Table 12: The macro F1-scores gained with different values of k when tested on the ILI 2018 development set.
['[ITALIC]  [BOLD] k 1', '[BOLD] Macro F1-score 0.954', '[ITALIC]  [BOLD] k 32 or 48', '[BOLD] Macro F1-score 0.964']
with different values of k on the development set using the same parameters with the HeLI 2.0 method as for the baseline. On the development set, k=64 gave the best F1-score, 0.964, which is an absolute increase of 0.010 on the original F1-score. The corresponding recall was 96.29%, which was a bit better than the 96.22% obtained in the shared task.
