Code for ACL2021 paper paper 'Risk Minimization for Zero-Shot Sequence Labeling'.

Step 1: build config file

python train_source.py --config ner_en.config

Step 2: train source models(optional)

python train_source.py --config ner_en.config

Step 3: construct pseudo labeled dataset

python tools/cat_source_model.py

Step 4.1: Train LVM models

python train_finetune.py --config ner_3_en.config --method lvm --table multi_logits1

Step 4.2: Train MRT models

python train_finetune.py --config ner_3_en.config --method mrt --table multi_logits1
