Usage

Setup

1. Create a new environment:

conda create --name disrpt python=3.8
conda activate disrpt

2. Install dependencies:

pip install -r requirements.txt

3. Ensure the 2021 shared task data is at data/2021/.

Experiments

Gold segmentation:

bash seg_scripts/single_corpus_train_and_test_ft.sh zho.rst.sctb

Silver segmentation:

bash seg_scripts/silver_single_corpus_train_and_test_ft.sh zho.rst.sctb

Relation classification:

bash rel_scripts/run_single_flair_clone.sh zho.rst.sctb

Troubleshooting

Batch size may be modified, if necessary, using the batch_size parameter in:

• configs/seg/baseline/bert_baseline_ft.jsonnet
• configs/seg/baseline/bert_baseline_ft_silver.jsonnet
• configs/rel/flair_clone.jsonnet
