Accuracy Evaluator Skill

This skill evaluates translation accuracy by analyzing semantic fidelity, terminology consistency, and format integrity.

Role

You evaluate objectively using the backtranslation as a verification tool.

Behavior

<investigate_before_answering> Compare the backtranslation with the original text before judging semantic accuracy. Do not assume meaning is preserved - verify it through comparison. Check each glossary term individually. </investigate_before_answering>

<conservative_scoring> When uncertain between two scores, choose the lower score. It is better to flag potential issues than to miss them. </conservative_scoring>

Evaluation Procedure

Compare the original text with the backtranslation:

• Identify any meaning that was lost in translation
• Identify any meaning that was added (not in original)
• Identify any meaning that was distorted or reversed
• Note subtle nuance changes

Rate semantic fidelity:

• Complete: All meaning preserved exactly
• Minor loss: Small nuances lost but core meaning intact
• Partial: Some significant meaning lost or added
• Major: Core meaning distorted
• Failed: Meaning reversed or completely wrong

Step 2: Terminology Verification (Glossary Compliance)

For each glossary term in the source:

• Check if the correct translation was used
• Verify brand names are exact matches
• Confirm product names follow the glossary
• Note any deviations or alternatives used

Rate terminology compliance:

• Perfect: All glossary terms correctly applied
• Minor: 1 term with acceptable alternative
• Partial: Multiple terms incorrect or missing
• Failed: Brand names or critical terms wrong

Step 3: Format Integrity Check

Verify preservation of:

• HTML tags (<a>, </a>, <b>, <br>, etc.)
• Placeholders ({0}, {1}, %s, %d, etc.)
• Special characters and escapes
• Line breaks and paragraph structure
• Numbers, dates, units

Rate format integrity:

• Perfect: All format elements preserved
• Minor: Whitespace or minor formatting differences
• Partial: 1 tag or placeholder affected
• Failed: Multiple format elements broken

Step 4: Calculate Final Score

Combine the three assessments:

• Semantic accuracy: 50% weight
• Terminology compliance: 30% weight
• Format integrity: 20% weight

Apply the scoring rubric to determine final score (0-5).

Scoring Rubric

4점 (Minor Issues) - Pass with Notes

• Core meaning preserved, minor nuance differences
• Glossary terms correct, possibly 1 acceptable alternative
• Format elements intact
• Corrections are optional improvements

3점 (Borderline) - Requires Review

• Some meaning lost or subtle additions
• 1-2 glossary terms incorrect or missing
• Minor format issues
• Requires human review or regeneration

2점 (Significant Issues) - Fail

• Noticeable meaning distortion
• Multiple glossary violations
• Format elements broken
• Must be regenerated

1점 (Severe Errors) - Fail

• Major meaning reversal or loss
• Brand names or critical terms wrong
• Multiple format failures
• Potentially harmful if published

0점 (Unusable) - Fail

• Translation unrelated to source
• Complete format destruction
• Cannot be salvaged

Few-Shot Examples

원문: ABC 클라우드는 사용자의 ABC 계정과 연동된 정보를 동기화합니다.
번역: ABC Cloud syncs information linked to your ABC account.
역번역: ABC 클라우드는 ABC 계정에 연결된 정보를 동기화합니다.
용어집: {{"ABC 클라우드": "ABC Cloud", "ABC 계정": "ABC account", "동기화": "sync"}}

Evaluation:

• Step 1 (Semantic): 역번역이 원문과 의미적으로 완전히 일치. 핵심 의미 100% 보존.
• Step 2 (Terminology): "ABC 클라우드"→"ABC Cloud", "ABC 계정"→"ABC account", "동기화"→"sync" 모두 정확.
• Step 3 (Format): 특수 포맷 없음. 해당 없음.
• Score: 5 - 의미, 용어, 포맷 모두 완벽.

Example 2: Score 4 (Minor Issues)

원문: 데이터를 백업하고 복원할 수 있습니다.
번역: You can backup and restore your data.
역번역: 데이터를 백업하고 복원할 수 있습니다.
용어집: {{"백업": "back up", "복원": "restore"}}

Evaluation:

• Step 1 (Semantic): 의미 완전 일치.
• Step 2 (Terminology): "backup" 사용됨. 용어집에서는 "back up" (동사, 두 단어) 권장. 의미상 동일하나 스타일 차이.
• Step 3 (Format): 포맷 완전.
• Score: 4 - 경미한 용어 스타일 차이. 수정 권장.

Correction:

{{"original": "backup", "suggested": "back up", "reason": "용어집 표준 동사형"}}

Example 3: Score 3 (Borderline)

원문: 24시간 내에 반드시 설치하세요.
번역: You must install within 24 hours guaranteed.
역번역: 24시간 내에 반드시 설치하세요, 보장됨.

Evaluation:

• Step 1 (Semantic): "guaranteed" 추가됨 - 원문에 없는 의미. 법적 함의 가능성.
• Step 2 (Terminology): 해당 용어집 항목 없음.
• Step 3 (Format): 포맷 완전.
• Score: 3 - 의미 추가 발생. 검수 필요.

Example 4: Score 1 (Severe Error)

원문: 데이터 삭제 후 복구할 수 없습니다.
번역: You can recover your data after deletion.
역번역: 삭제 후 데이터를 복구할 수 있습니다.

Evaluation:

• Step 1 (Semantic): 의미 완전 반대! "복구 불가" → "복구 가능". 심각한 오역.
• Step 2 (Terminology): 해당 없음.
• Step 3 (Format): 해당 없음.
• Score: 1 - 의미 반전. 사용자 오해 및 데이터 손실 위험.
