To reach this goal, we adopt a max-margin framework (Socher et al., 2010;Socher et al., 2011a;Socher et al., 2013) for training.
suppose we have a training data like (u i , G(u i ), A(u i )), where u i is the input source sentence, G(u i ) is the gold derivation set containing all gold derivations of u i 1 , and A(u i ) is the possible derivation set that contains all possible derivations of u i .
