+# Vietnamese Legal Documents
+
+A comprehensive dataset of **518,255 Vietnamese legal documents** sourced from
+[thuvienphapluat.vn](https://thuvienphapluat.vn) — the largest Vietnamese legal
+document repository. The dataset covers laws, decrees, circulars, decisions, and
+other official documents issued by Vietnamese government bodies, spanning from
+**1924 to 2026**.
+
+---
+
+## At a Glance
+
+| | |
+|---|---|
+| 🗂️ **Total documents** | 518,255 |
+| 📅 **Date range** | 1924 – 2026 |
+| 🏛️ **Issuing authorities** | 2,393 unique bodies |
+| 📋 **Document types** | 36 unique types |
+| 🌐 **Language** | Vietnamese |
+| 💾 **Content size** | ~3.6 GB (parquet) |
+
+---
+
+## Dataset Structure
+
+This dataset is split into **two configs** to allow fast metadata access without loading the full text.
+
+| Config | Split | Rows | Size | Description |
+|---|---|---|---|---|
+| `metadata` | `data` | 518,255 | ~82 MB | 9 metadata columns, no text content |
+| `content` | `data` | 518,255 | ~3.6 GB | `id` + full markdown document text |
+
+Join on the `id` column to get both metadata and content.
+
+---
+
+## Load the Dataset
+
+```python
+from datasets import load_dataset
+
+# Load metadata only (fast, ~82 MB)
+ds = load_dataset("th1nhng0/vietnamese-legal-documents", "metadata")
+df = ds["data"].to_pandas()
+print(df.head())
+
+# Load full text content (~3.6 GB)
+ds_content = load_dataset("th1nhng0/vietnamese-legal-documents", "content")
+
+# Join metadata + content
+import pandas as pd
+meta = load_dataset("th1nhng0/vietnamese-legal-documents", "metadata")["data"].to_pandas()
+text = load_dataset("th1nhng0/vietnamese-legal-documents", "content")["data"].to_pandas()
+df = meta.merge(text, on="id")
+print(df.columns.tolist())
+```
+
+---
+
+## Schema
+
+### `metadata` config
+
+| Column | Type | Description |
+|---|---|---|
+| `id` | int64 | Unique numeric document ID |
+| `document_number` | string | Official document number (e.g. `115/NQ-HĐBCQG`) |
+| `title` | string | Full Vietnamese title |
+| `url` | string | Source URL on thuvienphapluat.vn |
+| `legal_type` | string | Document type (Quyết định, Công văn, Nghị quyết, …) |
+| `legal_sectors` | string | Pipe-separated sector/topic tags |
+| `issuing_authority` | string | Name of the issuing government body |
+| `issuance_date` | string | Issue date in `DD/MM/YYYY` format |
+| `signers` | string | Pipe-separated `name:id` pairs of signatories |
+
+### `content` config
+
+| Column | Type | Description |
+|---|---|---|
+| `id` | int64 | Document ID — join key with the `metadata` config |
+| `content` | string | Full document text converted to Markdown |
+

+## Use Cases
+
+- 🔍 **Legal information retrieval** — build search engines over Vietnamese law
+- 🤖 **LLM fine-tuning** — train or fine-tune language models on legal Vietnamese
+- 📊 **Legal NLP research** — NER, classification, summarization, QA
+- 📈 **Policy analysis** — track legislative trends over time
+- 🌏 **Low-resource NLP** — Vietnamese legal text is underrepresented in existing datasets

+
+## Data Collection
+
+This is an independent personal research project. Documents were collected from
+[thuvienphapluat.vn](https://thuvienphapluat.vn) — a public legal document portal
+— via their sitemap and mobile API. This project has **no affiliation with
+thuvienphapluat.vn**.
+
+HTML content was converted to Markdown using BeautifulSoup. Only Vietnamese-language
+documents were retained; English versions and technical standards (Tiêu chuẩn) were
+excluded.
+
+---
+
+## License & Legal Basis
+
+Vietnamese legal documents (laws, decrees, circulars, decisions, and other normative
+acts) are **public domain by Vietnamese law**. Under the
+[Law on Access to Information (Luật Tiếp cận thông tin, No. 104/2016/QH13)](https://thuvienphapluat.vn/van-ban/Bo-may-hanh-chinh/Luat-tiep-can-thong-tin-2016-280116.aspx)
+and the [Law on Promulgation of Legal Documents (No. 64/2025/QH15)](https://thuvienphapluat.vn/van-ban/Bo-may-hanh-chinh/Luat-ban-hanh-van-ban-quy-pham-phap-luat-2025-so-64-2025-QH15-639239.aspx),
+official legal normative documents issued by state agencies must be made publicly
+accessible free of charge.
