Table 9: The macro F1-scores gained with different values of k when evaluated on the development set.
['[ITALIC]  [BOLD] k 1', '[BOLD] Macro F1-score 0.659', '[ITALIC]  [BOLD] k 52, 54, or 55', '[BOLD] Macro F1-score 0.774']
with different values of k, the number of parts the examined mystery text collection is split into, on the development set using the same parameters with the HeLI 2.0 method as for the baseline. On the development set, k=57 gave the best F1-score, with the absolute increase of 0.116 over the baseline. The corresponding recall was 77.74%, which was somewhat lower than the 77.99% obtained at the shared task.
