Real-world data medical knowledge graph: construction and applications

作者:

Highlights:

• This paper proposes a systematic approach to construct medical KG from EMRs.

• The constructed KG contains 9 entity types, totally 22,508 entities and 579,094 quadruplets.

• Quadruplet structure is proposed to represent a fact in the real-world KG.

• The proposed ranking function PSR achieves the best performance under all relations.

• The obtained KG is successfully applied to several practical applications.
