ROUGE 2.0 is a Java Package for Evaluation of Summarization Tasks building on the Perl Implementation of ROUGE.
ROUGE stands for Recall-Oriented Understudy for Gisting Evaluation. It consists of a set of metrics for evaluating automatic summarization of texts as well as machine translation. It works by comparing an automatically produced summary or translation against a set of reference summaries (typically human-produced) or translations.
ROUGE 2.0 is a lightweight open-source tool that allows for easy evaluation of summaries or translation by limiting the amount of formatting needed in terms of reference summaries as well as system summaries. In addition, it also allows for evaluation of unicode texts known to be an issue with other implementations of ROUGE. One can also add new evaluation metrics to the existing code base or improve on existing ones.
