The approach targets heterogeneous formats including PDFs, Word documents, presentations, and scans whose content is locked inside complex visual layouts, multi-column pages, and dense tables, which rule-based extraction and OCR struggle to handle.", "body_md": "Retrieval-Augmented Generation (RAG) systems over enterprise knowledge bases must ingest heterogeneous document formats -- PDFs, Word documents, presentations, and scans -- whose content is locked inside complex visual layouts, multi-column pages, and dense tables.
