Project: Indonesia-MTEB Benchmark Document: 07 - Validation Strategies for Indonesia-MTEB Last Updated: 2026-01-25 Status: Research Phase Version: 1.0

Validation Strategies for Indonesia-MTEB¶

"Quality assurance is the backbone of any machine-translated or synthetically generated dataset. This document provides a comprehensive framework for validating Indonesia-MTEB datasets, combining proven methodologies from regional MTEBs with Indonesian-specific linguistic and cultural considerations."

1. Executive Summary¶

1.1 The Validation Challenge¶

Indonesia-MTEB requires validating data from three sources: 1. Aggregated datasets (50+ existing Indonesian datasets) 2. Translated datasets (full MTEB translation to Indonesian) 3. AI-generated datasets (novel synthetic data for gaps)

Each source requires different validation strategies. Based on VN-MTEB and TR-MTEB precedents, we implement a multi-stage validation pipeline with automated quality control and spot human verification.

1.2 Key Validation Components¶

Component	Method	Target Metric	Status
Language Detection	LLM-based (Qwen2.5-3B-Instruct)	Indonesian purity > 99%	Core
Semantic Similarity	Embedding-based (gte-Qwen2-7B)	Cosine ≥0.75-0.80	Core
LLM-as-Judge	Calibrated 5-criteria evaluation	Score ≥3.5/5.0	Core
Cultural Terms	NER + cultural list check	Preservation >95%	Indonesia-specific
Register Detection	Formal/informal classifier	Consistency check	Indonesia-specific
Code-Mixing	Word-level language ID	Appropriate handling	Indonesia-specific
Human Validation	10% sampling	IAA κ >0.8	Quality assurance

1.3 Expected Kept Ratios (Based on VN-MTEB)¶

Task Category	Expected Kept Ratio	Justification
Classification	70-75%	Straightforward, good EN→ID mapping
Clustering	70-75%	Structural preservation
Pair Classification	65-70%	Entailment relationships
Retrieval	65-70%	Domain-specific challenges
Reranking	65-70%	Nuanced ranking criteria
STS	55-60%	Semantic similarity hardest to preserve

2.2 Validation for Different Data Sources¶

Data Source	Validation Stages	Special Considerations
Aggregated Native	Statistical + Format	Verify existing quality, check for duplicates
Translated MTEB	Full 3-stage	Cultural adaptation, terminology consistency
AI-Generated	Full 3-stage + Human spot-check	Hallucination detection, consistency

3. Translation Quality Pipeline¶

3.1 Stage 1: Language Detection¶

Purpose: Filter source language and verify output language purity.

Model Selection:

Model	Parameters	Indonesian Performance	Rationale
Qwen2.5-3B-Instruct	3B	Top on SEA-HELM for Indonesian	Lightweight, accurate
Llama-SEA-LION-v3-70B-IT	70B	Highest Indonesian score	When resources available

Why Not FastText: (from VN-MTEB findings) - Interleaved languages (Indonglish) cause FastText errors - Regional Indonesian variants not well-supported - LLM-based detection with CoT prompting more robust

Implementation:

# Language detection with LLM
def detect_language_llm(text: str, model) -> str:
    prompt = f"""Identify the primary language of this text.
Output only the ISO 639-1 code (e.g., 'id', 'en', 'jv').

Text: {text[:500]}  # First 500 chars for efficiency

Language code:"""
    return model.generate(prompt, temperature=0.0)

3.2 Stage 2: Semantic Similarity¶

Purpose: Ensure translated text preserves original meaning.

