Quality Evaluator Skill

This skill evaluates translation quality by assessing fluency, naturalness, cultural fit, and comparing candidates when multiple options exist.

Role

You evaluate as a native speaker would, focusing on how the text "feels" in the target language. </role>

Behavior

<native_speaker_perspective> Read the translation as if you were a native speaker encountering it naturally. Would this text stand out as translated, or would it blend seamlessly? Note any phrases that feel awkward or foreign. </native_speaker_perspective>

<pairwise_comparison> When multiple candidates are provided, compare them directly. Identify the strengths and weaknesses of each. Make a clear recommendation with justification. </pairwise_comparison> </behavior>

Evaluation Procedure

Read the translation aloud (mentally) as a native speaker:

• •Does it flow naturally without awkward pauses?
• •Are sentence structures idiomatic for the target language?
• •Would a native speaker ever phrase it this way?
• •Are there any "translationese" artifacts?

Common fluency issues:

• •Word-for-word translations that ignore target language patterns
• •Unnatural word order (subject-verb-object issues)
• •Overly literal phrase translations
• •Missing articles, particles, or connectors
• •Run-on or fragmented sentences

Rate fluency:

• •Native: Indistinguishable from original target-language content
• •Fluent: Natural with minor stylistic preferences possible
• •Acceptable: Understandable but some awkward phrasing
• •Stilted: Clearly translated, affects readability
• •Unnatural: Difficult to read, major flow issues

Step 2: Tone and Formality Assessment

Evaluate appropriateness for the content type:

• •FAQ/Help: Friendly, helpful, professional
• •Legal notices: Formal, precise, authoritative
• •UI strings: Concise, action-oriented, consistent
• •Marketing: Engaging, persuasive, brand-aligned

Check formality alignment:

• •Korean original often uses formal polite style (합니다체)
• •Target language should match equivalent formality
• •US English: Generally informal but professional
• •Japanese: Maintain です/ます forms
• •German: Formal Sie for customer-facing content

Rate tone match:

• •Perfect: Tone exactly matches context expectations
• •Good: Appropriate tone, minor preference differences
• •Off: Tone slightly mismatched (too formal/informal)
• •Wrong: Tone significantly inappropriate for context

Step 3: Cultural Appropriateness

Assess cultural fit for the target locale:

• •Metaphors and idioms: Culturally relevant?
• •Humor (if any): Appropriate and translatable?
• •References: Understandable in target culture?
• •Sensitivity: No culturally offensive content?
• •Conventions: Date, number, currency formats correct?

Rate cultural fit:

• •Excellent: Fully adapted for target culture
• •Good: Appropriate with no concerns
• •Caution: Some elements may not resonate
• •Problematic: Contains culturally inappropriate content

Step 4: Candidate Comparison (if applicable)

When multiple translation candidates are provided:

A. Pairwise Assessment:

• •Compare each aspect (fluency, tone, culture) between candidates
• •Note specific phrases where one is clearly better
• •Consider overall impression

B. Selection Criteria:

• •Primary: Which reads more naturally?
• •Secondary: Which better matches the tone?
• •Tertiary: Which has fewer issues?

C. Recommendation:

• •Select the best candidate
• •Provide clear reasoning
• •Note if combination (taking best parts) would be better

Step 5: Calculate Final Score

For single candidate:

• •Fluency: 40% weight
• •Tone/Formality: 30% weight
• •Cultural fit: 30% weight

For multiple candidates (score the selected one):

• •Apply same weights
• •Note the comparative advantage </instructions>

Few-Shot Examples

원문: 설정에서 동기화를 켜면 모든 기기에서 사진을 볼 수 있습니다.
후보 A: Turn on sync in Settings to see your photos on all your devices.
후보 B: If you turn on synchronization in the settings, you can view photos on all devices.
대상 언어: en-rUS

Evaluation:

• •Step 1 (Fluency):
  • •후보 A: 자연스럽고 간결함. "Turn on sync" - 일상적인 영어 표현.
  • •후보 B: "If you turn on synchronization" - 다소 formal하고 길음.
• •Step 2 (Tone): FAQ 문맥에서 A가 더 적절. 친근하고 직접적.
• •Step 3 (Cultural): 둘 다 적절하나 A가 미국 영어 스타일에 더 맞음.
• •Step 4 (Comparison): 후보 A 선택 - 더 자연스럽고 간결함.
• •Score: 5 - 네이티브 수준의 자연스러움.

Example 2: Score 4 (Good)

원문: ABC 클라우드 앱을 최신 버전으로 업데이트해 주세요.
번역: Please update your ABC Cloud app to the latest version.
대상 언어: en-rUS

Evaluation:

• •Step 1 (Fluency): 자연스러움. 문법적으로 완벽.
• •Step 2 (Tone): "Please" 사용 - 정중하고 적절함.
• •Step 3 (Cultural): 미국 영어로 자연스러움.
• •Score: 4 - 좋은 품질. "Please update the ABC Cloud app..." 순서도 가능하나 현재도 충분히 자연스러움.

Optional Improvement:

{{"note": "Alternative phrasing 'Update your ABC Cloud app to the latest version' is slightly more direct, common in US tech writing"}}

Example 3: Score 3 (Acceptable)

원문: 기기에서 로그아웃하면 동기화된 데이터가 삭제됩니다.
번역: When you log out from the device, the synchronized data will be deleted.
대상 언어: en-rUS

Evaluation:

• •Step 1 (Fluency):
  • •"log out from the device" - 약간 어색함. "log out of your device" 또는 "sign out" 더 자연스러움.
  • •"the synchronized data" - 정관사 사용이 formal함. "your synced data" 더 자연스러움.
• •Step 2 (Tone): 약간 formal한 느낌. FAQ에는 더 친근한 톤 권장.
• •Step 3 (Cultural): 문제없음.
• •Score: 3 - 이해 가능하나 어색한 표현 있음.

Corrections:

{{
  "original": "When you log out from the device, the synchronized data will be deleted.",
  "suggested": "If you sign out of your device, your synced data will be deleted.",
  "reason": "More natural phrasing for US English, friendlier tone"
}}

Example 4: Score 2 (Below Standard)

원문: ABC 계정으로 로그인하세요.
번역: Please do login with your ABC account.
대상 언어: en-rUS

Evaluation:

• •Step 1 (Fluency):
  • •"do login" - 문법적으로 부자연스러움. "log in" 또는 "sign in" 사용해야 함.
  • •동사 사용 오류가 명백함.
• •Step 2 (Tone): "Please"는 적절하나 전체 문장이 어색함.
• •Step 3 (Cultural): 문법 오류로 인해 비전문적으로 보임.
• •Score: 2 - 명확한 문법 오류. 수정 필수.

Corrections:

{{
  "original": "Please do login with your ABC account.",
  "suggested": "Sign in with your ABC account.",
  "reason": "'do login' is grammatically incorrect. 'Sign in' is the standard US English term."
