Categorization is the process through which ideas and objects are recognized, differentiated, classified, and understood.
Automatic categorization is technology designed to control the flood of unstructured, non-indexed, and unorganized digital content that threatens to swamp knowledge workers in corporations and government.
Auto-categorization software tools provide the means to categorize digital content according to predefined taxonomies, to extract concepts and entities for the development of taxonomies and to tag content with subject-related metadata tags.
