Dependencies

Install pytorch, transformers, tensorboardX, and Googletrans

conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch-nightly -c nvidia
pip install transformers==2.9.1
conda install tensorboardX
pip install googletrans==3.1.0a0

XQA-DST Experiments in the paper

Zero-shot Domain Adaptation Experiments

1. First define the excluded domain in the file examples/example.train.xlmr.multiwoz.adaptation
2. Execute the following script that will do the leave-1-out domain adaptation experiment for you.

sh examples/example.train.xlmr.multiwoz.adaptation 

Zero-shot Cross-Lingual Experiments

1. First train the XLM-R on WOZ 2.0 English datasets. We start from the checkpoint of the XLM-R trained on SQuAD 2.0

sh examples/example.train.xlmr.squad

2. Define the best learned checkpoint in 'model_name_or_path'. Transfer it to GE and IT. Notice the Googletrans process is time-consuming.

sh examples/example.test.cross.lingual.it
sh examples/example.test.cross.lingual.de

Supervised DST Experiments

1. We first train the independent domain classifier using files ending with domain_classifier_multiple

sh examples/example.train.xlmr.multiwoz.classifier

2. Then train the main model independently.

sh examples/example.train.xlmr.multiwoz

3. Then load them together within the arguments of the file example.test.xlmr.combine, which should generate evaluation results.

sh examples/example.test.xlmr.combine

Datasets

Supported datasets are:

• WOZ 2.0
• MultiWOZ 2.1

The prepared and processed datasets for this work is 'preprocessed_data.zip'. Please unzip it to the data/ folder for your convenience.

Partial codes are modified from TripPy: A Triple Copy Strategy for Value Independent Neural Dialog State Tracking

Backlog:

1. Add support for new multi-lingual ToD datasets.
2. Replace the framework to the newest version of Huggingface transformers.
