How to run

pip install -r requirements.txt

There are two variants of ComparER model: subjective and objective.

Run ComparER on Subjective Aspect-Level Quality

Run MTER model:

python mter.py

MTER is the base model of ComparER with subjective aspect-level quality. After finish training MTER, we can continue train ComparERSub by the command:

python comparer_sub.py

Run ComparER on Objective Aspect-Level Quality

Run EFM model:

python efm.py

EFM is the base model of ComparER with objective aspect-level quality. After finish training EFM, we can continue train ComparERObj by the command:

python comparer_obj.py
