NTCIR-9 PATMT showed the effectiveness of my translation technology, “RIBES” and “Head Finalization“.

RIBES
Automatic evaluation method of translation quality for distant language pairs such as English and Japanese.
You can download RIBES from NTT.
RIBES is the acronym of “Rank-based Intuitive Bilingual Evaluation Score”.
NTCIR-9 PATMT’s overview paper compares RIBES with BLEU and NIST. According to their Table 19 on p.573, BLEU and NIST are not appropriate to measure translation quality between English and Japanese.
They have very weak negative correlation with human evaluation.
Head Finalization
A very simple rule to reorder English into Japanese and similar word order languages. By this rule, English is reordered just like Japanese.
Then, Statistical Machine Translation works without the severe word-order problem.
My new paper, “HPSG-based Preprocessing for English-to-Japanese Translation”, was accepted by ACM TALIP in August 2011. It will be published in September 2012.
