Data used for manual evaluation of precision:

Please note that not all gene synonymys in the following pages are supposed to be of the same organism.

e.g. In the page of Arabidopsis thaliana you will find the following sentence:

Expression of AtKT2 rescued growth on low millimolar [K+] in Saccharomyces cerevisiae carrying deletions for the genes encoding the K+ transporters TRK1 and TRK2. (PMID: 9350997)

Only the first synonym AtKT2 is from Arabidopsis the other two genes (TRK1 and TRK2) are from Saccharomyces cerevisiae.
The system detected all three genes correctly, thus also to their correct organisms. Since the page in question is used to asses the precision for Arabidopsis genes, a score of 1 true positive was counted.
