# persuasive_essays_distilbert_uncased

## Model description

This model is a fine-tuned version of [distilbert-base-uncased](https://huggingface.co/distilbert-base-uncased) on the [emnlp2017-claim-identification/persuasive_essays](https://github.com/UKPLab/emnlp2017-claim-identification) dataset.
It achieves the following results on the evaluation set:
- Loss: 0.4314
- Accuracy: 0.8001
- Macro F1: 0.7510
- Claim F1: 0.6403

## 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)](https://aclanthology.org/J17-3005.pdf) persuasive essays corpus, preprocessed by [Daxenberger et al. (2017)]((https://github.com/UKPLab/emnlp2017-claim-identification).

Original dataset
  - docs: 402
  - tokens: 147,271
  - total instances: 7,116 (65 duplicates)
    - #claims: 2,108 (29.62%)

Trimmed datast used for training
  - total instances: **7051** (65 duplicates removed)
    - #claims: **2093** (29.68%)
  - train/test split: 80/20, stratified
