Real-world data

What is real-world data?

Quick answer

Real-world data is information generated by real activity — customer conversations, transactions, field reports, machine logs, documents — rather than created artificially for a model. AI developers use it to train and test systems on the messy, varied situations they will meet in practice. It is often proprietary, so it is usually obtained by licensing it from the organisation that holds it.

Why it matters#

Models trained only on curated or synthetic examples can fail on edge cases. Real-world data captures the variation, errors and context of real operations.

In healthcare, the term also has a specific regulatory meaning: data relating to patient health status collected outside clinical trials.

Examples#

Support tickets and chat logs
Sales and service call recordings
Insurance claims files
Construction daily logs and RFIs
Equipment maintenance logs and sensor readings
