作是众多复杂社交网络的非线性叠加,其中节点代表个人,链接捕捉各种不同的社会关系。社会互动的网络拓扑结构一直是研究的重点,然而,这些互动的多维性在很大程度上被忽略,主要是因为缺乏数据的实证研究。在这里,我们第一次分析了一个完整的,多关系的,大型的社会网络,这个社会由一个大型多人在线游戏的30万多名玩家组成。我们提取了玩家之间六种不同类型的一对一互动的网络。其中三个具有积极的含义(友谊,沟通,贸易),三个具有消极的含义(敌意,武装侵略,惩罚)。我们首先将这些类型的网络作为独立的实体进行分析,发现负相互作用与正相互作用的不同之处在于它们的低互惠性,较弱的聚类性和厚尾度分布。然后,我们继续探索不同网络类型的相互依赖性如何决定社会系统的组织。特别是,我们研究不同类型的链接之间的相关性和重叠,并展示了个人在不同网络中扮演不同角色的趋势。作为一个示范的力量的方法,我们提出了第一个经验性的大规模验证的长期存在的结构平衡理论,通过专注于特定的多元网络的友谊和敌意的关系。

英文摘要:

The capacity to collect fingerprints of individuals in online media has revolutionized the way researchers explore human society. Social systems can be seen as a non-linear superposition of a multitude of complex social networks, where nodes represent individuals and links capture a variety of different social relations. Much emphasis has been put on the network topology of social interactions, however, the multi-dimensional nature of these interactions has largely been ignored in empirical studies, mostly because of lack of data. Here, for the first time, we analyze a complete, multi-relational, large social network of a society consisting of the 300,000 odd players of a massive multiplayer online game. We extract networks of six different types of one-to-one interactions between the players. Three of them carry a positive connotation (friendship, communication, trade), three a negative (enmity, armed aggression, punishment). We first analyze these types of networks as separate entities and find that negative interactions differ from positive interactions by their lower reciprocity, weaker clustering and fatter-tail degree distribution. We then proceed to explore how the inter-dependence of different network types determines the organization of the social system. In particular we study correlations and overlap between different types of links and demonstrate the tendency of individuals to play different roles in different networks. As a demonstration of the power of the approach we present the first empirical large-scale verification of the long-standing structural balance theory, by focusing on the specific multiplex network of friendship and enmity relations.
