Problems about im2p evaluation

[yzpeng44]

Sorry for asking about im2p question here. Because I didn't find way to establish an issue in your im2p project.
I'm confused how to evaluate the paragraph generated by im2p.
Should I regard the whole paragraph (multi-sentences) as a large sentence and regard the ground truth as a sentence, either? Then put them into bleu, cider (and so on) to evaluate?
Or should I change the code of bleu.py and cider.py to evaluate the paragraphs by one sentence (generated) matching one sentence (ground truth)?
Hope you can help me with this! Thank you!
