What is a good Rouge score?
ROUGE-n recall=40% means that 40% of the n-grams in the reference summary are also present in the generated summary. ROUGE-n precision=40% means that 40% of the n-grams in the generated summary are also present in the reference summary. ROUGE-n F1-score=40% is more difficult to interpret, like any F1-score.

Which is the best metric for text summarization?
Generally for summarization evaluation, only ROUGE-1 and ROUGE-2 (sometimes ROUGE-3, if we have really long gold and model summaries) metrics are used, rationale being that as we increase N, we increase the length of the N-gram word phrase that needs to be matched completely in both the gold and model summary.
