Training

The training process is as follows.

1. Parallel Corpus

   We prepare a Japanese-English parallel corpus.

2. Rule-based Machine Translation

   We used a Japanese-English rule-based machine translation. Thus, we obtain "ENGLISH" sentences from Japanese sentences. These "ENGLISH" sentences are pairs of English sentences.

3. "ENGLISH"-English phrase table

   We make an "ENGLISH"-English phrase table using training-phrase-model.perl[14].

4. English $N$ -gram model

   We make an $N$ -gram model from English sentences using SRILM [6].
