The TALP n-gram-based SMT system for IWSLT 2006

This paper describes TALPtuples, the 2006 Ngrambased statistical machine translation system developed at the TALP Research Center of the UPC (Universitat Politècnica de Catalunya) in Barcelona. Emphasis is put on improvements and extensions of the system of previous years, being highlighted and empirically compared. Mainly, these include a novel and much more efficient word ordering strategy based on reordering patterns, a linguistically-guided tuple segmentation criterion and improved optimization procedures. The paper provides details of this system participation in the third International Workshop on Spoken Language Translation (IWSLT) held in Kyoto, Japan in November 2006. Results on four translation directions are reported, namely from Arabic, Chinese, Italian and Japanese into English for the open data track, thoroughly explaining all language-related preprocessing and optimization schemes.
