Evaluation Criteria

The primary evaluation metric will be area under the ROC curve (AUROC). F1 score (with a threshold of 0.5) will also be reported and analyzed. As such, some teams may wish to attempt combined classification and ranking methods. Note that the label 1 (denoting a mistake) is considered the "positive" class for both metrics.

The official AUROC and F1 metrics (plus a few others) are implemented in eval.py alongside the baseline code.

Terms and Conditions

All shared task participants are expected to submit a system paper describing their approach and results, to be presented at the BEA Workshop at the NAACL-HLT conference in June 2018. This paper will be published in the workshop proceedings and available through the ACL Anthology website.
