In a world where security questionnaires multiply and regulatory standards shift at breakneck speed, static check‑lists no longer suffice. This article introduces a novel AI‑driven Dynamic Compliance Ontology Builder—a self‑evolving knowledge model that maps policies, controls, and evidence across frameworks, automatically aligns new questionnaire items, and fuels real‑time, auditable responses within the Procurize platform. Learn the architecture, core algorithms, integration patterns, and practical steps to deploy a living ontology that turns compliance from a bottleneck into a strategic advantage.
