Performance gain of the proposed NERs (with all dictionaries) trained on the created silver corpus against the same NERs trained on domain-related, gold standard corpora
| Category | Gold standard corpus | Precision | Recall | F-score |
|---|---|---|---|---|
| Chemical | BioCreative IV CHEMDNER | +34.11 | −10.40 | +19.13 |
| Gene | BioCreative II Gene Mention | +23.91 | −4.28 | +18.48 |
| Disease | NCBI Disease | +3.30 | +0.74 | +2.60 |
Note: F-score gain is statistically significant (P-value <0.01) for all categories. Values in percentage points.
