形式化社交网络的多维性质

Formalising the multidimensional nature of social networks

David Lusseau, Louise Barrett, S. Peter Henzi

摘要:

个体在许多行为环境或维度中与同种个体互动。在这里,我们正式考虑一个社会网络n个人之间的互动,在b行为的维度作为一个nxnxb多维对象。此外,我们建议,这个对象的拓扑结构是由个人需要,以减少在一个或多个维度的相互作用的结果的不确定性。该建议的理由社会网络的动态和进化在个人选择过程中,并允许我们定义的不确定性的社会网络作为其组成的相互作用网络的联合熵。为了支持这些命题,我们使用模拟和自然的“淘汰”在一个自由放养的狒狒部队,以显示(i)这样的对象可以显示一个小世界的状态和(ii),如预测的那样,在社会扰动后的相互作用的变化导致一个更确定的社会网络,其中的相互作用的结果是更容易预测的成员。社交网络的这种新的形式化提供了一个框架,在此框架内预测网络动态和演变的假设下,它是由个人寻求减少他们的社会环境的不确定性。

英文摘要:

Individuals interact with conspecifics in a number of behavioural contexts or dimensions. Here, we formalise this by considering a social network between n individuals interacting in b behavioural dimensions as a nxnxb multidimensional object. In addition, we propose that the topology of this object is driven by individual needs to reduce uncertainty about the outcomes of interactions in one or more dimension. The proposal grounds social network dynamics and evolution in individual selection processes and allows us to define the uncertainty of the social network as the joint entropy of its constituent interaction networks. In support of these propositions we use simulations and natural 'knock-outs' in a free-ranging baboon troop to show (i) that such an object can display a small-world state and (ii) that, as predicted, changes in interactions after social perturbations lead to a more certain social network, in which the outcomes of interactions are easier for members to predict. This new formalisation of social networks provides a framework within which to predict network dynamics and evolution under the assumption that it is driven by individuals seeking to reduce the uncertainty of their social environment.