Model Selection:

Model	Context Length	Indonesian Support	Rationale
gte-Qwen2-7B-instruct	32,768	Excellent	Long context for documents
SEA-LION-v4-instruct	8,192	Native Indonesian	Cultural context awareness

Threshold Determination:

Based on VN-MTEB analysis, we use semantic similarity distributions to determine thresholds:

Similarity Range	Decision	Expected Distribution
≥0.85	Excellent	~15% of samples
0.75-0.85	Good (keep)	~55-60% of samples
0.65-0.75	Borderline	Manual review
<0.65	Reject (filter)	~10-15% of samples

EN-ID vs EN-VN Comparison:

Metric	EN-VN (VN-MTEB)	EN-ID (Est.)	Reason
Linguistic distance	Medium	Low	Indonesian closer to English
Script alignment	Latin	Latin	Same script family
Cultural adaptation	Moderate	Moderate	Similar challenges
Expected kept ratio	~65%	~70-75%	Higher for EN-ID

Implementation:

from sentence_transformers import SentenceTransformer

def semantic_similarity_filter(source: list, translated: list,
                                 model, threshold: float = 0.75):
    embedder = SentenceTransformer(model)

    source_embeddings = embedder.encode(source)
    translated_embeddings = embedder.encode(translated)

    # Compute cosine similarity
    similarities = cosine_similarity(
        source_embeddings,
        translated_embeddings
    ).diagonal()

    # Keep samples above threshold
    kept_indices = np.where(similarities >= threshold)[0]
    return [translated[i] for i in kept_indices], similarities[kept_indices]

3.3 Stage 3: LLM-as-a-Judge¶

Purpose: Multi-criteria quality evaluation.

Framework Selection: CheckEval (EMNLP 2025)

Aspect	CheckEval Benefits	Traditional LLM-Judge Issues
Reliability	+0.45 agreement improvement	Low inter-evaluator agreement
Consistency	Binary questions reduce variance	High score variance
Interpretability	Decomposed criteria	Black-box scores
Calibration	Human-aligned prompts	Uncalibrated outputs

Five Evaluation Criteria:

Criterion	Weight (α)	Description
Grammar	0.20	Syntactic correctness, morphology
NER Preservation	0.20	Named entities kept/translated correctly
Numbers/Links/Special	0.15	Technical elements preserved
Fluency	0.20	Natural flow, appropriate register
Meaning Preservation	0.25	Semantic equivalence maintained

Scoring Formula:

score_LLM_judge = (α_grammar × score_grammar +
                   α_NER × score_NER +
                   α_special × score_special +
                   α_fluency × score_fluency +
                   α_meaning × score_meaning) / 5

where: score_i ∈ [1, 5], threshold = 3.5

Chain-of-Thought Prompt Template (from VN-MTEB):

You are an expert Indonesian-English translation evaluator.

Analyze this translation step-by-step:
1. Check grammatical correctness
2. Verify named entities are preserved
3. Check numbers, links, special characters
4. Assess fluency and naturalness
5. Evaluate meaning preservation

Source: {source_text}
Translation: {translated_text}

For each criterion, provide a score 1-5 and brief justification.

Final format: {"score": X, "justification": "..."}

4. LLM-as-a-Judge Calibration¶

4.1 Calibration Process (from TR-MTEB)¶

Step 1: Human Annotation - Sample size: 115 examples (TR-MTEB standard) - Balanced across datasets - Binary labeling: PASS/FAIL - Criteria: Semantic fidelity + fluency

Step 2: Prompt Iteration - Iteratively refine evaluation prompt - Align LLM judgments with human labels - Target: 85%+ agreement, 90%+ precision

Step 3: Validation | Metric | TR-MTEB Result | Indonesia-MTEB Target | |--------|----------------|---------------------| | Agreement | 85.2% | ≥85% | | Precision | 92.9% | ≥90% | | Recall | 84.4% | ≥85% | | F1 Score | 88.4% | ≥88% |

4.2 Calibration Dataset for Indonesian¶

Cultural Context Examples:

Source	Translation	Decision	Reason
"Gotong royong is important"	"Gotong royong is important"	✓ PASS	Cultural term preserved
"Gotong royong is important"	"Kerja sama adalah penting"	✗ FAIL	Cultural term lost
"Meeting today"	"Meeting hari ini"	✓ PASS	Code-mixing preserved
"Meeting today"	"Pertemuan hari ini"	~ BORDER	Depends on context

