Changes in the AUCs of the three data sources with different numbers of neighbors (30–120). Via comparison, we find that although the AUC values of three data sources are the highest under 30 neighbors, drug repositioning is a prediction task rather than a simple classification task, and we need more neighbors to provide information. Thus, we choose 50 as the number of neighbors
