More details about the Rouge

[zhaochaocs]

Hi, I am really interested in this paper and hope to understand how you get the rouge. Could you provide more details about that? Do you use the original ROUGE-1.5.5.pl or any other implementations? Any preprocessing before the matching? (Say, converts to lower case, remove stopwords, stemming, etc) And any sentence reordering when calculating ROUGE-L? Thanks.