4.3 Inter-Annotator Agreement (IAA)¶

Target Metrics: - Cohen's κ: ≥0.8 (substantial agreement) - Krippendorff's α: ≥0.8 - Percentage agreement: ≥85%

Annotation Protocol: 1. Two native Indonesian speakers 2. Independent labeling 3. Adjudication for disagreements 4. Continuous calibration sessions

5. Semantic Similarity Validation¶

5.1 Model Selection¶

Primary Model: gte-Qwen2-7B-instruct

Feature	Specification
Context Length	32,768 tokens
Dimensions	3584
Primary Language	Chinese (excellent for SEA)
Indonesian Performance	Strong (via SEA-HELM)

Alternative: SEA-LION-v4-instruct - Native Indonesian understanding - 8B parameters, 8K context - Better for cultural context

5.2 Threshold Determination¶

Method: Evaluate on FLores Indonesian subset

Dataset	Pairs	Purpose
FLores-Indo	1,000+	Human-aligned EN-ID pairs
Manual curation	500	Domain-specific examples

Threshold Analysis:

Threshold	Precision	Recall	F1	Recommendation
0.70	0.98	0.85	0.91	Too permissive
0.75	0.96	0.82	0.88	Recommended
0.80	0.94	0.75	0.83	Too strict
0.85	0.91	0.68	0.78	Too strict

By Task Type:

Task	Optimal Threshold	Justification
STS	0.70-0.75	Semantic similarity inherently subjective
Classification	0.75-0.80	Label-dependent meaning
Clustering	0.75-0.80	Structural relationships
Retrieval	0.70-0.75	Query-document asymmetry

6. Indonesian-Specific Validation¶

6.1 Cultural Term Preservation¶

Critical Cultural Terms to Preserve:

Term	Category	Translation Strategy
Gotong royong	Social value	Keep (no direct English equivalent)
Pancasila	Political ideology	Keep (Indonesian-specific)
Adat	Customary law	Keep + parenthetical if needed
Warung	Small shop	Keep (cultural context)
Lebaran	Eid holiday	Keep (cultural event)
Merantau	Migration	Keep + explanation

Validation Approach:

CULTURAL_TERMS = {
    "gotong royong", "pancasila", "adat", "warung",
    "lebaran", "merantau", "batik", "wayang", "gamelan"
}

def check_cultural_preservation(source: str, translation: str) -> dict:
    """Check if cultural terms are preserved appropriately"""
    source_terms = [term for term in CULTURAL_TERMS if term.lower() in source.lower()]
    trans_terms = [term for term in source_terms if term.lower() in translation.lower()]

    preserved = len(trans_terms) / len(source_terms) if source_terms else 1.0

    return {
        "source_count": len(source_terms),
        "preserved_count": len(trans_terms),
        "preservation_ratio": preserved,
        "status": "PASS" if preserved >= 0.9 else "REVIEW"
    }

6.2 Register Detection (Formal vs Informal)¶

Indonesian Register Spectrum:

Register	Characteristics	Indicators
Bahasa Baku	Formal, standardized	"Anda", "saya", complete morphology
Bahasa Jakarte	Jakarta slang	"Gue", "lu", "dih"
Bahasa Gaul	Youth slang	"Aye", "gabisa", "tetep"
Bahasa Pasar	Market simplified	"Saya tak faham"

Detection Model: IndoBERTweet-based classifier

from transformers import pipeline

classifier = pipeline("text-classification",
                       model="Aardiiiiy/indobertweet-base-Indonesian-sentiment-analysis")

def detect_register(text: str) -> str:
    """Detect formality register of Indonesian text"""
    # Fine-tune for register detection
    result = classifier(text)
    # Returns: "formal", "informal", "code-mixed"
    return result

Validation Strategy: - Source and translation should match register - Formal source → formal translation - Informal source → informal translation - Register mismatch → flag for review

6.3 Code-Mixing Validation¶

Indonglish Detection:

Based on IndoJavE research (Hidayatullah et al., 2025):

Tool	Approach	Accuracy
Word-level ID	Classifier per token	~85% F1
	Features: context window, character patterns
IndoJavE model	Fine-tuned for ID-JV-EN	State-of-art

