基于加权LeaderRank的影响传播者识别

Identifying Influential Spreaders by Weighted LeaderRank

Qian Li, Tao Zhou, Linyuan Lv, Duanbing Chen

摘要:

识别有影响力的传播者对于理解和控制社交网络上的传播过程至关重要。通过将度相关权重分配到与地面节点相关联的链接上,我们提出了一种名为LeaderRank [L]的最近排名算法的变体。Lv等人,PLoS ONE 6(2011)e21202]。在标准SIR模型上的仿真结果表明,加权LeaderRank算法在三个方面优于LeaderRank算法:(i)发现更有影响力的传播者的能力,(ii)对噪声数据有更高的容忍度,(iii)对故意攻击有更高的鲁棒性。

英文摘要:

Identifying influential spreaders is crucial for understanding and controlling spreading processes on social networks. Via assigning degree-dependent weights onto links associated with the ground node, we proposed a variant to a recent ranking algorithm named LeaderRank [L. Lv et al., PLoS ONE 6 (2011) e21202]. According to the simulations on the standard SIR model, the weighted LeaderRank performs better than LeaderRank in three aspects: (i) the ability to find out more influential spreaders, (ii) the higher tolerance to noisy data, and (iii) the higher robustness to intentional attacks.
