From: An integrated approach to the prediction of domain-domain interactions
The relationship between rank and true positive rate (TP/(TP+FP)) compared to the iPfam for four species based on four score functions. "Expectation" ranks domain pairs according to the expected number of occurrences of domain pairs in protein interactions; "Probability" ranks domain pairs according to the estimated probability of interactions from the MLE method; "Frequency" ranks domain pairs according to the number of protein interactions having domain pair; "E-value" ranks domain pairs according to the E-value defined in [1].
