From: CNN-based ranking for biomedical entity normalization

Mention Baseline system CNN-based ranking system
Tremulousness Normalized into ‘tremors’ by sieve 7. Normalized into ‘trembles’ by ranking entities in E=E2={tremors, tremulous, neonatal tremor, NIL } with scores {0.9311, 0.9652, 0.0191, 0.0526}.
Tremulous Normalized into ‘tremulous’ by sieve 1. Normalized into ‘tremulous’ by ranking entities in E=E2={tremulous } with scores {1.0}.
Metaplastic polyps of the colorectum Normalized into ‘polyps’ by sieve 10. Normalized into ‘colorectal polyps’ by ranking entities in E=E3={adenomatous polyps in the colon, colonic polyps, adenomatous polyps of the colon and rectum, colorectal polyps, polyps, adenomatous polyps } with scores {0.0088, 0.0079, 0.0133, 0.0656, 0.0077, 0.0010}.
