UnverifiedPDF解析中重建文档逻辑结构通常需要结合启发式规则或专门的布局分析模型如LayoutLM、Nougat79% similarUnverifiedLayout-aware PDF extraction performs significantly better than flattening all content into plain text, especially in documents containing tables and multi-column layouts.74% similarVerifiedPDF is essentially a page description language oriented toward printing, storing the absolute coordinates of characters rather than semantic structure internally, leading to parsing challenges such as the need for OCR with scanned versions, disordered reading order in multi-column layouts, and loss of row-column relationships in tables.73% similarVerifiedLarge-model-driven parsers adopt a vision-language joint understanding approach, rendering PDF pages as images, extracting layout features via a visual encoder, and then combining a language model to reason and output structured text.71% similar
