PubTator3 GetEntityRelations
Query the NCBI PubTator3 relation knowledge graph for a normalized biomedical entity and return RANKED relation edges aggregated across all of PubMed. Given a single entity (e1), returns every related entity with the relation type (associate, cause, treat, prevent, inhibit, stimulate, interact, compare, drug_interact, negative_correlate, positive_correlate, etc.), the source/target entities, and the aggregate publication count supporting each edge. Edges are returned ranked by supporting public…
Overview
Query the NCBI PubTator3 relation knowledge graph for a normalized biomedical entity and return RANKED relation edges aggregated across all of PubMed. Given a single entity (e1), returns every related entity with the relation type (associate, cause, treat, prevent, inhibit, stimulate, interact, compare, drug_interact, negative_correlate, positive_correlate, etc.), the source/target entities, and the aggregate publication count supporting each edge. Edges are returned ranked by supporting publication count (highest first). This answers 'what is entity X related to, ranked by literature evidence' as a graph query, distinct from returning the articles themselves. Optionally pass a relation type and/or a second entity (e2) to query a specific pair (e.g. does chemical A treat disease B). Entities must use PubTator's normalized @TYPE_Name format, e.g. @GENE_BRAF, @DISEASE_Melanoma, @CHEMICAL_Doxorubicin. Use PubTator3_EntityAutocomplete to resolve free text into these normalized identifiers.
