Vietnamese Legal Documents Dataset

1. Dataset Summary

Raw data: 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	List of relevant document IDs (subset of `corpus.cid`)
`context_list`	list	List of text passages mapped from `cid` (aligned by index with `cid` field)

4. Example Usuage:

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.
