Code repository for our EMNLP2023 paper "Adaptive End-to-End Metric Learning for Zero-Shot Cross-Domain Slot Filling"

We choose one target domain each time and the rest of domains are combined as source within SNIPS dataset under cross-domain setting. For zero-resource setting, we select CoNLL03 English NER as source dataset and SciTech NER as target dataset. Considering the cross-dataset setting, we select SNIPS as source(target) domain while ATIS as target(source) domain.

• We put the raw SNIPS dataset under data/raw_dataset/original_snips_data. The following commands might be useful for preparation:

cd YOUR_PATH_TO/zero-shot-slu
mkdir data/snips
python data/raw_dataset/preprocess_snips.py

• We also put the raw ATIS dataset under data/raw_dataset/atis. The following preprocessing commands are used for cross-dataset setting:

cd YOUR_PATH_TO/zero-shot-slu
mkdir data/merge_dataset
mkdir data/merge_dataset/snips
mkdir data/merge_dataset/atis
python data/dataPreprocessingM.py

• For SciTech NER dataset, please refer to this link and put the dataset under data/ner/tech folder.

mkdir bert_model
git lfs install
git clone https://huggingface.co/bert-base-uncased

We implement our method with Pytorch 1.8. Other required packages could be found in requirements.txt

• --tgt_dm: SNIPS target domain
• --n_samples: Number of samples used in the target domain, for K-shot, set n_samples to K
• --cl: using slot-level CL
• --cl_type: slot-level CL metric function
• --cl_temperature: slot-level CL temperature \tau
• --alpha: scalar coefficient of typing loss(L_typ) with default to 1.0
• --beta: scalr coefficient of slot-CL loss(L_ctr) with default to 1.0
• --model_ckpt: Saved model path
• --vocab_ckpt: Saved vocab path

Train our model for zero-shot adaptation to GetWeather domain:

❱❱❱ python slu_e2e_bert_f2train.py --cuda 0 -lr 1e-3 --n_sample 0 --tgt_dm GetWeather --epoch 30 --dropout 0.1 --cl --cl_type cosine --cl_temperature 0.5 --model_ckpt loss_log/test.ckpt --vocab_ckpt loss_log/test_vocab.ckpt

Train our model without slot-CL for zero-shot adaptation to GetWeather domain:

❱❱❱ python slu_e2e_bert_f2train.py --cuda 0 -lr 1e-3 --n_sample 0 --tgt_dm GetWeather --epoch 30 --dropout 0.1 --model_ckpt ckpt/end2end_cl/bert_domain_atp0.ckpt --vocab_ckpt ckpt/vocab/bert_domain_atp0_vocab.ckpt

Train our model for 50-shot adaptation to GetWeather domain:

❱❱❱ python slu_e2e_bert_f2train.py --cuda 0 -lr 1e-3 --n_sample 50 --tgt_dm GetWeather --epoch 30 --dropout 0.1 --cl --cl_type cosine --cl_temperature 0.5 --model_ckpt loss_log/test.ckpt --vocab_ckpt loss_log/test_vocab.ckpt

To train and evaluate our model under the cross-dataset scenario (i.e. SNIPS <-> ATIS), you can use the following commands:

❱❱❱ python f2xDataset.py --cuda 0 -lr 1e-3 --src snips --tgt atis --alpha 1.5 --beta 1.0 --epoch 30 --dropout 0.1 --cl --cl_type cosine --cl_temperature 0.5 --model_ckpt snips-atis.ckpt --vocab_ckpt snips-atis_vocab.ckpt
❱❱❱ python f2xDataset.py --cuda 0 -lr 1e-4 --src atis --tgt snips --batch_size 8 --alpha 2.0 --beta 2.0 --epoch 30 --dropout 0.1 --cl --cl_type euclidean --cl_temperature 0.5 --model_ckpt snips-atis.ckpt --vocab_ckpt snips-atis_vocab.ckpt

Train our model for zero-resource adaptation to sci-t ech domain

❱❱❱ python ner_e2e_train.py --cuda 0 -lr 1e-3 --n_sample 0 --tgt_dm tech --epoch 30 --dropout 0.5 --cl --cl_type cosine --cl_temperature 0.1 --model_ckpt test_tech.ckpt --vocab_ckpt test_vocab.ckpt

Train our model without slot-level CL for zero-resource adaptation to sci-tech domain

❱❱❱ python ner_e2e_train.py --cuda 0 -lr 1e-3 --n_sample 0 --tgt_dm tech --epoch 30 --dropout 0.5 --model_ckpt test_tech.ckpt --vocab_ckpt test_vocab.ckpt
