您好,
针对每条rule, 需要为每个user找到要进行GCN传播的路径。
关于这块,我基于您的工作在自己的数据集上定义了一条user-item的元路径,提前从包含user-item interaction的KG中,把user-item之间按照元路径的通路所涉及的所有三元组挑选了出来,去重后根据这个子KG集合构建邻接矩阵,基于此进行GCN的传播,是否与您的算法思路是一致?

谢谢!

您好!
这里您定义的user-item的元路径,相当于我们这里的一条rule。针对单条rule (或者user-item的元路径) 采用GCN传播聚合从而得到user的表示,您说的做法和我们的思路是基本一致的。
祝好!
