# <a name="introduction"></a>ViHateT5: Enhancing Hate Speech Detection in Vietnamese with A Unified Text-to-Text Transformer Model | ACL'2024 (Findings)
**Disclaimer**: This paper contains examples from actual content on social media platforms that could be considered toxic and offensive.

ViHateT5-HSD is the fine-tuned model of [ViHateT5](https://huggingface.co/tarudesu/ViHateT5-base) on multiple Vietnamese hate speech detection benchmark datasets.

The architecture and experimental results of ViHateT5 can be found in the [paper](https://aclanthology.org/2024.findings-acl.355.pdf):

The pre-training dataset named VOZ-HSD is available at [HERE](https://huggingface.co/datasets/tarudesu/VOZ-HSD).

Kindly **CITE** our paper if you use ViHateT5-HSD to generate published results or integrate it into other software.

**Example usage**
```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("tarudesu/ViHateT5-base-HSD")
model = AutoModelForSeq2SeqLM.from_pretrained("tarudesu/ViHateT5-base-HSD")

def generate_output(input_text, prefix):
    # Add prefix
    prefixed_input_text = prefix + ': ' + input_text

    # Tokenize input text
    input_ids = tokenizer.encode(prefixed_input_text, return_tensors="pt")

    # Generate output
    output_ids = model.generate(input_ids, max_length=256)

    # Decode the generated output
    output_text = tokenizer.decode(output_ids[0], skip_special_tokens=True)

    return output_text

sample = 'Tôi ghét bạn vl luôn!'
prefix = 'hate-spans-detection' # Choose 1 from 3 prefixes ['hate-speech-detection', 'toxic-speech-detection', 'hate-spans-detection']

result = generate_output(sample, prefix)
print('Result: ', result)
