# Dataset Card for French Legal Cases Dataset

## Dataset Description

- **Homepage:** [https://huggingface.co./datasets/la-mousse/combined-fe-caselaw](https://huggingface.co./datasets/la-mousse/combined-fe-caselaw)
- **Repository:** [https://huggingface.co./datasets/la-mousse/combined-fe-caselaw](https://huggingface.co./datasets/la-mousse/combined-fe-caselaw)
- **Paper:** N/A
- **Point of Contact:** [Your Contact Information]

### Dataset Summary

This dataset combines French legal cases from multiple sources (INCA, JADE, CASS, CAPP) into a unified format with overlapping text triplets. It includes decisions from various French courts, processed to facilitate natural language processing tasks.

### Supported Tasks and Leaderboards

- **Tasks:**
  - Text Generation
  - Legal Document Analysis
  - Text Classification
  - Language Modeling

### Languages

The dataset is monolingual (French).

## Dataset Structure

### Data Instances

Each instance contains:
- Document identifiers (id, url, case_number)
- Original text content (contenu)
- Summaries (sommaire, sommaire_bis)
- Metadata (JSON formatted string)
- Text triplets (previous_text, current_text, next_text)
- Position tracking (triplet_index, window_index)

Example:
```python
{
    'id': 'CASS12345',
    'url': 'https://...',
    'case_number': '12-34567',
    'contenu': 'Full text...',
    'sommaire': 'Summary...',
    'sommaire_bis': 'Additional summary...',
    'metadata': '{"date_decision": "2023-01-01", ...}',
    'dataset_source': 'CASS',
    'previous_text': 'Previous chunk...',
    'current_text': 'Current chunk...',
    'next_text': 'Next chunk...',
    'triplet_index': 0,
    'window_index': 0
}
```

### Data Fields

- `id`: Unique identifier
- `url`: Source URL
- `case_number`: Case reference number
- `contenu`: Full text content
- `sommaire`: Primary summary
- `sommaire_bis`: Secondary summary
- `metadata`: JSON string containing additional metadata
- `dataset_source`: Origin dataset (INCA/JADE/CASS/CAPP)
- `previous_text`: Previous text chunk
- `current_text`: Current text chunk
- `next_text`: Next text chunk
- `triplet_index`: Position in sequence of triplets
- `window_index`: Window number for long texts

### Data Splits

- Training split only

## Dataset Creation

### Curation Rationale

This dataset was created to provide a standardized format for French legal texts, with overlapping text chunks suitable for various NLP tasks.

### Source Data

#### Initial Data Collection and Normalization

- INCA: Court of Cassation decisions
- JADE: Administrative court decisions
- CASS: Court of Cassation decisions
- CAPP: Court of Appeal decisions

### Preprocessing

- Text chunking with 230-token chunks and 30-token overlap
- Sliding window approach for long texts
- Metadata preservation and standardization
- Token count verification
- JSON formatting for metadata

### Quality Control

- Token length verification
- Chunk coherence checks
- Metadata validation
- Error logging and handling

## Considerations for Using the Data

### Social Impact of Dataset

This dataset aims to improve access to and understanding of French legal decisions, potentially benefiting legal research and analysis.

### Discussion of Biases

The dataset may reflect inherent biases in the French legal system and case selection/publication processes.

### Other Known Limitations

- Limited to published decisions
- Varying detail levels across sources
- Potential OCR errors in source texts
