WebAUCPR is an average of the precision-recall weighted by the probability of a given threshold. The main difference between AUC and AUCPR is that AUC calculates the area under the ROC curve and AUCPR calculates the area under the Precision Recall curve. The Precision Recall curve does not care about True Negatives.
