The PubMed Knowledge Graph (PKG) is a large-scale biomedical knowledge graph derived from PubMed. It links papers to disambiguated authors, bio-entities, affiliations, citation relationships, and research projects, enabling bibliometric and scientometric analyses across the biomedical literature.
PKG 2.0 extends the graph by connecting papers with patents and clinical trials, integrating previously dispersed biomedical resources through biomedical entity links, author networks, citation relationships, and research project connections. The dataset is freely available for download from the project homepage.
