Figure 5. Accuracy of the Raw (Noncurated) Extracted Relations in the GeneWays 6.0 Database.

The accuracy was computed by averaging over all individual specific information extraction examples manually evaluated by the human curators. The plot compactly represents both the per-relation accuracy of the extraction process (indicated with the length of the corresponding bar) and the abundance of the corresponding relations in the database (represented by the bar color). There are relations extracted with a high precision; there are also many noisy relationships. The database accuracy was markedly increased by the automated curation outlined in this study (see Figure 9).
