Errors of interaction pair extraction. The figure shows the distribution of errors in the interaction pair extraction. The blue ellipse contains 798 annotated pairs, the yellow ellipse 8,172 coincident pairs, and the green circle 339 extracted pairs. I, 100 true-positive samples; II, 166 coincident but false-negative samples; III, 239 false-positive samples; IV, 7,135 true-negative samples; V, 532 false-negative samples but never coincident.
