Content Classification And Categorization With Custom Tags

via “custom element classification and tagging”

IBM's document converter — PDFs, DOCX to structured markdown with OCR and table extraction.

Unique: Integrates custom classifiers into the document processing pipeline as a post-processing step on the layout-analyzed AST, enabling domain-specific element tagging without modifying core parsing logic

vs others: More flexible than rule-based extraction because it supports learned classifiers; more integrated than external classification tools because it operates on the parsed document structure rather than raw text
