Table 5: Span-level precision (P), recall (R) and F1-scores (F1) on four distinct baseline NER systems. All scores are computed as average over five-fold cross validation.
['[EMPTY]', 'CRF P', 'CRF R', 'CRF F1', 'BiLSTM CRF P', 'BiLSTM CRF R', 'BiLSTM CRF F1', 'MTL P', 'MTL R', 'MTL F1', 'BioBERT P', 'BioBERT R', 'BioBERT F1']
To evaluate the performance of the four systems, we calculate the span-level precision (P), recall (R) and F1 scores, along with corresponding micro and macro scores.
