Knowledge Graph Completion Based on Half-Edge Principle [PDF]

Jisuanji gongcheng, 2020
Existing knowledge graph completion algorithms are time-consuming and inaccurate.To address these problems,this paper proposes a multi-layer convolution model based on half-edge.The model introduces the half-edge principle,and uses the descriptive ...
