摘要(Abstract):
在复杂网络中,对重要节点进行排序可以识别网络中的核心与关键节点,对调控传播过程具有重要意义。目前已有许多关于重要节点排序的研究,但如何高效、全面地利用节点信息提取特征并评估节点重要性,仍需进一步探索。本文结合节点的局部与全局信息,提出一种基于图神经网络(graph neural network, GNN)的重要节点排序方法。首先,利用节点的度、节点间最短距离和k-shell值,捕获节点的局部与全局信息;其次,获取节点信息后,采用图注意力机制聚合邻居节点特征,并学习节点的表示向量;最后,通过全连接层计算节点重要性。本文在真实网络数据集上进行实验,采用单调性指数(monotonicity index, MI)和肯德尔τ系数验证所提方法的有效性。实验结果表明,该模型在不同的网络结构中均能有效地对网络重要节点进行排序。
