a A screenshot of the annotation platform that allowed expert annotators to select the relation types for different candidate relations in all of the sentences. The example sentence shown describes a prognostic marker. b An overview of the annotation process. Sentences are identified from literature that describes cancers, genes, variants, and optionally drugs before being filtered using search terms.

Each task had a test phase and then the main phase on the 800 sentences that were used to create the gold set