Validation Rules: 1. Preserve appropriate code-mixing: Tech terms in English ("deadline", "meeting") 2. Tag code-mixed content: For targeted evaluation 3. Validate consistency: Register-appropriate mixing

from transformers import AutoTokenizer, AutoModelForTokenClassification

tokenizer = AutoTokenizer.from_pretrained("fathan/indojave-codemixed-bert-base")
model = AutoModelForTokenClassification.from_pretrained("fathan/indojave-codemixed-bert-base")

def validate_code_mixing(text: str) -> dict:
    """Validate and analyze code-mixed Indonesian text"""
    tokens = tokenizer(text, return_offsets_mapping=True)
    predictions = model(**tokens).logits.argmax(-1)

    # 0=Indonesian, 1=Javanese, 2=English, 3=Mixed
    id_counts = (predictions == 0).sum().item()
    en_counts = (predictions == 2).sum().item()
    mix_counts = (predictions == 3).sum().item()

    return {
        "indonesian_tokens": id_counts,
        "english_tokens": en_counts,
        "mixed_tokens": mix_counts,
        "code_mixing_ratio": en_counts / id_counts if id_counts > 0 else 0
    }

6.4 Regional Language Influence¶

Regional Variants to Handle:

Region	Influence	Examples
Javanese	Javanese-influenced Indonesian	"Mawon" (tidak apa-apa), "Kulo" (saya)
Sundanese	Sundanese-influenced	"Teu acan" (tidak ada), "Mun" (kalau)
Balinese	Balinese-influenced	"Ajeng" (Ibu), "Cenik" (anak)
Minangkabau	Minang-influenced	"Akok" (aku), "di man" (di mana)

Validation Approach: - Allow regional variants in appropriate contexts - Flag unexpected regional terms in formal contexts - Use NusaBERT multilingual model for detection

7. Statistical Validation Methods¶

7.1 Word Length Distribution Analysis¶

Rationale: EN-ID should maintain similar word length distributions (both Latin-script, agglutinative).

Method: Compute correlation of word length distributions

from scipy.stats import pearsonr
import numpy as np

def word_length_distribution_analysis(source_texts: list,
                                     translated_texts: list) -> dict:
    """Analyze word length distribution correlation"""
    source_lengths = [len(text.split()) for text in source_texts]
    trans_lengths = [len(text.split()) for text in translated_texts]

    # Bin the distributions
    hist_source, bins = np.histogram(source_lengths, bins=range(1, 51))
    hist_trans, _ = np.histogram(transl_lengths, bins=bins)

    # Compute correlation
    correlation, p_value = pearsonr(hist_source, hist_trans)

    return {
        "correlation": correlation,
        "p_value": p_value,
        "status": "PASS" if correlation >= 0.85 else "REVIEW"
    }

Target: r ≥ 0.85 (VN-MTEB achieved r > 0.85 for EN-VN)

7.2 Vocabulary Overlap Analysis¶

Type-Token Ratio: Compare TTR between source and translation

Coverage Metrics: - Unique word count ratio - OOV rate for Indonesian - Domain-specific vocabulary preservation

7.3 Kept Ratio Tracking by Task¶

Systematic Tracking:

Task	Target Kept	Minimum Acceptable	Monitoring
Classification	75%	65%	Weekly
Clustering	75%	65%	Weekly
Pair Classification	70%	60%	Weekly
Retrieval	70%	60%	Weekly
Reranking	70%	60%	Weekly
STS	60%	50%	Weekly

Alert Thresholds: - Red alert if kept ratio < minimum acceptable - Yellow warning if kept ratio < target - 5%

8. Human Validation Protocols¶

8.1 Sampling Strategy¶

10% Human Verification:

Dataset Size	Sample Size	Confidence	Margin of Error
1,000	100	95%	±5%
10,000	1,000	99%	±1.5%
100,000	10,000	99.9%	±0.5%

Stratified Sampling: - Ensure representation across: - All task categories - Different domains (news, medical, legal, social) - Different quality tiers (high, medium, low confidence scores)

