Reasoning on the knowledge graph (KG) aims to infer new facts from existing
ones. Methods based on the relational path have shown strong, interpretable,
and transferable reasoning ability. However, paths are naturally limited in
capturing local evidence in graphs. In this paper, we introduce a novel
relational structure, i.e., relational directed graph (r-digraph), which is
composed of overlapped relational paths, to capture the KG's local evidence.
Since the r- digraphs are more complex than paths, how to efficiently construct
and …
