aOnly curated chemical-gene interactions were analyzed (disease interactions were not considered); consequently, these numbers differ slightly from those reported in Table 2.
bPrecision = Correct interactions for individual biocurator/Total interactions for individual biocurator.
cRecall = Correct interactions for individual biocurator/Total correct interactions from all biocurators.
dF1-measure is the harmonic mean of precision and recall = (2 × Precision × Recall)/(Precision + Recall). Precision, Recall, and F1-measure were macro-averaged over the set of articles curated by that curator.
