The prediction accuracy of using neighbor counting, χ2, and SVM when predicting GO terms.

For SVM, it's the average accuracy of a leave-one-domain-out cross-validation. “Top 1” (“Top 3”) indicates when “the top one ranked GO term” (“one of the top three ranked GO terms”) matches one of the actual GO terms of the target domain, it is considered a correct prediction. The values shown under “Top 1” are also the precision values for top 1 prediction. The precision values for “Top 3” predictions can be found at Table 4.
