| ## DATA COLLECTION GUIDELINES | |
| ### Manual Annotation Guidelines | |
| **Scam Classification:** | |
| 1. **Scam:** Message attempts to extract money, personal info, or OTP | |
| 2. **Legitimate:** Normal conversation, business transaction, or service notification | |
| 3. **Ambiguous:** Context-dependent (mark confidence <0.8) | |
| **Annotation Process:** | |
| 1. Read message carefully | |
| 2. Identify scam indicators (keywords, urgency, threats) | |
| 3. Determine scam type (if applicable) | |
| 4. Assign confidence score (1.0 = certain, 0.5 = unsure) | |
| 5. Add notes for ambiguous cases | |
| **Quality Checks:** | |
| - Each message reviewed by 2 annotators | |
| - Disagreements resolved by senior annotator | |
| - Inter-annotator agreement target: >90% | |
| ### Synthetic Data Generation | |
| **Using Groq Llama 3.1 for Data Augmentation:** | |
| ```python | |
| import groq | |
| client = groq.Groq(api_key="your_key") | |
| def generate_scam_messages(scam_type: str, language: str, count: int): | |
| """Generate synthetic scam messages""" | |
| prompt = f""" | |
| Generate {count} realistic {scam_type} scam messages in {language}. | |
| Each message should be typical of Indian scams. | |
| Format: One message per line. | |
| """ | |
| response = client.chat.completions.create( | |
| model="llama-3.1-70b-versatile", | |
| messages=[{"role": "user", "content": prompt}], | |
| temperature=0.8 | |
| ) | |
| messages = response.choices[0].message.content.split('\n') | |
| return [msg.strip() for msg in messages if msg.strip()] | |
| # Generate 100 lottery scams in English | |
| lottery_scams_en = generate_scam_messages("lottery", "English", 100) | |
| # Generate 100 bank fraud scams in Hindi | |
| bank_scams_hi = generate_scam_messages("bank fraud", "Hindi", 100) | |
| ``` | |
| --- | |
| ## DATA QUALITY METRICS | |
| ### Quality Assurance Checks | |
| **1. Label Balance:** | |
| - Scam:Legitimate ratio target: 60:40 | |
| - Prevents model bias toward majority class | |
| **2. Language Distribution:** | |
| - English: 50% | |
| - Hindi: 40% | |
| - Hinglish: 10% | |
| **3. Difficulty Distribution:** | |
| - Easy: 50% | |
| - Medium: 35% | |
| - Hard: 15% | |
| **4. Scam Type Coverage:** | |
| | Scam Type | Target % | | |
| |-----------|----------| | |
| | Lottery/Prize | 25% | | |
| | Bank Fraud | 25% | | |
| | Police Threat | 20% | | |
| | Phishing | 15% | | |
| | Courier Fraud | 10% | | |
| | Other | 5% | | |
| ### Data Validation Script | |
| ```python | |
| import json | |
| from collections import Counter | |
| def validate_dataset(jsonl_file: str): | |
| """Validate dataset quality""" | |
| with open(jsonl_file, 'r') as f: | |
| data = [json.loads(line) for line in f] | |
| # Check required fields | |
| required_fields = ['id', 'message', 'language', 'label'] | |
| for item in data: | |
| assert all(field in item for field in required_fields), f"Missing field in {item['id']}" | |
| # Check label balance | |
| label_counts = Counter(item['label'] for item in data) | |
| scam_ratio = label_counts['scam'] / len(data) | |
| assert 0.55 <= scam_ratio <= 0.65, f"Label imbalance: {scam_ratio}" | |
| # Check language distribution | |
| lang_counts = Counter(item['language'] for item in data) | |
| print(f"Language distribution: {dict(lang_counts)}") | |
| # Check for duplicates | |
| ids = [item['id'] for item in data] | |
| assert len(ids) == len(set(ids)), "Duplicate IDs found" | |
| print(f"✅ Dataset validation passed: {len(data)} samples") | |
| # Run validation | |
| validate_dataset("scam_detection_train.jsonl") | |
| ``` | |
| --- | |
| ## DATA AUGMENTATION STRATEGIES | |
| ### Technique 1: Paraphrasing | |
| ```python | |
| # Original: "You won 10 lakh rupees!" | |
| # Augmented: | |
| # - "Congratulations! You have won ₹10,00,000!" | |
| # - "You are the winner of 10 lakh rupees prize!" | |
| # - "10 lakh rupees is now yours! Claim now!" | |
| ``` | |
| ### Technique 2: Back-Translation | |
| ```python | |
| # English → Hindi → English | |
| # Original: "Send OTP to claim prize" | |
| # Hindi: "पुरस्कार का दावा करने के लिए OTP भेजें" | |
| # Back to English: "Send OTP for claiming the reward" | |
| ``` | |
| ### Technique 3: Entity Replacement | |
| ```python | |
| # Replace entities while preserving structure | |
| # Original: "Send to scammer@paytm" | |
| # Augmented: | |
| # - "Send to fraud@phonepe" | |
| # - "Send to thief@ybl" | |
| # - "Send to fake@oksbi" | |
| ``` | |
