The results are shown in Table 3.
we looked at: (i) combining the two classifiers without training set enlargement or boosting of the literal class (combined), (ii) boosting the literal class with 200 automatically labelled non-canonical form examples (combined+boost), (iii) enlarging the training set by iteration (com-bined+it), and (iv) enlarging the training set by iteration and boosting the literal class after each iteration (combined+boost+it).
