There are two steps to run this code:

• Preprocessing: using file jee_processData.py

You will need to have the ACE 2005 data set in the format required by this file. We cannot include the data in this release due to licence issues. A sample document is provided in data.

• Train and test the model: using file evaluateJEE.py

This step takes the output file in step 1.

There are various parameters of the model you can change directly in the evaluateJEE.py file.
