                 摘 要: 近年来, 由于异质图卷积网络能够有效学习异质网络语义信息, 逐渐成为网络节点分类的主流算法, 但仍
                 面临诸多挑战: 现有的大多数工作主要集中在普通异质网络上, 即假设两个节点之间只有一种类型的边, 忽略了多
                 层异质网络中多类型节点间的多重关系, 以及没有显式地探索不同关系对各类节点表征的影响. 此外, 图神经网络
                 的过平滑问题也限制了现有模型仅能捕获低阶的局部信息, 几乎无法学习网络的全局相关信息. 为了应对这些挑
                 战, 提出了一种面向节点分类的多层异质图神经网络                 (multiplex heterogeneous graph neural network, MHGNN). 具体
                 来说, MHGNN   首先学习各类节点在不同关系下的局部初始表征, 再显式地探索不同关系下的表征的重要性以及
                 有效融合不同关系下各类型节点的表征, 从而捕获多层异质网络中不同交互关系的差异性. 其次, 基于微观经济学
                 中的替代品和互补品概念, 构造了考虑全局相似性特征的替代品和互补品矩阵, 并通过图神经网络进行信息聚合,
                 以更好地捕获不同关系下各类节点之间的高阶全局语义信息. 最后, 通过对比学习协调局部和全局两个视图中学
                 习到的差异性和相似性表征并融合获得最终节点表征. 在                   6  个真实数据集上的广泛实验评估证明所提的              MHGNN
                 在节点分类任务上的各项评估指标都显著优于最新模型.

                 Abstract:  In recent years, heterogeneous graph convolutional networks have emerged as a mainstream approach for node classification due
                 to  their  ability  to  effectively  capture  semantic  information  in  heterogeneous  networks.  However,  several  challenges  remain.  Most  existing
                 studies  focus  on  general  heterogeneous  networks,  where  only  a  single  type  of  edge  is  assumed  between  any  two  nodes.  This  simplification
                 overlooks  the  multiple  relationships  that  exist  among  multi-type  nodes  in  multiplex  heterogeneous  networks  and  fails  to  explicitly  explore
                 the  impact  of  different  relations  on  the  representations  of  various  node  types.  Moreover,  the  over-smoothing  issue  inherent  in  graph  neural
                 networks  limits  these  models  to  capturing  only  low-order  local  information,  making  it  difficult  to  learn  global  correlation  patterns  in  the
                 network.  To  address  these  challenges,  this  study  proposes  a  multiplex  heterogeneous  graph  neural  network  (MHGNN)  designed  for  node
                 classification.  The  proposed  MHGNN  first  learns  local  initial  representations  of  each  node  type  under  different  relational  contexts.  It  then
                 explicitly  models  the  importance  of  each  relation  and  effectively  integrates  the  representations  of  different  node  types  across  multiple
                 relations,  thus  capturing  the  relational  diversity  within  multiplex  heterogeneous  networks.  In  addition,  drawing  inspiration  from  the
                 microeconomic  concepts  of  substitutes  and  complements,  the  study  constructs  substitute  and  complement  matrices  that  encode  global
