The auditor used Data Mining.

Data mining involves exploring large datasets to identify patterns, anomalies, or relationships.

ISO/IEC 20546:2019 Clause 3.5 defines data mining as: “The process of discovering patterns, correlations, anomalies, and associations within large datasets.”

In ISO/IEC 42001:2023, auditors are encouraged in Clause 9.2.2 to use appropriate technological tools to analyze AI system behavior, including using big data technologies for pattern recognition during audits.
