Model Checkpoints

Checkpoints trained from this repo are shared for the WikiEvents dataset and the ACE dataset are available at: [s3://gen-arg-data/checkpoints/].

You can download all the contents from the S3 bucket using AWS cli: aws s3 cp s3://gen-arg-data/checkpoints/ ./ --recursive

Model Predictions

The model predictions on WikiEvents is provided in outputs/wikievents-pointer-pred. Running this file through the scorer.py function should give you the exact same numbers as Table 5.

Datasets

• RAMS (Download at [https://nlp.jhu.edu/rams/])
• ACE05 (Access from LDC[https://catalog.ldc.upenn.edu/LDC2006T06] and preprocessing following OneIE[http://blender.cs.illinois.edu/software/oneie/])
• WikiEvents (Available here [s3://gen-arg-data/wikievents/])

You can download the data through the AWS cli or AWS console. Alternatively, you can download individual files by

• wget https://gen-arg-data.s3.us-east-2.amazonaws.com/wikievents/data/<split>.jsonl for split={train, dev,test}.
• wget https://gen-arg-data.s3.us-east-2.amazonaws.com/wikievents/data/coref/<split>.jsonlines for split={train, dev, test}.

Additional processed test files for RAMS can be downloaded by

• wget https://gen-arg-data.s3.us-east-2.amazonaws.com/RAMS/test_head_coref.jsonlines
• wget https://gen-arg-data.s3.us-east-2.amazonaws.com/RAMS/test_head.jsonlines
