A full Python librarie for the ROUGE metric (paper).
This implementation is independant from the "official" ROUGE script (aka. ROUGE-155).
Results may be slighlty different, see discussions in #2.

usage: rouge [-h] [-f] [-a] hypothesis reference
Rouge Metric Calculator
positional arguments:
hypothesis Text of file path

e.g.
# Single Sentence
rouge "transcript is a written version of each day 's cnn student" \
"this page includes the show transcript use the transcript to help students with"
# Scoring using two files (line by line)
rouge -f ./tests/hyp.txt ./ref.txt
# Avg scoring - 2 files
rouge -f ./tests/hyp.txt ./ref.txt --avgfrom rouge import Rouge
hypothesis = "the #### transcript is a written version of each day 's cnn student news program use this transcript to he lp students with reading comprehension and vocabulary use the weekly newsquiz to test your knowledge of storie s you saw on cnn student news"
reference = "this page includes the show transcript use the transcript to help students with reading comprehension and vocabulary at the bottom of the page , comment for a chance to be mentioned on cnn student news . you must be a teac her or a student age # # or older to request a mention on the cnn student news roll call . the weekly newsquiz tests students ' knowledge of even ts in the news"
rouge = Rouge()
scores = rouge.get_scores(hypothesis, reference)Output:

import json
from rouge import Rouge
# Load some sentences
with open('./tests/data.json') as f:
data = json.load(f)
hyps, refs = map(list, zip(*[[d['hyp'], d['ref']] for d in data]))
rouge = Rouge()
scores = rouge.get_scores(hyps, refs)
# or
scores = rouge.get_scores(hyps, refs, avg=True)Output (avg=False): a list of n dicts:
[{"rouge-1": {"f": _, "p": _, "r": _}, "rouge-2" : { .. }, "rouge-l": { ... }}]
Output (avg=True): a single dict with average values:
{"rouge-1": {"f": _, "p": _, "r": _}, "rouge-2" : { .. }, "rouge-l": { ... }}
Given two files hyp_path, ref_path, with the same number (n) of lines, calculate score for each of this lines, or, the average over the whole file.
from rouge import FilesRouge
files_rouge = FilesRouge()
scores = files_rouge.get_scores(hyp_path, ref_path)
# or
scores = files_rouge.get_scores(hyp_path, ref_path, avg=True)
