AML/KYC/sanctions screening automation using entity resolution and graph analytics
The automated application of entity resolution and graph analytics to identify and monitor financial crime risks by linking disparate data points into a unified view of individuals and organizations across AML, KYC, and sanctions screening processes.
This skill drastically reduces false positives, accelerates investigation cycles, and uncovers sophisticated, network-based financial crime patterns that rule-based systems miss. It directly lowers operational costs, enhances regulatory compliance, and mitigates multi-million dollar fines and reputational damage.

How to Learn AML/KYC/sanctions screening automation using entity resolution and graph analytics
1. Master the core regulatory framework: Understand the objectives of the Bank Secrecy Act (BSA), FATF Recommendations, and OFAC sanctions lists. 2. Learn the fundamentals of entity resolution: study deterministic vs. probabilistic matching, and familiarize yourself with concepts like match scores, survivorship rules, and golden record creation. 3. Acquire basic graph theory: understand nodes, edges, properties, and traversal algorithms (e.g., shortest path, community detection).
Move beyond theory by implementing a screening pipeline on a sample dataset. Use a tool like Senzing or IBM InfoSphere to build an entity resolution model, tuning match weights for common attributes (name, address, DOB). Integrate the resolved entity graph with a graph database (e.g., Neo4j) to run a simple pattern query, such as finding all entities within two hops of a sanctioned party. Common mistake: over-reliance on name-only matching without incorporating contextual data, leading to high false negative rates.
Architect an end-to-end, scalable automation solution. This involves designing the data ingestion and normalization layer, selecting and tuning enterprise-grade entity resolution software, and defining graph-based risk typologies (e.g., layering, shell company networks). Advanced mastery includes building explainable AI models to prioritize alerts, establishing performance KPIs (e.g., false positive reduction rate, investigation time savings), and mentoring teams on interpreting graph-driven insights for SAR filing.
Practice Projects
Beginner
Project
Build a Basic Sanctions Screening Graph
Scenario
You are given a CSV of customer data (names, addresses, IDs) and a separate CSV of OFAC SDN list entries. The goal is to identify potential matches using more than just name similarity.
How to Execute
1. Use Python (pandas) to clean and standardize both datasets. 2. Employ a library like `recordlinkage` or `fuzzywuzzy` to perform probabilistic matching on name, address, and date of birth fields, calculating a composite match score. 3. Load the customer data and high-confidence matches into a graph database (e.g., Neo4j) as nodes, creating relationships like `HAS_ADDRESS` or `SHARES_ID`. 4. Write a Cypher query to find all customers connected to a sanctioned entity node via any relationship path.
Intermediate
Project
Develop a UBO Network Unmasking Model
Scenario
A corporate client presents a complex ownership structure. Your task is to build an automated pipeline to identify the ultimate beneficial owner (UBO) and map connections to other high-risk entities in your internal database.
How to Execute
1. Ingest corporate registry data and parse ownership percentages from documents. 2. Model the data as a graph: Companies as nodes, ownership as directed edges with a `percentage` property. 3. Implement a graph algorithm (e.g., recursive traversal) to calculate UBO by following ownership chains and summing percentages until the threshold (e.g., 25%) is met. 4. Enrich the graph by linking UBO nodes to your internal AML watchlist and PEP database. 5. Design a query to flag any UBO that has a direct or indirect relationship (e.g., via shared addresses or directors) to a flagged entity.
Advanced
Case Study/Exercise
Design an Alert Triage and Prioritization Engine
Scenario
Your institution's automated screening system generates 10,000 alerts daily. Investigation teams are overwhelmed, leading to backlog and risk. Design a system to triage and prioritize these alerts based on entity risk and network centrality.
How to Execute
1. Define a risk scoring model for resolved entities that incorporates static attributes (e.g., PEP status) and dynamic graph metrics (e.g., degree centrality, betweenness centrality in a transaction graph). 2. Architect a pipeline where the entity resolution engine feeds resolved entities into a risk model and a graph analytics engine. 3. Develop a decision layer that uses the combined risk score to assign alerts to priority queues (e.g., Critical, High, Medium, Low). 4. Build a feedback loop where investigator dispositions on alerts are used to retrain the risk model, improving prioritization accuracy over time.

Senzing is an industry leader for turnkey entity resolution. Neo4j and TigerGraph are leading graph databases for modeling and querying complex relationships. Use these to build the core data fusion and analytics layer.
Use Python libraries for prototyping and data wrangling. Gephi is for exploratory graph visualization. Spark GraphFrames enables scalable graph analytics on large datasets, critical for enterprise deployment.
These provide the 'why' behind the technical skill. They define the risks, red flags, and reporting requirements that your automated systems must detect and address. They are essential for designing relevant graph patterns and risk models.
Interview Questions
Answer Strategy
Demonstrate an understanding of data complexity and a structured methodology. The strategy is to outline a multi-stage approach: 1) Data Ingestion & Normalization (handling transliteration, language-specific rules), 2) Tiered Matching (using deterministic rules for exact IDs, then probabilistic for fuzzy matches), 3) Contextual Enrichment (leveraging addresses, dates, associates), and 4) Threshold Tuning & Explainability. Sample Answer: 'I would start with a rigorous data normalization layer to handle transliteration and script conversion. The matching engine would use a tiered approach: deterministic rules for exact government IDs, then a probabilistic model weighing attributes like name, date of birth, and nationality. Crucially, I'd incorporate contextual matching on addresses and known associates to disambiguate common names. The final match score threshold would be tuned based on a cost-benefit analysis between false negatives and investigation workload, with full match reason explainability for auditors.'
Answer Strategy
This tests practical experience and the ability to articulate business impact. Use the STAR method (Situation, Task, Action, Result) to structure your response. Focus on the specific graph algorithms or patterns you applied. Sample Answer: 'In my previous role, our transaction monitoring was missing a layering scheme. I imported 6 months of transaction data into a graph database and used community detection algorithms to identify tight-knit clusters of accounts with rapid, circular fund flows. The graph visualization immediately revealed a central 'funnel' account receiving from multiple small entities and disbursing to a single high-risk jurisdiction-a pattern invisible in tabular reports. This led to the filing of three significant SARs and a 40% reduction in false negatives for that typology.'
