This is the part where the classification is executed using the full text, profile, and gender information. The use of NamChar results in a slight improvement compared to the plain Threshold Classifier. This is a further 4.4 % reduction of the error rate compared to 0.892 of the Threshold Classifier without NamChar. The t-test shows that this difference between both results is significant, t(3,979)=2.04,p
