... l, d). 3.3 Lattice decoding We use Moses (Koehn et al., 2007) as a decoder for lattice decoding. Moses is an open source SMT system which allows lattice decoding. In lattice decoding, Moses selects ... decoder selects the best path for decoding. Us- ing these paraphrase lattices as inputs, we obtained significant gains in BLEU scores for IWSLT and Europarl datasets. 1 Introduction...
