German Opinion Role Labelling (ORLde)

---

Repository Description

This repository contains the code for our BERT model for German Opinion Role Labelling in Parliamentary Debates.

The code can be used to replicate our results from the paper:

Running the model

Get predictions for the test data, using the trained model from:

run 1:

python bert_orl.py orl-1-predict-bert.conf

run 2:

python bert_orl.py orl-2-predict-bert.conf

run 3:

python bert_orl.py orl-3-predict-bert.conf

You can evaluate the predictions by running:

python eval_predictions.py logfile_ORL_BERT_run_1.log 

python eval_predictions.py logfile_ORL_BERT_run_2.log 

python eval_predictions.py logfile_ORL_BERT_run_3.log 

Training a new model

You can train a new model on the training data and evaluate on the test set, using this script:

python bert_orl.py 

If you want to change the model parameters or input/output path, you need to change the config file ( orl-train-bert.conf)
