# Non Factoid Question Category classification in English
## NFQA model

Repository: [https://github.com/Lurunchik/NF-CATS](https://github.com/Lurunchik/NF-CATS)

Model trained with NFQA dataset. Base model is [roberta-base-squad2](https://huggingface.co/deepset/roberta-base-squad2), a RoBERTa-based model for the task of Question Answering, fine-tuned using the SQuAD2.0 dataset.

Uses `NOT-A-QUESTION`, `FACTOID`, `DEBATE`, `EVIDENCE-BASED`, `INSTRUCTION`, `REASON`, `EXPERIENCE`, `COMPARISON` labels.

## How to use NFQA cat with HuggingFace

##### Load NFQA cat and its tokenizer:
```python
from transformers import AutoTokenizer

from nfqa_model import RobertaNFQAClassification 

nfqa_model = RobertaNFQAClassification.from_pretrained("Lurunchik/nf-cats")
nfqa_tokenizer = AutoTokenizer.from_pretrained("deepset/roberta-base-squad2")
```

##### Make prediction using helper function:
```python
def get_nfqa_category_prediction(text):
    output = nfqa_model(**nfqa_tokenizer(text, return_tensors="pt"))
    index = output.logits.argmax()
    return nfqa_model.config.id2label[int(index)]

get_nfqa_category_prediction('how to assign category?')
# result
#'INSTRUCTION'
```

## Demo 
You can test the model via [hugginface space](https://huggingface.co/spaces/Lurunchik/nf-cats).
