Fig. 4: Impact of each component in the KGE_NFM framework on predictive performance in the scenario of the warm start in the unbalanced situation.

a and b represent the ROC and PR curves on the Yamanishi_08’s dataset, respectively. b and d represent the ROC and PR curves on the BioKG dataset, respectively. Specifically, KGE_NFM_nodes means that the KGE_NFM framework does not incorporate the information of traditional characterization.
