Rouge Score

[Hannibal046]

Hello. Could you please tell the rouge score in your paper is r, p or f? And for bart baseline , did you do any preprocessing like deleting \n\r or add some special tokens ? thanks

Hi, we use F-score for ROUGE. For baseline data, I upload them to here, under the clean_samsum dir.

Thanks for your reply. When reproducing your results, I find that rouge1 and 2 can exactly match your report, but rouge-l is 1 point lower, there must be something wrong with my metric_testing function, could you please help me ?

the hyps.txt and golden.txt are from this repository

BTW, wouldn't the lowercase of name in your golden.txt hurt the rouge score since the names in your output are uppercased ?

Hi, py-rouge does lowercase inside the pkg: https://github.com/Diego999/py-rouge/blob/16f225b1f46e9d382f1bf5170546da218ee98003/rouge/rouge.py#L697 and I provide the test code, have you tried this one? https://github.com/xcfcode/PLM_annotator/blob/main/bart/py_rouge_test.py

Hi, I got it ! I used your test_code and get the results. But in py-rouge, the hyps and refs used \n, and I tried your example , get following results, is this more accurate? Thanks

[Hannibal046]

And it seems a bug in py-rouge to set weight_factor in terms of rouge-l,https://github.com/Diego999/py-rouge/issues/10

Thanks for your information, how do you get the above results, could you please show me some details, the rouge-l score looks much higher.

On my side, I just run python py_rouge_test.py -c summaries/samsum.txt

you can simply add

candidates = [x.replace(' . ',' . \n') for x in candidates]
references = [x.replace(' . ',' . \n') for x in references]

in your py_rouge_test.py,and you can get a higher rouge-L. below is the official code example from py-rouge, we can notice that every sentence is appended with a \n
