Auto‑tagging and classification with SharePoint Premium and Microsoft Purview helps you apply consistent metadata (e.g. document type, business area, record category) at scale without relying solely on users filling in fields. Models can classify documents based on their content and suggest appropriate content types, retention labels or templates, improving both findability and lifecycle management.
Sensitive information and PII can be detected automatically using built‑in or custom sensitive information types, enabling you to auto‑apply retention or DLP policies and reduce manual review effort. Together, these capabilities turn unmanaged file shares into governed information assets, making downstream search, chatbots and analytics more accurate because the underlying content is cleaner and better described.
