Imitating Manual Curation of Text-Mined Facts in Biomedicine
Figure 9
Accuracy and Abundance of the Extracted and Automatically Curated Relations
This plot represents both the per-relation accuracy after both information extraction and automated curation were done. Accuracy is indicated with the length of the relation-specific bars, while the abundance of the corresponding relations in the manually curated dataset is represented by color. Here, the MaxEnt 2 method was used for the automated curation. The results shown correspond to a score-based decision threshold set to zero; that is, all negative-score predictions were treated as “incorrect.” An increase in the score-based decision boundary can raise the precision of the output at the expense of a decrease in the recall (see Figure 8).
