Controlled Language Generation for Language Learning Items

This is the repository for the paper Controlled Language Generation for Language Learning Items at the Industry Track, EMNLP 2022. The code is based heavily on HuggingFace's sequence-to-sequence Trainer examples.

Requirements

Scripts were tested with python 3.9 and transformers version 4.6.1. Nothing else should be required.

Data

The data is provided as jsonlines objects containing relevant fields for concept-to-sequence generation with control. The files require Git LFS.

Training

To train, call the concept2seq.py script with --mode train, along with the required parameters. The "extras" parameter includes the control: this can be "srl", "wsd", "or "cefr".

# Set a root directory
r=/home/nlp-text/dynamic/kstowe/github/concept-control-gen/
data_json=${r}/data/concept2seq_train.jsonl

# Substitute in your python
/home/conda/kstowe/envs/pretrain/bin/python $r/concept2seq.py \
    --mode train \
    --data_dir $data_json \
    --output_dir $r/models/c2s_test \
    --epochs 3 \
    --batch_size 32 \
    --model_path facebook/bart-base \
#    --extras srl \

Prediction

Prediction works similarly, using the supported parameters.

        --output_path $r/outputs/test.txt \
        --test_path ${r}/data/concept2seq_test.jsonl \
