Lattice minimum Bayes-risk (LMBR) decoding has been applied successfully to translation lattices in traditional SMT to improve translation performance of a single system (Kumar and Byrne, 2004;Tromble et al., 2008;.
minimum Bayes-risk (MBR) decoding is also a very powerful framework for combining diverse systems (Sim et al., 2007;de Gispert et al., 2009).
