persuasive_essays_distilbert_cased

Model description

This model is a fine-tuned version of distilbert-base-cased on the emnlp2017-claim-identification/persuasive_essays dataset. It achieves the following results on the evaluation set:

• Loss: 0.4249
• Accuracy: 0.8101
• Macro F1: 0.7662
• Claim F1: 0.665

Intended uses & limitations

Text classification for claims on full sentences. The model perfoms better at in-domain classification. Cross-domain classification is severely limited.

Training and evaluation data

Based on Stab and Gurevych (2017) persuasive essays corpus, preprocessed by Daxenberger et al. (2017).
