This curves summarize the tradeoff between the true positive rate and the positive predictive value.

A high area under the curve represents both high recall and high precision.

Recall is synonymous with specificity, and precision is identical with positive predictive value.

Precision-recall curves tend to be more informative when you have imbalanced classes.
