The TRGTK's System Description of the PatentMT Task at the NTCIR-10 Workshop

This paper introduces the TRGTK’s system for Patent Machine Translation at the NTCIR-10 Workshop. In this year’s program, we participate Chinese-English, English-Japanese and Japanese-English three subtasks. We submit required system results for Intrinsic Evaluation (IE), Patent Examination Evaluation (PEE), Chronological Evaluation (ChE), and Multilingual Evaluation (ME). Different from last year’s strategy, we focus on developing a strong and practical system for large-scale machine translation requirements. We design parallel algorithm for Chinese word segmentation, weights tuning and translation decoding, especially we propose a documental level translation method to improve the translation quality of special terms. Experimental results show that our system reduce the training and decoding time while still achieve promising translation results.
