Impact of Unary-Network and Pairwise-Network in terms of the F1-score (%)

Settings	BC5CDR-Chemical	BC5CDR-Disease	NCBI-Disease
Unary-CRF	93.01	86.14	86.94
Pairwise-CRF	93.27	86.05	86.71
Unary+Pairwise ensemble	93.25	86.78	87.09
DTranNER	94.16	87.22	88.62

Note: “Unary-CRF” denotes a variant model excluding Pairwise-Network from DTranNER, “Pairwise-CRF” denotes a variant model excluding Unary-Network from DTranNER, and “Unary+Pairwise ensemble” is an ensemble model of “Unary-CRF” and “Pairwise-CRF.” In the ensemble model, “Unary-CRF” and “Pairwise-CRF” were independently trained, and they voted over the sequence predictions by their prediction scores
