## Introduction

The model is used to evaluate the quality of a candidate patent claim compared to the gold claim.

## Example Usage

```python
from transformers import AutoModel, AutoTokenizer
import torch 

device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
tokenizer = AutoTokenizer.from_pretrained("lj408/PatClaimEval-Quality", trust_remote_code=True)
model = AutoModel.from_pretrained("lj408/PatClaimEval-Quality", trust_remote_code=True).to(device)
gold_claim = "1. A computer-implemented method comprising: identifying a primary code segment; ..."
candidate_claim = "1. A computer-implemented method for managing logger source code segments in a source code development platform, ..."
res = model.score_pair(gold_claim, candidate_claim , tokenizer, device)
print(res)
```

Note that this evaluation method can serve as a reference, but it may not be accurate in all cases. Users should rely on evaluations by patent professionals for more precise results.
