MedErrBench (English) - Error Localization: leaderboard
Metric: Localization accuracy (%): naming the sentence that contains the error (an error-free note must be answered 'NA', which counts as correct when the gold label is NA); 208 English test notes adapted from MedQA cases (104 with an error, 104 without) with clinician-verified inserted errors; main-table prompting (the paper does not state its shot setting); printed as fractions and shown times 100; higher is better.
