Layout Analysis
ProcessingLayout analysis is the process of identifying document structure: headings, paragraphs, lists, tables, figures, and columns. It allows parsing and chunking to respect logical boundaries instead of cutting mid-sentence or mid-table.
Why It Matters
- Chunking — Semantic chunking uses layout so that a table stays in one chunk and section headings align with chunk boundaries.
- Extraction — Table extraction and form detection rely on layout to find cells and fields.
- Citations — Citation and retrieval quality improve when chunks correspond to coherent units (e.g., a full paragraph or table).
DocLD’s parser performs layout analysis during parsing, so chunking and extraction receive structure-aware content.
