an easy way for machine translation evaluation using multiple metrics

Kenneth Heafield's scripts that make it easy to score machine translation output using NIST's BLEU and NIST, TER, and METEOR.

Pre-requirements: bash, ruby, java
CAUTION: you have to set "export LC_ALL=" to let it work ("export LC_ALL=C" will make it crash)

Setup: run the ./ script which will automatically download necessary parts from Internet

./score.rb --print --print-header --ref tokenized-reference.txt --hyp-detok tokenized-system-outputs.txt
