Figure 5

Assessing the quality of model alignments. The quality of model alignments increases with the fraction of annotated model elements. Alignments between BioModel 9 and BioModel 11 (see Figure 4) were compared to a manually chosen, correct alignment and scored by their recall (left boxes) and precision (right boxes). When annotations are randomly removed, recall and precision (y-axis) decrease with the fraction of removed annotations (x-axis). Boxes in different rows show results from alignments with direct similarities, FP similarities, and SP similarities, as well as a comparison of their three mean values. The straight lines in the three topmost boxes show trends and stem from a linear regression.
