annotation
What It Means
Annotation is the process of adding explanatory notes, labels, or documentation to data, code, or system requirements to make them more understandable. It's like adding sticky notes or comments that explain what something means, why it exists, or how it should be used. These annotations help teams understand context and make informed decisions about the annotated item.
Why Chief AI Officers Care
Poor or missing annotations create significant operational risks when AI teams can't understand legacy systems, data sources, or model requirements, leading to costly errors and delays. Proper annotation practices are essential for regulatory compliance, as auditors need clear documentation of AI system decisions and data handling. Well-annotated systems reduce onboarding time for new team members and enable faster troubleshooting when issues arise.
Real-World Example
A healthcare AI company annotates their patient data with detailed notes explaining which fields contain personally identifiable information, how each data point was collected, and what preprocessing was applied. When regulators audit their system, these annotations allow them to quickly demonstrate compliance with HIPAA requirements and explain their data governance practices.
Common Confusion
People often confuse annotation with simple labeling or tagging, but annotation specifically refers to adding explanatory context and documentation rather than just categorical labels. It's also mistaken for automated metadata generation, when effective annotation typically requires human insight about business context and operational requirements.
