Before revision:  In this paper,we address this gap by developing GraphReach, a position-aware , inductive GNN . GraphReach captures the global positions of nodes though reachability estimations with respect to a set of nodes called anchors. The reachability estimations compute the frequency with which a node may visit an anchor through any possible path. The anchors are strategically selected so that the reachability estimations across all  nodes are maximized.
