                 多数现有方法专注于局部结构或节点嵌入不同, 通过在统一框架内对节点、子图和整个图之间的复杂关系                                    (即局
                 部-全局关系和节点相关性) 进行建模来捕捉图结构. 这有助于更好地理解图的拓扑结构, 并利用结构自监督信号.

                 Abstract:  This  study  aims  to  learn  robust  graph  representations  from  unlabeled  graph  data.  A  novel  framework,  termed  structural  relation
                 modeling  (SRM),  is  proposed  for  self-supervised  graph  representation  learning  to  alleviate  inherent  limitations  caused  by  unlabeled  data
                 and  graph  topological  imbalances.  First,  rather  than  focusing  solely  on  local  structures  or  node  embeddings  as  in  most  existing  methods,
                 this  study  models  complex  structural  relations,  such  as  local-global  relations  and  node  correlations,  among  nodes,  subgraphs,  and  entire
                 graphs  within  a  unified  framework  to  better  capture  graph  topology  and  utilize  structural  self-supervision.  Second,  a  partition-based
                 subgraph  sampling  mechanism  is  introduced  to  mitigate  over-aggregation  and  topological  decay  induced  by  graph  topological  imbalance,
                 enabling  more  uniform  information  propagation  through  mini-batch  training.  Third,  a  node  regularization  strategy  is  applied  to  improve
                 training  stability  and  efficiency,  resulting  in  more  accurate  structural  representations.  Extensive  experiments  on  node  and  graph
                 classification across 12 public datasets demonstrate the effectiveness and generalizability of the proposed method.
