What it probes

KUEST targets phenomena where fluent MT output can still be wrong for Korean in the game domain. It groups items into four categories:

Category	Items	Focus
TA — Terminology & Accuracy	331	Glossary canonical compliance; polysemy disambiguation by context
PP — Persona & Pragmatics	472	Speech-register/honorific consistency by speaker persona; dual-prompt (baseline vs. persona-enriched regime R)
TR — Translation Robustness	507	Placeholder reordering, tag preservation, length constraints
CT — Cultural Transcreation	570	Honorifics, onomatopoeia, idioms, naming, hate speech, etc.

Items are ordered TA → PP → TR → CT.

PP dual-prompt (regime R)

PP now ships the same 236 speaker utterances under two prompt regimes so the effect of persona context on the translation can be measured:

• baseline — the fixed prompt Translate from en to ko_KR. (subcategories PP-persona_pragmatics, PP-ambiguous; 236 rows).
• regime R — an English prompt enriched with speaker persona/relationship facts (speaker name, role tier, in-game unit type, speech act, and social-standing relationship), without prescribing Korean endings (subcategories PP-persona_pragmatics-regime_r-001-a … -097-b and PP-ambiguous-regime_r-001-a … -021-b; 236 rows).

Record format

Every line contains exactly the seven WMT fields:

{"dataset_id": "KUEST", "doc_id": "en-ko_KR_#_KUEST_#_CT-idiom_proverb-001", "src_lang": "en", "tgt_lang": "ko_KR", "prompt": "Translate from en to ko_KR.", "src_text": "Your skill in speaking to other people. Covers ability in boasting, flattery, threats, persuasion, lies, and other facets of interpersonal communication. Works best in conjunction with a high level of intelligence.", "ref_text": "사람들과 대화하는 기술입니다. 자랑, 아첨, 위협, 설득, 거짓말 등 사람들과의 소통 전반에 영향을 미칩니다. 지능이 높은 캐릭터와 결합하면 금상첨화일 것입니다."}

• doc_id pattern: en-ko_KR_#_KUEST_#_<category>-<subcategory>-<NNN>; numbering restarts at 001 per subcategory (3-digit zero-pad). The PP category splits each speaker pair into two rows with -a / -b suffixes; the regime R rows reuse the source subcategory stem with a -regime_r- infix (PP-persona_pragmatics-regime_r-…, PP-ambiguous-regime_r-…), keeping the source split and the original pair numbering.
• prompt is fixed (Translate from en to ko_KR.) for every row except the 236 regime R rows (the *-regime_r-* subcategories), which carry persona-enriched prompts (see PP dual-prompt above).
• ref_text holds the Korean reference (never null in this suite); it is identical across both PP regimes.

Text normalization

• Paragraph/line breaks are encoded as \n\n (per the WMT format note).
• Tabs and other control characters are replaced with a single space.
• Placeholders and tags (%s, {n}, <span ...>, $player_…) are preserved; source↔reference placeholder parity was verified for all TR items.

KUEST — Dataset Licensing

KUEST is distributed as a single data file, KUEST.jsonl. Its items are derived from open-source game-localization data released under two different, mutually incompatible copyleft licenses (GPL-2.0 and CC BY-SA 3.0). KUEST.jsonl is therefore not under a single license: it is a collection in which each record is independently licensed according to its license field.

Even though the data itself is one file, a compliant release must also ship this notice and copies of the two license texts — see "Redistribution & compliance".

Component licenses

Upstream source	Records	License (SPDX)	Upstream repository
CDDA(Cataclysm-DDA)	855	CC-BY-SA-3.0	https://github.com/CleverRaven/Cataclysm-DDA
Wesnoth(Battle for Wesnoth)	941	GPL-2.0	https://github.com/wesnoth/wesnoth
Total	1796	(mixed collection)

Each record in KUEST.jsonl carries:

• source — the upstream project the record's text is derived from.
• license — the SPDX identifier governing that record's src_text and ref_text.

Filter by the license field to obtain a single-license subset.

Compilation

The selection, structuring, and original fields authored by the KUEST authors (e.g., the doc_id scheme and prompt field) are offered under CC-BY-4.0. This applies only to the KUEST authors' original material and does not relicense the src_text/ref_text, which remain under their component licenses above. Where upstream text was modified (e.g., the gender-neutral reference corrections), the modified text is a derivative of the copyleft source and stays under that source's license (CC-BY-SA-3.0).

Redistribution & compliance

If you redistribute KUEST.jsonl or a derivative:

• Keep each record under its component license (the license field). Do not relicense the whole file under a single or permissive license.
• Ship the license texts. Include this notice and verbatim copies of the CC BY-SA 3.0 and GPL-2.0 license texts alongside the data (e.g., in licenses/). Both licenses require the license to accompany the work; GPL requires including a copy of its text.
• Preserve attribution to both upstream projects.
• ShareAlike / copyleft. Distribute any adaptation of a record under the same (or a compatible) license as that record.
• GPL source form. For the Battle for Wesnoth records, the text itself is the corresponding source form, provided under GPL-2.0-or-later.

More conservative option. The single mixed file is a labeled collection and is defensible, but if you want the airtight "separable aggregation" posture, split the data by license into two files — e.g., KUEST-cdda.jsonl (CC-BY-SA-3.0) and KUEST-wesnoth.jsonl (GPL-2.0-or-later) — instead of one mixed file. This removes any ambiguity about whether the file is a single combined work.

Note

This is a mere-aggregation collection: records under different licenses are bundled together, but each remains independently licensed via its license field. This document is not legal advice — verify license compatibility and your redistribution obligations with your institution before public release.
