The defaults are set the way that BLEU should be computed, and furthermore, the script outputs a short version string that allows others to know exactly what you did.Īs an added bonus, it automatically downloads and manages test sets for you, so that you can simply tell it to score against wmt14, without having to hunt down a path on your local file system.
SacreBLEU aims to solve these problems by wrapping the original reference implementation ( Papineni et al., 2002) together with other useful features. On top of this, downloading and managing test sets is a moderate annoyance. All of these may handle tokenization in different ways. Different flags passed to each of these scripts can produce wide swings in the final score.
Moses itself has a number of implementations as standalone scripts, with little indication of how they differ (note: they mostly don't, but expects tokenized input). Every decoder has its own implementation, often borrowed from Moses, but maybe with subtle changes. MotivationĬomparing BLEU scores is harder than it should be. It also knows all the standard test sets and handles downloading, processing, and tokenization for you. Inspired by Rico Sennrich's multi-bleu-detok.perl, it produces the official WMT scores but works with plain text.
