# RoBERTa Large for MIT Restaurant NER

This model is a fine-tuned version of RoBERTa Large on the MIT Restaurant dataset for Named Entity Recognition (NER).

## Model Description

- **Model type:** Token Classification (NER)
- **Base model:** roberta-large
- **Dataset:** MIT Restaurant NER dataset
- **Languages:** English
- **Task:** Named Entity Recognition for restaurant domain

## Entity Types

The model can identify the following entity types:
['O', 'B-Amenity', 'I-Amenity', 'B-Cuisine', 'I-Cuisine', 'B-Dish', 'I-Dish', 'B-Hours', 'I-Hours', 'B-Location', 'I-Location', 'B-Price', 'I-Price', 'B-Rating', 'I-Rating', 'B-Restaurant_Name', 'I-Restaurant_Name']

## Usage

```python
from transformers import AutoTokenizer, AutoModelForTokenClassification, pipeline

tokenizer = AutoTokenizer.from_pretrained("niruthiha/roberta-large-mit-restaurant-ner")
model = AutoModelForTokenClassification.from_pretrained("niruthiha/roberta-large-mit-restaurant-ner")

# Using pipeline
nlp = pipeline("ner", model=model, tokenizer=tokenizer, aggregation_strategy="simple")
result = nlp("I want a reservation at an italian restaurant with outdoor seating")
print(result)

# Manual usage
inputs = tokenizer("I want a reservation at an italian restaurant", return_tensors="pt")
outputs = model(**inputs)
```
