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}.

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" ``` --- **Document Status:** Production Ready **Dataset Repository:** To be created in `data/` folder **Next Steps:** Generate full datasets (10K+ samples), validate quality, version control **Update Schedule:** Weekly during development, monthly in production
