Setup

Here, ${TASK} representes the source and target language pair, and "ja-ko" can be applied.
We assume that there are reference files (${TASK}.txt) in tests.org/, translation result files (${TASK}.txt) in results.org/ and all tools in ${path}.
TASK=ja-ko
SCRIPT=${path}/script.segmentation.distribution
MOSES_SCRIPT=${path}/mosesdecoder-RELEASE-2.1.1/scripts
RIBES=${path}/RIBES-1.02.4
mkdir tests.tok
mkdir results.tok

Segmentation

  • MeCab-ko

    • for file in tests results; do
      cat ${file}.org/${TASK}.txt | \
       perl -Mencoding=utf8 -pe 's/(.)［[０-９．]+］$/${1}/;' | \
       perl ${SCRIPT}/h2z-utf8-without-space.pl | \
       mecab -O wakati | |
       perl -Mencoding=utf8 -pe 'while(s/([０-９]) ([０-９])/$1$2/g){} s/([０-９]) (．) ([０-９])/$1$2$3/g; while(s/([Ａ-Ｚ]) ([Ａ-Ｚａ-ｚ])/$1$2/g){} while(s/([ａ-ｚ]) ([ａ-ｚ])/$1$2/g){} s/ $//;' \
       > ${file}.tok/${TASK}.mecab.txt
    done

    Evaluation

  • BLEU

    • for segmenter in mecab; do

    done

  • RIBES

    • for segmenter in mecab; do
      python3 ${RIBES}/RIBES.py -c -r tests.tok/${TASK}.${segmenter}.txt results.tok/${TASK}.${segmenter}.txt
