Hi Mauro, When you try to interpolate the LMs using the interpolate-LM script in IRSTLM, the initial file should not have the 'LMINTERPOLATION' flag... Only the final version should have it...
So initially your init file should look like: 2 0.5 /opt/tools/moses/scripts/ems/example/ex9watris/lm/Auto+Euro.lm.2 0.5 /opt/tools/moses/scripts/ems/example/ex9watris/lm/LMEN.lm.1 Then once you run the interpolation as specified in http://sourceforge.net/apps/mediawiki/irstlm/index.php?title=LM_interpolation you should end up with the final configuration file which looks like: 2 0.439053 /opt/tools/moses/scripts/ems/example/ex9watris/lm/Auto+Euro.lm.2 0.560947 /opt/tools/moses/scripts/ems/example/ex9watris/lm/LMEN.lm.1 NB: The weights here are simply dummy weights, in your case these could be completely different depending on your models and data... Now You manually need to Add the LMINTERPOLATION flag in the first line before 2. and then pass it on to Moses Decoder.... Ideally this flag should have been set by the lm-interpolate script itself but it is a bug which IRSTLM promised to fix in next releases...
