In this study, the amount of training parallel corpus was too large for us. So, we have a lot of time and a lot of memory to make a phrase-table. We had no time to optimize many parameters. If we have much times or memories, we would have been able to obtain a higher BLEU sore.
Our system was average performance for NTCIR-7 Patent Translation task. Our system was the 20th place in 34 system for Intrinsic-JE task and the 12th place in 20 system for Intrinsic-EJ task. So we will improve many points to get better score.
