EMNLP2022_Explicit_Role_Interaction_Network

Here is the code for "Explicit Role Interaction Network for Event Argument Extraction".

Data preprocessing

1.Split datasets and preprocess data from ACE2005 preprocessing

2.Process the data into the format in ./data/ace/example.json. I add the flag id to indicate whether this event type is accurately classified in the upstream task

Event Detection

In this paper, we employ a pre-trained BERT model and stack a softmax layer.

Replace the golden start and end index of triggers with ED predicted results in both files dev.json and test.json.
