The corpus was divided into 5 partitions to carry out a cross-validation approach.
the probability for the child node associated to e i = w i @u j is given by No change in the computation of the probability of the child node is produced when the output is empty (i.e., p(,@b|Yes)=0.7 p=0  p=0.0392 p=0.0392 p=0.0392 p=0.0392 .
