In the table, ‘classification threshold’ is the threshold of the Logistic regression classifier with 110 RDE features. The ‘filtering threshold’ is the number of n most relevant high-level GO classes to the sentence determined by the classifiers. If the highest ranked GO term by GORank is in the n classes, it will be selected as a positive result.
