This repository has a pytorch implementation of transition-based model for discontinuous NER, introduced in our ACL 2020 paper:
Xiang Dai, Sarvnaz Karimi, Ben Hachey, and Cecile Paris. 2020. An Effective Transition-based Model for Discontinuous NER. In ACL, Seattle, Washington.
Once you download the dataset, you can use script data/cadec/build_data_for_transition_discontinuous_ner.sh to build the dataset.
The script used to train the model on CADEC can be found in code/xdai/ner/transition_discontinuous/cadec.sh
