# TiRoBERTa Fine-tuned for Tigrinya Abusive Language Detection

This model is a fine-tuned version of [TiRoBERTa](https://huggingface.co/fgaim/tiroberta-base) on the [TiALD](https://huggingface.co/datasets/fgaim/tigrinya-abusive-language-detection) dataset.

**Tigrinya Abusive Language Detection (TiALD) Dataset** is a large-scale, multi-task benchmark dataset for abusive language detection in the Tigrinya language. It consists of **13,717 YouTube comments** annotated for **abusiveness**, **sentiment**, and **topic** tasks. The dataset includes comments written in both the **Ge’ez script** and prevalent non-standard Latin **transliterations** to mirror real-world usage.

> ⚠️ The dataset contains explicit, obscene, and potentially hateful language. It should be used for research purposes only. ⚠️

This work accompanies the paper ["A Multi-Task Benchmark for Abusive Language Detection in Low-Resource Settings"](https://arxiv.org/abs/2505.12116).

## Model Usage

```python
from transformers import pipeline

tiald_pipe = pipeline("text-classification", model="fgaim/tiroberta-abusiveness-detection")
tiald_pipe("<text-to-classify>")
```

## Performance Metrics

This model achieves the following results on the evaluation set:

```json
"abusiveness_metrics": {
    "accuracy": 0.8666666666666667,
    "macro_f1": 0.8666502037288554,
    "macro_precision": 0.8668478260869565,
    "macro_recall": 0.8666666666666667,
    "weighted_f1": 0.8666502037288554,
    "weighted_precision": 0.8668478260869565,
    "weighted_recall": 0.8666666666666667
}
```

## Training Hyperparameters

The following hyperparameters were used during training:

- learning_rate: 2e-05
- train_batch_size: 16
- optimizer: Adam (betas=0.9, 0.999, epsilon=1e-08)
- lr_scheduler_type: linear
- num_epochs: 4.0
- seed: 42

## Intended Usage

The TiALD dataset and models designed to support:

- Research in abusive language detection in low-resource languages
- Context-aware abuse, sentiment, and topic modeling
- Multi-task and transfer learning with digraphic scripts
- Evaluation of multilingual and fine-tuned language models

Researchers and developers should avoid using this dataset for direct moderation or enforcement tasks without human oversight.

## Ethical Considerations

- **Sensitive content**: Contains toxic and offensive language. Use for research purposes only.
- **Cultural sensitivity**: Abuse is context-dependent; annotations were made by native speakers to account for cultural nuance.
- **Bias mitigation**: Data sampling and annotation were carefully designed to minimize reinforcement of stereotypes.
- **Privacy**: All the source content for the dataset is publicly available on YouTube.
- **Respect for expression**: The dataset should not be used for automated censorship without human review.

This research received IRB approval (Ref: KH2022-133) and followed ethical data collection and annotation practices, including informed consent of annotators.
