Species: annotated species; Ontology: annotating GO ontology; num prot: number of annotated proteins in that species & ontology that are annotated by more than one paper. mean, stdv, stderr: mean number of consistent annotations for a protein in that species and ontology, standard deviation from the mean and standard error. num articles: number of annotating articles num terms number of annotating terms. Annotations by less than two articles or two terms (or both) for the same protein/ontology combination have been omitted.
