Matching is key!

MDM for customer data

Matching is a “catch-all” term for comparing records, detecting duplicates and combining them into the “true” version of a record (Golden record)

Matching is a complicated process:

• Different data formats

• Volatility of customer data

• Human errors

• Expanding internationalisation, i.e. linguistic diversity

• Industry- or company-specific requirements

Matching customer data across heterogeneous sources

• Deterministic matching: Country- and subject-specific knowledge, business rules, phonetic conversion and comparison, algorithms:

• Probabilistic matching: Fuzzy logic, fault-tolerance algorithms, contextual frequency rules, patterns

To deliver the best required result, matching engines must combine both approaches. The better a matching is able to determine what is what in a particular context, the better the probability calculation of a certain match or a certain non-match. It is, in essence, the same way we humans apply matching.

High precision matching: combining adeterministic and a probabilistic approach

Mimicking human interpretation of customer data is the road to successful high precision matching: What is what?

Natural Language Processing

• Test with a lot of of real data

• Profile data sources in order to assess accuracy and completeness of data

• Compare and benchmark matching results

• Combine deterministic and probabilistic approaches

• Consider the interface for data stewardship (doubtful matches)

• Consider current AND future requirements

• Think across the border

To keep in mind when assessing matching capabilities for your MDM solution

The quality of your MDM solution is only as powerful as the quality of your matching engine
