Duplicate Detection & Consolidation with AI
Find and merge duplicates with 98% detection accuracy and 95% merge precision. Consolidate records intelligently while preserving lineage—cutting manual effort by up to 90%.
Executive Summary
AI-powered deduplication uses fuzzy matching and ML to detect and consolidate duplicate records across systems. Expect a 98% detection rate, 80% faster consolidation, 95% merge accuracy, and ~90% less manual effort—all with complete audit trails and historical preservation.
Why Use AI for Duplicate Reduction?
AI ensembles (exact, phonetic, and semantic matching) uncover hard-to-spot duplicates, resolve field conflicts by confidence rules, and maintain data lineage so reporting, attribution, and compliance remain intact.
Agents continuously scan new and historical data, apply normalization before merge, and learn from reviewer feedback to improve future match quality. Result: cleaner routing, higher deliverability, and trustworthy analytics.
What Changes with AI-Powered Deduplication?
🔴 Manual Process (7 steps, 16–20 hours)
- Duplicate identification via database queries (4–5h)
- Record comparison & validation (4–5h)
- Data mapping & field prioritization (3–4h)
- Merging with data preservation (3–4h)
- Testing & validation (1–2h)
- Documentation & audit trail creation (1h)
- Stakeholder communication & training (30–60m)
🟢 AI-Enhanced Process (4 steps, 2–3 hours)
- AI duplicate detection with confidence scoring (~1h)
- Automated record comparison with conflict resolution (30–60m)
- Intelligent merge with lineage tracking (~30m)
- Real-time validation, reporting, and stakeholder alerts (15–30m)
TPG standard practice: Normalize fields pre-merge, preserve originals for rollbacks, and route low-confidence matches to reviewers with full source lineage and impact analysis.

Frequently Asked Questions
How does AI decide which field values to keep?
Rules weight recency, source trust, completeness, and verification. Low-confidence conflicts are routed to reviewers with side-by-side lineage.
Will historic activity and attribution be preserved?
Yes. Merges retain activity history and IDs; we maintain redirect links and audit trails so reporting and attributions remain intact.
What about false positives?
Confidence thresholds and reviewer queues mitigate risk. Feedback loops retrain models to reduce future false positives/negatives.
How often should we run deduplication?
Continuously monitor inbound data and schedule weekly full sweeps. Revisit thresholds quarterly based on drift in sources and usage.
