|
| 136 |
-
| `detail_url` / `pdf_url` | string | Deep link back to the portal page / PDF. |
|
| 137 |

| `doc_code` | string | E.g. `38/2021/DS-PT` (sequence/year/case-type-procedure). |
|
| 138 |
-
| `doc_type` | string | Structure-layer form of the underlying document. Full taxonomy: `ban_an` \| `quyet_dinh` \| `an_le` \| `ban_cao_trang`; **in this corpus only `ban_an` (1,139), `quyet_dinh` (698) and `null` (7) occur** — the adopted precedents themselves are flagged via `precedent_number`, not `doc_type`. |

|
| 147 |
-
| `jurisdiction` | string | **Deprecated — do not use for legal analysis; scheduled for removal in the next schema revision.** Locality token substring-parsed out of `issuing_authority` (the token after the most-specific `huyện`/`quận`/`thị xã`/`tỉnh`/`thành phố` marker in the court name). It records the court's *seat*, **not** its territorial jurisdiction (*thẩm quyền theo lãnh thổ*) — e.g. the High Court seated in Ho Chi Minh City hears appeals from the whole southern region. 100% re-derivable from `issuing_authority`; ~65% `null` (letterheads like `TÒA ÁN NHÂN DÂN CẤP CAO TẠI ĐÀ NẴNG` carry no marker); district values lack their province; OCR noise passes through verbatim. Prefer `issuing_authority` + `court_level`. |

Mỗi điểm là một văn bản; toạ độ là vector embedding 4096-D từ `nvidia/Nemotron-3-Embed-8B-BF16` chiếu xuống 2D bằng UMAP, cụm bằng HDBSCAN. Mỗi hình một hàng. — Each dot is one document; coordinates are the 2D UMAP projection of a 4096-D embedding from `nvidia/Nemotron-3-Embed-8B-BF16`, with HDBSCAN cluster ids. One figure per row.

**Classification** — `category` · `instance_level` · `court` (VI court name) · `court_level` (English tier) · `issued_date` (date) · `date_source`.

**Precedent** — `precedent_number` (e.g. `44/2021/AL`, non-null on the 9 official án lệ) · `is_precedent` (bool).
|
| 132 |
|
| 133 |

**Citations** — first-class `list<struct>`:

| Column | Struct fields |
|

| `citations_law` (29,783) | `kind` (`provision`\|`document`) · **`ref`** (VI, ordered large→small `Chương→Mục→Điều→Khoản→Điểm` + law + `năm`) · `chapter`,`section`,`article`,`clause`,`point` · `law_type`,`law_name` (VI) · `id`,`year` · **`sentence_id`** (grounding → `sentences`) · **`span`** (char offsets `[[start,end],…]` into `markdown`) |

Plus `citations_source` (`llm` \| `llm+section` \| `regex`), `num_law_citations`, `num_case_citations`. **79% of law citations carry a `sentence_id` + `span`** (anchored on `Điều <article>`; the rest are normative-by-number ids not found verbatim).

Quick load:

|
| 146 |
```python
|
|
|
|
| 147 |
from datasets import load_dataset
|
| 148 |
|
| 149 |
+
docs = load_dataset("tmquan/anle-toaan-gov-vn", split="train") # documents config

## Companion configs · `sentences` + `embed` + `reduce`
|
| 157 |
|
| 158 |
+
Three parquet bundles accompany `documents`; all join on the `doc_name` primary key, and `sentences` also links to citations via `sentence_id`.
|
| 159 |
|
| 160 |
+
### `sentences-*.parquet` — sentence-level rows (169,698)
|
| 161 |
|
| 162 |
+
Sentence-split from the shipped `markdown` (conservative Vietnamese-legal splitter); `char_start`/`char_end` index the *same* `markdown`, so `citations_*.span` and `citations_*.sentence_id` line up exactly.
|
| 163 |
|
| 164 |
| Field | Type | Description |
|
| 165 |
|---|---|---|
|
| 166 |
+
| `sentence_id` | string | `{doc_name}#{sent_idx}` — the grounding id referenced by `citations_*.sentence_id`. |
|
| 167 |
+
| `doc_name` | string | Join key back to `documents`. |
|
| 168 |
+
| `sent_idx` | int | Sentence index within the document. |
|
| 169 |
+
| `char_start` / `char_end` | int | Char span into the parent `documents.markdown`. |
|
| 170 |
+
| `text` | string | The sentence. |
|
| 171 |
+
| `category` / `instance_level` / `year` / `precedent_number` | string / int | Parent-document facets (promoted for slicing without a join). |

### `embed-*.parquet` — dense vectors (1,844)
|
| 181 |
|
| 182 |

`nvidia/Nemotron-3-Embed-8B-BF16` (**4096-d**, "Nemotron-3" = v3), **`chunking=sentence`** (sentence-boundary sliding windows + mean-pool), run in-process on a GB10.

Mỗi luồng là một trích dẫn pháp luật: bắt đầu từ *lĩnh vực · cấp xét xử* của bản án, đi qua *tài liệu* (toàn bộ 1.844 bản án), tới *điều khoản được viện dẫn* (`Điều → Khoản → Điểm`, kể cả `Chương/Mục`). Màu luồng theo lĩnh vực·cấp. — Each flow is one law-citation: from the judgment's *legal category · court level*, through the *document* (all 1,844 judgments), to the *cited provision* (`Điều → Khoản → Điểm`, incl. `Chương/Mục`). Links are coloured by category·subcategory.

Mỗi điểm là một văn bản; toạ độ là vector embedding 4096-D từ `nvidia/Nemotron-3-Embed-8B-BF16` chiếu xuống 2D bằng **t-SNE** và **UMAP**. Toạ độ PCA/t-SNE/UMAP đều lưu trong `reduce-*.parquet`. — Each dot is one document; coordinates are the 2D **t-SNE** and **UMAP** projections of a 4096-D `nvidia/Nemotron-3-Embed-8B-BF16` embedding. PCA/t-SNE/UMAP coordinates all ship in `reduce-*.parquet`.
