## Strategy Rationale by Domain
### Finance
- **Financial Data Integration**: Incremental for streaming data; most_recent for time-sensitive financial data
- **Fraud Detection**: Graph-based clustering for fraud groups; expert_review for fraud assessment
### Biomedical
- **Drug Discovery**: Semantic matching for drug compounds; voting for research source aggregation
- **Genomic Variants**: Group method for related variants; credibility weighting for research sources
### Cybersecurity
- **Real-Time Anomaly**: Pairwise for real-time streams; keep_first for first detection priority
- **Threat Intelligence**: Exact matching for IOCs; highest_confidence for threat classification
### Blockchain
- **DeFi Protocols**: Group method for related protocols; keep_last for latest protocol info
- **Transaction Networks**: Hierarchical clustering for nested groups; temporal for time-sensitive data
### Intelligence
- **Criminal Networks**: Fuzzy matching for intelligence data; credibility weighting for intelligence sources
- **Intelligence Analysis**: Batch for multi-source integration; merge_all to combine all intelligence sources
### Renewable Energy
- **Energy Markets**: Pairwise for real-time market data; most_recent for time-sensitive energy data
### Supply Chain
- **Supply Chain Integration**: Incremental for continuous updates; credibility weighting for supply chain sources

## Key Patterns
1. **Real-Time Systems**: Use `pairwise` + `keep_first` + `first_seen`
2. **Time-Sensitive Data**: Use `temporal` + `most_recent`
3. **Multi-Source Integration**: Use `batch` + `merge_all` + `voting`
4. **Medical/Research**: Use `credibility_weighted` for authoritative sources
5. **Fraud/Security**: Use `graph_based` + `logical` + `expert_review`
6. **Exact Matching Required**: Use `exact` strategy (IOCs, identifiers)
