Two-view Graph Neural Networks for Knowledge Graph Completion. (arXiv:2112.09231v2 [cs.CL] UPDATED)

We present an effective GNN-based knowledge graph embedding model, named WGE,
to capture entity- and relation-focused graph structures. In particular, given
the knowledge graph, WGE builds a single undirected entity-focused graph that
views entities as nodes. In addition, WGE also constructs another single
undirected graph from relation-focused constraints, which views entities and
relations as nodes. WGE then proposes a GNN-based architecture to better learn
vector representations of entities and relations from these two single entity-
and relation-focused graphs. WGE feeds …
