Document Parsing

Follow this topic Ask about this topic

Document parsing turns PDFs and page images into structured content that can support search, retrieval-augmented generation, and automated workflows. Systems range from OCR and layout-detection pipelines to end-to-end vision-language models, with training methods such as synthetic data, reinforcement learning, and parallel decoding. Evaluation increasingly tests tables, formulas, reading order, multilingual content, and multi-page structure across digital, degraded, and camera-captured documents. A central challenge is achieving reliable structural and semantic fidelity on real-world documents while keeping inference fast and affordable.

Long-Document VQA Document QA Evidence Retrieval Document Parsing

Open paper AskPDF arXiv

Visual document understanding is essential for acquiring knowledge from visually rich documents and is attracting growing research interest. Existing surveys emphasize architectures or technical approaches, with limited attention to how task bottlenecks shape technical choices and research priorities. We present a task-centric survey that decomposes long-document visual question answering (VQA) into four components: document parsing, evidence organization and retrieval, generator organization and learning, and evaluation. For each, we develop a fine-grained taxonomy and trace motivations, technical responses, and cross-component connections. We focus on explicit retrieval while covering direct reading. Our temporal analysis traces expanding priorities from multimodal content understanding to sufficient, high-fidelity evidence acquisition and sustained evidence management. We outline future directions in evidence sufficiency, verifiable and correctable understanding, and budget-aware coordination, with an outlook on continual document understanding.
