# Minecraft NL→Command Dataset (Japanese / English)
自然言語の指示(日本語・英語)を Minecraft Java Edition **1.21.5** のコマンドに変換するためのデータセットです。
A dataset of natural-language instructions (Japanese / English) paired with Minecraft Java Edition **1.21.5** commands.
```json
{"instruction": "自分の持っているアイテムにウィンドバーストIを付与して",
"output": "/enchant @s minecraft:wind_burst 1",
"lang": "ja", "command": "enchant", "mc_version": "1.21.5"}
```
## Contents
- **~51k pairs** (train ≈ 48.5k / test ≈ 2.5k), roughly half Japanese, half English
- **12 commands**: `give` (plain / count / enchanted with 1.21+ item components), `effect give`
(simple / timed+amplifier / infinite), `summon`, `enchant`, `tp`, `time set`, `weather`,
`gamemode`, `setblock`, `fill`, `clear`, `xp`
- Item / block / entity / effect / enchantment names use **Mojang's official ja_jp / en_us translations**,
so surface forms match what players actually see in-game
- Enchanted `give` uses the modern **item component syntax**
(`[minecraft:enchantments={"minecraft:sharpness":5}]`, 1.21.2+ format) with only
category-compatible enchantments and vanilla-legal levels
- Ambiguous display names (e.g. every music disc is just "Music Disc") are **excluded** so each
instruction maps to exactly one command
## Fields
| field | description |
|---|---|
| `instruction` | natural-language request (ja or en) |
| `output` | the corresponding slash command |
| `lang` | `ja` / `en` |
| `command` | base command name (e.g. `give`) |
| `mc_version` | targeted Minecraft version (`1.21.5`) |
## How it was built
Fully deterministic template-based generation (no LLM involved):
official Mojang registry data + official translation files + hand-written sentence templates
(seeded RNG, deduplicated, 95/5 split). Generation code: see the `generate.py` in the source repository.
## Quality assurance
Every release passes a three-layer validation pipeline:
1. **Syntax layer (100% of records)** — each command is matched against a strict per-command grammar,
every ID is checked against the official 1.21.5 registries, and numeric arguments are range-checked
(vanilla enchantment level caps, `/fill` volume limit, tick range, etc.).
2. **Round-trip layer (100% of records)** — slots are re-extracted from the command and matched back
against the instruction: item/entity/effect names, counts, durations, coordinates, Roman-numeral
levels, and selector↔phrase correspondence (`@a` ⇔ "everyone"/「全員」).
3. **LLM-judge layer (stratified)** — a local LLM judges semantic faithfulness and native-speaker
naturalness on samples stratified per (language × template), so every template that produced records
is audited. Templates flagged across four review rounds were rewritten and the dataset regenerated.
Final result for this release: layers 1–2 pass 51,089/51,089; layer 3 certifies 114/115 template
groups. The single remaining flag is a verified judge false positive (`/summon minecraft:tnt` does
spawn primed TNT, matching the official Japanese name 「着火されたTNT」).
## Limitations
- Sentence variety is template-bound (a few phrasings per command type); not a substitute for
human-written requests.
- Commands are validated against the 1.21.5 grammar and registries but were not executed in-game.
- `enchant` pairs assume the held item is compatible; the command itself is well-formed regardless.
