DocMaster: A Hierarchical Structure-Aware System for Document Analysis

arXiv:2607.08539v1 Announce Type: cross Abstract: Leveraging large language models (LLMs) to analyze complex documents -- such as academic papers, technical manuals, and financial reports -- has emerged as a mainstream and critical task in both research and industry. In practice, users must first filter relevant documents from large collections and then conduct in-depth analysis (e.g. question answering) over the selected subset, yet existing systems flatten documents into plain-text chunks, discarding the rich hierarchical structures (sections, tables, figures, equations) and degrading downst

Why this matters
Why now

The proliferation of increasingly complex documents meets the rising demand for efficient information extraction from large language models, creating a pressure point for better parsing methods.

Why it’s important

This development addresses a critical limitation in current LLM-based document analysis, potentially unlocking significantly greater utility and accuracy for complex information extraction across industries.

What changes

Existing systems that flatten documents into plain text will be rapidly superseded by hierarchical, structure-aware approaches, fundamentally changing how LLMs interact with and derive insights from structured information.
