The VACUUM model is a structured framework comprising six dimensions - Valid, Accurate, Consistent, Uniform, Unify, and Model - designed to ensure reliable data quality in document processing and AI workflows. The article highlights that 80% of an AI project’s effort is often spent on cleaning and preparing data rather than building models, underscoring why data quality fundamentally determines automation success. Organizations can apply VACUUM principles through tools like Parseur to transform raw documents into trustworthy, standardized data ready for enterprise systems.
