What Is Soccer Data Quality and How to Measure It
Soccer event-data quality means how accurately, completely and consistently records describe the available footage. Measure it against a documented reference sample; no accuracy score for BuildUp is asserted in this guide.
Define the reference
Choose footage and event definitions, agree reviewer criteria and record disagreements rather than silently treating opinions as ground truth.
Compare events
Check missing and duplicated records, event labels, player identity, timestamps and outcomes against the sample.
Report limitations
Record camera coverage, obscured actions, sample size and excluded minutes. A result on one sample is not a universal performance guarantee.
A practical assessment checklist
- Define sample matches, minutes and event types
- Use documented event definitions
- Review missed, extra and incorrectly labeled events
- Record uncertainty, coverage gaps and reviewer disagreement
Method, not a product certification
- Documented sample
- Explicit reference criteria
- Video checks
- Reported limitations
Why measurement needs context
A summary percentage without definitions, a denominator and sample coverage can be misleading. Ask a provider for its actual validation method and evidence. BuildUp's video-linked outputs support review, but this page does not establish measured accuracy, completeness or certification.

- Which definitions apply?
