About one-hop neighborhood context and two-hop monophily #3

方便起见,我还是用中文吧。 您的工作简洁高效,符合直觉,先👍一个。 论文6.2中有这样的一句:“we attribute our significant improvement to modeling the one-hop neighborhood context and two-hop monophily.” 有一个疑问是这样的: "two-hop monophily"应该是"one-hop neighborhood context"的补充吧?大多数情况下"two-hop monophily"都会属于"one-hop neighborhood context"的,除了一些例外(比如一个结点只有一个邻居,就没有这种"one-hop neighborhood context"可言)

Thank you for your interest. Some two-hop neighbors share similar semantic features but do not share similar one-hop neighborhood contexts in the real world, especially when we have multi-class (n>2) or the graph shows mixture patterns.

I get it, you're right, we must consider situations like multi-class. Thanks for your reply :)
