To set an appropriate goal of SMT research for Thai-based translation, the comparative study of potential and suitability between phrase-based translation (PBT) and hierarchical phrase-based translation (HPBT) becomes an initial question. Thai-Chinese language-pair is chosen as experimental subject since they share most of common syntactic pattern and Chinese resource is numerous. Based on standard setting, we gain a result that 3-gram HPBT gains significantly better BLEU point over 3-gram PBT while 3-gram HPBT is approximately equal to 5-gram PBT. Moreover, from the results, a Chinese-to-Thai translation obtains better accuracies than a Thai-to-Chinese translation from every approach. © 2012 IEEE.
