Number of high-precision predictions among GO terms for which precision can be confidently estimated. Number of currently annotated (green) versus predicted genes (orange, predictions expected to be correct; gray, predictions expected to be incorrect) for a subset of Gene Ontology (GO) terms for which 30% precision on held-out annotations was achieved while recovering at least 10 positives in the held-out set. The number of predicted genes displayed was limited to 1,000. GO terms were ordered according to similarity of prediction/annotation patterns. Terminal digits of GO term identifiers are shown in parentheses. GO-BP, GO Biological process; GO-CC, GO Cellular component; GO-MF, GO Molecular function.
