hi somayeh if you change the LM order, you should change the ini file so the decoder knows the order of the LM. eg an LM of order 55: [lmodel-file] 0 0 55 /path/lm.srilm.gz it should go up. However, mert is random so its not guaranteed. Also, a higher order LM may make the decoder overfit the data it was trained on, so performance when translating unseen text may decrease. Espeically for out-of-domain text
