ROUGE Score

The `rouge-score` library is a pure Python implementation of the ROUGE-1.5.5 evaluation metric, designed to closely replicate the results of the original Perl script. It provides functionalities for calculating ROUGE-N, ROUGE-L (sentence-level and summary-level), text normalization, and optional Porter stemming. The library is currently at version 0.1.2, released in July 2022, and while the version updates are infrequent, it remains an actively used and stable package maintained by Google for evaluating text generation tasks like summarization.
