We used the dev1 set for parameter tuning, the dev2 set for choosing the setting of the proposed method, which is described below, and the dev3 set for test- ing. The ... recognition. Thus, the translation quality for lattice inputs is better than the quality for 1- best inputs. In this paper, we show that lattice decoding is also useful...
