时序网络中基于顺序播种的有效影响传播

Effective Influence Spreading in Temporal Networks with Sequential Seeding

Radosław Michalski, Jarosław Jankowski, Piotr Bródka

摘要:

网络中的影响力传播在许多应用领域都是一个非常重要的话题。例如,人们希望最大限度地扩大覆盖面,限制营销活动初始化的预算,并利用社会影响力的潜力。为了解决这个问题和类似的挑战,十多年前,研究人员开始研究影响力最大化问题。挑战在于找到初始激活的种子节点的最佳集合,以最大化网络中的影响力传播。在典型的方法中,我们将在单个阶段激活所有种子,在这个过程的开始,而在这项工作中,我们介绍和评估一种新的方法,种子激活时序网络的基础上顺序播种。这种方法不是同时激活所有节点,而是分散种子的激活,从而导致更大范围的影响力传播。使用真实和随机网络进行的实验结果表明,所提出的方法在71%的情况下优于单阶段播种,平均近6%。知道时间网络是建模动态过程的适当选择,这项工作的结果可以被解释为鼓励将时间顺序播种应用于现实世界的情况下,特别是知道更复杂的种子选择策略可以通过使用本工作中引入的种子激活策略来实现。

英文摘要:

The spread of influence in networks is a topic of great importance in many application areas. For instance, one would like to maximise the coverage, limiting the budget for marketing campaign initialisation and use the potential of social influence. To tackle this and similar challenges, more than a decade ago, researchers started to investigate the influence maximisation problem. The challenge is to find the best set of initially activated seed nodes in order to maximise the influence spread in networks. In typical approach we will activate all seeds in single stage, at the beginning of the process, while in this work we introduce and evaluate a new approach for seeds activation in temporal networks based on sequential seeding. Instead of activating all nodes at the same time, this method distributes the activations of seeds, leading to higher ranges of influence spread. The results of experiments performed using real and randomised networks demonstrate that the proposed method outperforms single stage seeding in 71% of cases by nearly 6% on average. Knowing that temporal networks are an adequate choice for modelling dynamic processes, the results of this work can be interpreted as encouraging to apply temporal sequential seeding for real world cases, especially knowing that more sophisticated seed selection strategies can be implemented by using the seed activation strategy introduced in this work.