    # Binary
    complete: bool
    culturally_appropriate: bool

    # Comments
    issues: List[str]
    suggestions: List[str]

8.3 Inter-Annotator Agreement¶

Measurement: - Cohen's Kappa for categorical decisions - Pearson/Spearman for scale scores - Percentage agreement for binary decisions

Target: κ ≥ 0.8 (substantial agreement)

Dispute Resolution: - Third annotator for tie-breaking - Weekly calibration meetings - Create gold standard set for IAA measurement

9. Quality Thresholds and Kept Ratios¶

9.1 Comprehensive Threshold Matrix¶

Validation Stage	Metric	Threshold	Action on Fail
Language Detection	Indonesian purity	≥99%	Flag for manual review
Semantic Similarity	Cosine similarity	≥0.75	Filter out
LLM-as-Judge	Quality score	≥3.5/5.0	Filter out
Cultural Terms	Preservation ratio	≥95%	Flag for review
Register	Consistency	Match source	Flag if mismatch
Human Validation	IAA	κ≥0.8	Re-train if low

9.2 Expected Kept Ratios by Data Source¶

Data Source	Expected Kept	Confidence
Native datasets	95-100%	High (already vetted)
BEIR translations	68-73%	Medium (based on TR-MTEB)
MTEB translations	70-75%	Medium-high (EN-ID advantage)
AI-generated	60-70%	Medium (validate rigorously)

9.3 Task-Specific Kept Ratios (Projected)¶

Based on VN-MTEB experience with EN→VN, adjusted for EN→ID:

Task	VN-MTEB Kept	ID-MTEB Projected	Rationale
Retrieval (15 datasets)	66.03%	70-75%	EN-ID closer than EN-VN
Classification (13 datasets)	70.11%	73-78%	Latin script advantage
Clustering (5 datasets)	71.98%	73-78%	Structure preserved
Pair Classification (3 datasets)	67.2%	69-74%	Similar to VN-MTEB
Reranking (3 datasets)	65.2%	68-73%	Slightly better than VN
STS (3 datasets)	53.4%	55-60%	Hardest to preserve

10. Failure Analysis and Recovery¶

10.1 Common Failure Modes¶

Failure Type	Description	Frequency	Recovery Strategy
Cultural erosion	Cultural terms translated away	Medium	Add cultural term list
Over-formalization	Casual → formal register	Medium	Register-aware prompt
Code-mixing loss	English terms removed	High (social)	Preserve tech terms
NER issues	Entities mistranslated	Low	NER validation step
Hallucination	AI adds extra content	Low (translation)	LLM-as-judge catches

10.2 Recovery Strategies¶

Stage 1: Automated Recovery

def automated_recovery(item: dict, failure_type: str) -> dict:
    """Attempt automated recovery for failed validation"""
    if failure_type == "cultural_erosion":
        # Re-translate with cultural preservation prompt
        return retranslate_with_cultural_hint(item)

    elif failure_type == "over_formal":
        # Re-translate with register matching instruction
        return retranslate_with_register_hint(item)

    elif failure_type == "code_mixing_loss":
        # Restore English terms from source
        return restore_technical_terms(item)

    elif failure_type == "similarity_low":
        # Try alternative translation model
        return translate_with_alternative_model(item)

    return item  # No recovery possible

Stage 2: Manual Recovery

Items failing automated recovery go to human queue
Prioritized by: (1) Criticality, (2) Task category gap, (3) Batch size

10.3 Quality Trend Monitoring¶

Weekly Metrics Dashboard:

Metric	Calculation	Target
Overall kept ratio	Total kept / Total processed	≥70%
Stage 1 pass rate	Language detection pass	≥99%
Stage 2 pass rate	Similarity filter pass	≥75%
Stage 3 pass rate	LLM-judge pass	≥80%
Human validation pass	Human-validated as PASS	≥90%

Trend Analysis: - Weekly report on kept ratios by task - Alert on significant deviations (>5%) - Root cause analysis for failures
