We developed a two-stage MT system. The first stage consists of an automatically created PBMT system. The second stage consists of an SMT system. Our goal with this system is to obtain fewer ungrammatical sentences.
We obtained a BLEU score of 0.5201 in the BTEC-FE task using our proposed system. In contrast, we obtained a BLEU score of 0.5077 in the BTEC-FE task using a standard SMT system (Moses). This means that our proposed system is effective in the BTEC-FE task. Also, our proposed system obtained an above average BLEU score compared to all participating systems. However, our system placed 7th out of 9 systems.
There are many points for improving PBMT. For future work, we will focus on such improvements.
