# Email Processing ModernBERT Model

Fine-tuned ModernBERT model for email processing tasks.

## Model Capabilities

This model can compute semantic similarity between questions and answers related to:
- Email addresses
- Subject lines

## Recommended Thresholds

Based on extensive testing, the following thresholds are recommended:

- For email questions: 0.85
- For subject questions: 0.70
- For other questions: 0.80

Additional content-aware checks are recommended for best results.

## Usage

```python
from sentence_transformers import SentenceTransformer
import torch

# Load the model
model = SentenceTransformer('sugiv/email-processing-modernbert')

# Encode questions and answers
q_embed = model.encode("What's your email address?", convert_to_tensor=True)
a1_embed = model.encode("My email is user@example.com", convert_to_tensor=True)
a2_embed = model.encode("The weather is nice today", convert_to_tensor=True)

# Calculate similarity
similarity1 = torch.nn.functional.cosine_similarity(q_embed.unsqueeze(0), a1_embed.unsqueeze(0)).item()
similarity2 = torch.nn.functional.cosine_similarity(q_embed.unsqueeze(0), a2_embed.unsqueeze(0)).item()

print(f'Similarity with relevant answer: {similarity1:.4f}')
print(f'Similarity with irrelevant answer: {similarity2:.4f}')

# Apply threshold
threshold = 0.85  # For email questions
print(f'Is relevant: {similarity1 >= threshold}')
print(f'Is irrelevant: {similarity2 < threshold}')
```
