Description
想请教一下，在我的数据集上，DeepWalk的效果远好于Line(2nd order)。DeepWalk离线mrr可以达到0.7+, Line只有0.2+，二者都是无监督Loss。想请教下，这种情况是什么原因呢？我的graph是item同构图，node百万，连边亿级。谢谢。

Research direction
No source file, test, or entry point is named. First identify the DeepWalk and LINE (2nd-order) implementations and compare their training objectives and graph sampling on the stated million-node, hundred-million-edge item graph. Done would require a project-grounded explanation for the reported MRR gap.
