📜 NitiBench-Statute: Thai Legal Corpus for RAG

Part of the NitiBench Project

This dataset contains the complete corpus of legal sections used in the NitiBench benchmark (CCL and Tax subset). It comprises 5,127 legal sections extracted from 35 Thai legislations (primarily focusing on Corporate and Commercial Law).

It is designed to be used as a Context Pool (Knowledge Base) for Retrieval-Augmented Generation (RAG) pipelines. Researchers and developers can load this dataset to populate vector databases or search indices to reproduce NitiBench baselines or evaluate new retrieval strategies.

🚀 Quick Start

Loading the Dataset

You can easily load this dataset using the Hugging Face datasets library:

from datasets import load_dataset

# Load the statute corpus
dataset = load_dataset("vistec-AI/nitibench-statute", split="ccl")

# Example: Print the first section
print(dataset[0])

Usage for RAG (Context Pool)

To use this as a retrieval source, you typically iterate through the section_content to create embeddings:

documents = []
ids = []

for row in dataset:
    # Use 'section_content' as the text chunk to be indexed
    documents.append(row['section_content'])
    # Use 'law_code' or a combination of name+section as ID
    ids.append(f"row['law_code']-row['section_num']")

# ... Proceed to pass `documents` to your VectorDB or Retriever (e.g., FAISS, ChromaDB, BM25)

📊 Dataset Statistics

Total Documents: 5,127 sections
Total Legislations: 35 Legislation (Corporate and Commercial Law)
Language: Thai

📂 Data Structure

Each row represents a specific section of a law.

Column Name	Type	Description
`law_code`	`str`	Unique identifier for the specific law section (e.g., `ก0123-1B-0001`).
`law_name`	`str`	The official full name of the legislation (e.g., `พระราชบัญญัติการประกอบกิจการพลังงาน พ.ศ. 2550`).
`section_num`	`str`	The specific section number within the Act (e.g., `26`).
`section_content`	`str`	The full text content to be used for retrieval. This includes the law name, section number, and the provision text combined.
`reference`	`list`	A list of cross-references to other laws (if applicable).
