选址和观众选择,最大限度地扩大社会影响力

Location and audience selection for maximizing social influence

Balázs R. Sziklai, Balázs Lengyel

摘要:

病毒式营销活动主要针对那些在社交网络中处于中心地位并因此具有社会影响力的个人。然而,营销活动可能会吸引不同的受众。尽管事件营销的重要性,异质目标群体的影响还没有得到很好的理解。在本文中,我们定义的传播潜力(SP)的问题,其中不同的代理集需要评估和比较的基础上,他们的社会影响力。SP的一个典型应用是为一系列营销活动选择地点。SP问题在两个方面不同于众所周知的影响力最大化(IM)问题。首先,它处理的是集合而不是节点。第二,这一套是多样化的,由有影响力的和普通的代理人组成。因此,SP也需要评估普通代理人的贡献,而IM的目标只是找到顶级传播者。我们提供了一个系统的测试排名的影响措施在SP问题的基础上,节点抽样和一种新的统计方法,排名差异的总和。使用线性阈值扩散模型的在线社交网络,我们评估了七个网络的社会影响力的措施。我们表明,这些影响措施的统计评估是显着不同的SP问题,当低排名的个人存在,从IM问题,当我们专注于算法的首选完全。

英文摘要:

Viral marketing campaigns target primarily those individuals who are central in social networks and hence have social influence. Marketing events, however, may attract diverse audience. Despite the importance of event marketing, the influence of heterogeneous target groups is not well understood yet. In this paper, we define the Spreading Potential (SP) problem in which different sets of agents need to evaluated and compared based on their social influence. A typical application of SP is choosing locations for a series of marketing events. The SP problem is different from the well-known Influence Maximization (IM) problem in two aspects. Firstly, it deals with sets rather than nodes. Secondly, the sets are diverse, composed by a mixture of influential and ordinary agents. Thus, SP needs to assess the contribution of ordinary agents too, while IM only aims to find top spreaders. We provide a systemic test for ranking influence measures in the SP problem based on node sampling and on a novel statistical method, the Sum of Ranking Differences. Using a Linear Threshold diffusion model on an online social network, we evaluate seven network measures of social influence. We demonstrate that the statistical assessment of these influence measures is remarkably different in the SP problem, when low-ranked individuals are present, from the IM problem, when we focus on the algorithm's top choices exclusively.
