在构造测试文本。

在终端文件夹~/mtworkdir/mosesdecoder/lixiang1中：

/home/xdj/mtworkdir/mosesdecoder/scripts/tokenizer/tokenizer.perl -l en <b.en> b.tok.en

/home/xdj/mtworkdir/mosesdecoder/scripts/tokenizer/tokenizer.perl -l en <b.cn> b.tok.cn

/home/xdj/mtworkdir/mosesdecoder/scripts/recaser/train-truecaser.perl --corpus b.tok.en --model b.model.en

/home/xdj/mtworkdir/mosesdecoder/scripts/recaser/train-truecaser.perl --corpus b.tok.cn --model b.model.cn


/home/xdj/mtworkdir/mosesdecoder/scripts/recaser/truecase.perl --model b.model.en<b.tok.en>b.true.en

/home/xdj/mtworkdir/mosesdecoder/scripts/recaser/truecase.perl --model b.model.cn<b.tok.cn>b.true.cn


/home/xdj/mtworkdir/mosesdecoder/scripts/training/clean-corpus-n.perl b.true cn en b.clean 1 80

80代表分词的个数。本数据可取30。


 /home/xdj/mtworkdir/irstlm/irstlm-master/scripts/add-start-end.sh <b.clean.cn>b.sb.cn

/home/xdj/mtworkdir/irstlm/irstlm-master/scripts/add-start-end.sh <b.clean.en>b.sb.en


运行时报错如下：

　　　Set irstlm

　　这里要声明IRSTLM的安装路径：

 export IRSTLM=/home/xdj/mtworkdir/irstlm


/home/xdj/mtworkdir/irstlm/irstlm-master/scripts/build-lm.sh -i b.sb.cn -t ./tmp -p -s improved-kneser-ney -o b.lm.cn

/home/xdj/mtworkdir/irstlm/irstlm-master/scripts/build-lm.sh -i b.sb.en -t ./tmp -p -s improved-kneser-ney -o b.lm.en


/home/xdj/mtworkdir/irstlm/bin/compile-lm --\text=yes b.lm.cn.gz b.arpa.cn

/home/xdj/mtworkdir/irstlm/bin/compile-lm --\text=yes b.lm.en.gz b.arpa.en

关键参考：https://github.com/irstlm-team/irstlm/issues/2 


/home/xdj/mtworkdir/mosesdecoder/bin/build_binary b.arpa.cn b.blm.cn

/home/xdj/mtworkdir/mosesdecoder/bin/build_binary b.arpa.en b.blm.en
