# Vietnamese Legal Documents Dataset

## 1. Dataset Summary

**Raw data**: [tmnam20/BKAI-Legal-Retrieval](https://huggingface.co/datasets/tmnam20/BKAI-Legal-Retrieval)

The **Vietnamese Legal Documents Dataset** is a benchmark dataset designed for **legal information retrieval** in the Vietnamese language. It consists of:

- A **corpus** of legal documents.
- **Train/test splits** containing natural language queries and their corresponding relevant documents.

This dataset is intended to support research and development in:

- **Information Retrieval (IR)**
- **Retrieval-Augmented Generation (RAG)**
- **Vietnamese Legal NLP**

---

## 2. Supported Tasks and Use Cases

The dataset can be used for the following tasks:

- **Information Retrieval (IR)**  
  Retrieve relevant legal documents given a natural-language query.

- **Question Answering over Documents**  
  Serve as a retrieval component in QA systems, where retrieved documents are used as grounding context for downstream models (e.g., LLMs).

- **Legal NLP Research**  
  Benchmark and evaluate models in a domain-specific, Vietnamese legal setting.

## 3. Dataset Structure

### 3.1 Corpus

`corpus.parquet`

| column | type   | description                                |
|-------:|:-------|:-------------------------------------------|
| `cid`  | int    | Unique identifier for each document        |
| `text` | string | Full text of a legal document (Vietnamese) |

### 3.2 Train / Test Splits

`train.parquet` / `test.parquet`

| column         | type         | description                                                                 |
|---------------:|:-------------|:----------------------------------------------------------------------------|
| `qid`          | int          | Unique query identifier                                                     |
| `question`     | string       | Natural-language legal query in Vietnamese                                  |
| `cid`          | list<int>    | List of relevant document IDs (subset of `corpus.cid`)                      |
| `context_list` | list<string> | List of text passages mapped from `cid` (aligned by index with `cid` field) |

## 4. **Example Usuage**:

```python
from datasets import load_dataset

ds = load_dataset("YuITC/Vietnamese-Legal-Doc-Retrieval-Data")

print(ds["train"][0])
# {
#   "qid": 72600,
#   "question": "Liên đoàn Luật sư Việt Nam là tổ chức ...",
#   "context_list": ["Điều 2. Địa vị pháp lý của Liên đoàn Luật sư Việt Nam\n1. Liên đoàn Luật sư ..."]
#   "cid": [142820]
# }
```

---

## 5. Limitations

- The dataset does not fully cover the entire Vietnamese legal system.
- Legal texts contain domain-specific terminology, which may be challenging for non-expert users and models.
