  1. Columns with 1, 3, 5 and 10 present top-1, top-3, top-5 and top-10 accuracies, respectively. Column “Percentage(%)” represents the percentage of reactions in the test set belonging to the specific reaction type. “-” represents that the corresponding results are not available due to the lack of coverage.
