This new language model trained on the quasi-corpus is then used together with the language model trained on the general-domain data (original training data) to produce a new list of N-best hypotheses under our self-enhancement framework.
an alternative solution for enhancing the translation model is through self-training (Ueffing, 2006;Ueffing et al., 2007) which re-trains the source-target N-best hypotheses together with the original training data, and thus differs from ours in the way of new phrase pairs extraction.
