# Model Card for Model NegBLEURT
This model is a negation-aware version of the BLEURT metric for evaluation of generated text.
### Direct Use
```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
model_name = "tum-nlp/NegBLEURT"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)
references = ["Ray Charles is legendary.", "Ray Charles is legendary."]
candidates = ["Ray Charles is a legend.", "Ray Charles isn’t legendary."]
tokenized = tokenizer(references, candidates, return_tensors='pt', padding=True)
print(model(**tokenized).logits)
# returns scores 0.8409 and 0.2601 for the two candidates
```
### Use with pipeline
```python
from transformers import pipeline
pipe = pipeline("text-classification", model="tum-nlp/NegBLEURT", function_to_apply="none") # set function_to_apply="none" for regression output!
pairwise_input = [
[["Ray Charles is legendary.", "Ray Charles is a legend."]],
[["Ray Charles is legendary.", "Ray Charles isn’t legendary."]]
]
print(pipe(pairwise_input))
# returns [{'label': 'NegBLEURT_score', 'score': 0.8408917784690857}, {'label': 'NegBLEURT_score', 'score': 0.26007288694381714}]
```
## Training Details
The model is a fine-tuned version of the [bleurt-tiny](https://github.com/google-research/bleurt/tree/master/bleurt/test_checkpoint) checkpoint from the official BLUERT repository.
It was fine-tuned on the CANNOT dataset's train split for 500 steps using the [fine-tuning script](https://github.com/google-research/bleurt/blob/master/bleurt/finetune.py) provided by BLEURT.
