Illustration of hierarchical attention approach used in the steps of the network schema view embedding (i.e., NSVE-1 and NSVE-2), with focus on the target entity \(M_{1}\) in different layers. From left to right, NSVE-1 box shows node-level attention w.r.t. target nodes \(M_{1}\), with colored lines denoting different relations and matching different attention weights; NSVE-2 box shows type-level attention w.r.t. target nodes \(M_{1}\), with different colors, resp. textures, denoting the embeddings obtained from different relations, resp. layers, and across-layer attention w.r.t. target nodes \(M_{1}\), combining the embeddings of different layers
