+# Danbooru 2026 Tag Cleaning Corrections
+
+This dataset contains image-level tag corrections for an anime-image tagging
+corpus. It contains correction instructions only; it does not contain images,
+captions, or the original sidecar metadata.
+
+## Schema
+
+| Column | Type | Description |
+|---|---|---|
+| `image_id` | string | Danbooru post ID, or a generated-sample identifier |
+| `add` | list[string] | Tags to add |
+| `remove` | list[string] | Tags to remove |
+| `updated_at` | string | Original correction timestamp in ISO-8601 format |
+
+Tag values use the prefixes from the reference sidecars:
+
+- `gen:` — general
+- `char:` — character
+- `copyright:` — copyright/series
+- `artist:` — artist
+- `meta:` — metadata
+
+For example, `gen:holding_toothbrush` is a general tag.
+
+## Dataset statistics
+
+- 1,739,622 correction rows
+- 1,915,583 add actions
+- 474,953 remove actions
+- 9,363 unique source tags examined
+- 301 dead or unmapped source tags removed
+- 39,371 rows with no remaining actions removed
+
+## Normalization
+
+The corrections were normalized against a Danbooru metadata snapshot taken on
+2026-08-30. Active tag aliases were resolved to canonical names, explicit
+wiki-documented splits were expanded when available, and tags with no current
+record or no active replacement were removed. Additional data cleaning was
+applied to the correction fields, and rows with no remaining actions were
+omitted. No fuzzy tag-name guesses were used.
+
+The normalization used 1 serialized API request at a minimum interval of one
+second, reusing cached responses for the remaining tag records. The original
+`merged.json` and the original image sidecars were not modified.
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("Grio43/Tag_cleaning", split="train")
+print(dataset[0])
+```
+
+## Limitations
+
+This is a correction manifest, not a fully relabeled image dataset. Applying
+the corrections requires access to the corresponding image metadata. The
+corrections reflect the source cleaning process and should be reviewed before
+being used as ground truth.
+
+## Source and audit
+
+The source manifest was `merged.json`. The local normalized release was
+validated for JSON/Parquet row parity before publication. The Danbooru site and
+its tag documentation are available at <https://danbooru.donmai.us>.
