Some machine learning papers, such as this one (see its abstract) express results on certain datasets as a percentage value called mAP. Could anyone explain the meaning of mAP?

mAP probably stands for mean Average Precision. The AP provides a measure of quality across all recall levels for single class classification, it can be seen as the area under the precision-recall curve. Then the mAP is the mean of APs in multi-class classification.
