## Usage
```python

# update tokenizer with special tokens
INTENT_CLASSES = ['none', 'clarity', 'fluency', 'coherence', 'style', 'meaning-changed']  # `meaning-changed` is not used
INTENT_OPENED_TAGS = [f'<{intent_class}>' for intent_class in INTENT_CLASSES]
INTENT_CLOSED_TAGS = [f'</{intent_class}>' for intent_class in INTENT_CLASSES]
INTENT_TAGS = set(INTENT_OPENED_TAGS + INTENT_CLOSED_TAGS)
special_tokens_dict = {'additional_special_tokens': ['<bos>', '<eos>'] + list(INTENT_TAGS)}
tokenizer.add_special_tokens(special_tokens_dict)
