Binary evaluation method

We use sensitivity and specificity as statistical measures of the performance of the binary classification test where 
Sensitivity = Σ true different / (Σ true different + Σ false similar) 
and 
Specificity = Σ true similar / (Σ true similar + Σ false different) 
and the F-measure is calculated on this basis as shown in the table below: 

This is one suggested way which is nicely applicable if we test for binary correctness of calculations, i.e. it is applicable for characterisation and QA
