Document AI & Document Understanding
Document AI and document understanding refer to technologies that parse, analyze, and extract meaning from documents so they can be searched, summarized, or used to answer questions. Combined with RAG and LLMs, they power intelligent knowledge bases and Q&A systems.
What is Document Understanding?
Document understanding goes beyond OCR or plain text extraction. It includes:
- Layout and structure: Headings, tables, lists, and sections.
- Semantic meaning: What each chunk is about, for better retrieval.
- Entity and relation extraction: Key terms, dates, and relationships.
- Chunking strategies: Splitting documents into optimal pieces for retrieval and generation.
Supported Document Formats
Modern document AI pipelines typically support:
- PDF (native and scanned with OCR)
- Word (.docx)
- Markdown and plain text
- HTML and web pages
- Structured data (tables, spreadsheets)
WeKnora's document understanding engine handles these formats and produces chunks ready for vector indexing and semantic search.
Document AI for RAG and Knowledge Bases
In a RAG or knowledge-base pipeline, document AI is the first stage: raw files are parsed and chunked, then embedded and stored. When users ask questions, semantic search retrieves the right chunks, and the LLM uses them to generate answers. Strong document understanding improves retrieval quality and answer accuracy.
