Comparison of MedScan performance with other methods for automatic protein annotation reported in Blaschke et al  for BioCreAtIvE task 2.2. The figure is copied from Figure 4 of Blaschke et al  and MedScan performance added as one more method. Each point represents a single run submitted by the participants of task 2.2. User 1: Chiang et al. , 2: Couto et al. , 3: Ehrler et al. , 4: Ray et al. , 5: Rice et al. , 6: Verspoor et al. . MedScan performance was estimated by comparison with the protein-GO annotation extracted by human curators from European Bioinformatics Institute (EBI).
