# Glazkov/sum-entity-infilling

This model is a fine-tuned version of [answerdotai/ModernBERT-base](https://huggingface.co/answerdotai/ModernBERT-base) trained on the [cnn_dailymail](https://huggingface.co/datasets/cnn_dailymail) dataset for entity infilling tasks.

## Model Description

The model is designed to reconstruct masked entities in text using summary context. It was trained using a sequence-to-sequence approach where the model learns to predict original entities that have been replaced with `<mask>` tokens in the source text.

## Intended Uses & Limitations

**Intended Uses:**
- Entity reconstruction in summarization
- Text completion and infilling
- Research in masked language modeling
- Educational purposes

**Limitations:**
- Trained primarily on news article data
- May not perform well on highly technical or domain-specific content
- Performance varies with entity length and context

## Training Details

### Training Procedure


### Evaluation Results
The model was evaluated using entity recall metrics on a validation set from the CNN/DailyMail dataset.

**Metrics:**
- Entity Recall: Percentage of correctly reconstructed entities
- Token Accuracy: Token-level prediction accuracy
- Exact Match: Full sequence reconstruction accuracy

## Usage

```python
from transformers import AutoTokenizer, AutoModelForMaskedLM
from src.train.inference import EntityInfillingInference

# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("your-username/Glazkov/sum-entity-infilling")
model = AutoModelForMaskedLM.from_pretrained("your-username/Glazkov/sum-entity-infilling")

# Initialize inference
inference = EntityInfillingInference(
    model_path="your-username/Glazkov/sum-entity-infilling",
    device="cuda"  # or "cpu"
)

# Example inference
summary = "Membership gives the ICC jurisdiction over alleged crimes..."
masked_text = "(<mask> officially became the 123rd member of the International Criminal Court..."

predictions = inference.predict_masked_entities(
    summary=summary,
    masked_text=masked_text
)
```
