You don't score the entire nbest lists. You extract the 1best
according to some linear weighting of the different model scores,
then score the 1best hypotheses you get .
Check the nbest-scripts(1) man page for a description of
There is also a tool to optimize the weights on a held-out set.
Check the nbest-optimize(1) command.
