Since the original summarization metric ROUGE is made only for English, we follow the method of Hu et al. and map words in other languages to numbers.
Languages without spaces (eg. Chinese, Japanese) will be segmented by characters and others will be split by spaces. For example, the Chinese text is split by characters, and the English words and numbers will be split by space.

chmod +x $PYROUGE_HOME_DIR/ROUGE-1.5.5.plEach line in candidate/reference file should be a summary in the language ('-l') that consisting of sentences split by the delimiter (-d). '-t' indicates whether the text needs to be tokenized.

If you have problem in using ROUGE, you can check the complete installation commands.
sudo apt-get install libxml-perl libxml-dom-perl
pip install git+git://github.com/bheinzerling/pyrouge

chmod +x $PYROUGE_HOME_DIR/ROUGE-1.5.5.plWe have put the RELEASE-1.5.5 in the directory 'ROUGE-1.5.5'. You can also download here by yourself. Remember to build Wordnet 2.0 instead of 1.6 in RELEASE-1.5.5/data:
# remove old files
rm $PYROUGE_HOME_DIR/data/WordNet-2.0-Exceptions/WordNet-2.0.exc.db
rm $PYROUGE_HOME_DIR/data/WordNet-2.0.exc.db
# create new files by yourself
cd $PYROUGE_HOME_DIR/data/WordNet-2.0-Exceptions/
perl ./buildExeptionDB.pl . exc WordNet-2.0.exc.db
cd ../
ln -s WordNet-2.0-Exceptions/WordNet-2.0.exc.db WordNet-2.0.exc.db
