Comparison of SIPs and eTBLAST in the detection of duplicate publications

% eTBLAST (ratio 0.46) SIPs (ratio 0.1)
Sensitivity (recall) 50.3 78.9
Specificity 99.8 99.6
Positive predictive value (precision) 87.8 84
Negative predictive value 99.3 99.4
F-measure 63.7 81.4

F-measure is the harmonic mean f precision and recall.
