This paper reports on the participation of ITC-irst to the evaluation campaign of the International Workshop on Spoken Language Translation 2006. Our two-pass system is the evolution of the one we employed for the 2005 campaign: in the first pass, an N-best list of translations is generated for each source sentence by means of a beam-search decoder; in the second pass, N-best lists are rescored and reranked exploiting additional feature functions. Main updates brought to the 2005 system involve novel additional features which are here described. Results on development sets are analyzed and commented.

This paper reports on the participation of ITC-irst to the evaluation campaign of the International Workshop on Spoken Language Translation 2006.

Main updates brought to the 2005 system involve novel additional features which are here described. Results on development sets are analyzed and commented.File in questo prodotto:
