Not surprisingly, most studies claim that their method performs as well or better than the best-performing competing methods. In practice, each study typically compares to a handful of other methods. These : Performance comparisons using the nine-species benchmark dataset. In the graph, each arrow represents a performance comparison carried out using the high-resolution version of the nine-species benchmark dataset . An arrow from method A to B implies that A outperformed B. In each case, the comparison was reported in the paper describing method A. The comparisons in the graph represent a variety of different performance measures, including the area under the precision-recall curve, area under the precision-coverage curve, peptide-level precision at 100% coverage (i.e., peptide-level accuracy), or the Position-BLEU score . Note that some comparisons are excluded from the graph because they use the low-resolution version of the nine-species benchmark or they only employed a subset of the species in the benchmark .
