NTT SMT System 2008 at NTCIR-7

This paper describes NTT SMT System 2008 presented at the patent translation task (PAT-MT) in NTCIR-7. For PAT-MT, we submitted our strong baseline system faithfully following a hierarchical phrasebased statistical machine translation [2]. The hierarchical phrase-based SMT is based on a synchronousCFGs in which a paired source/target rules are synchronously applied starting from the initial symbol. The decoding is realized by a CYK-style bottom-up parsing on the source side with each derivation representing a translation candidate. We demonstrate the strong baseline for the PAT-MT English/Japanese translations.
