Ranking evaluation script. This script is written for the purposes of Quality Estimation Ranking in the field of Machine Translation, but it could in principle work for other tasks[1]. It also adopts a few metrics from the IR ranking shared task organized by Yahoo a few years ago. This script is under testing and development, so please refer to the source file for further explanations and citations

Requirements: Set your PYTHONPATH to the src/ directory Python 2.7 with numpy

Example commadline :

python src/evaluation/rankeval.py myfile.jcml predicted_rank rank

'predicted_rank' and 'rank' are the names of the rank attribute on the sentence level. Before running the script you should add the rank your QE predicted in the XML element of the target sentence. It should therefore look like

<judgedsentence ...> <src ...>... <tgt rank='1' predicted_rank='3' ..> <tgt rank='2' predicted_rank='4' ..> ...

There is also a iPython notebook that demonstrates how to use it for tasks outside of Machine Translation.
