Introduction
The rapid proliferation of scientific literature, predominantly in PDF format, has underscored the critical need for advanced tools capable of efficient and accurate understanding, summarization, and content optimization. These tools struggle to maintain the semantic integrity and visual fidelity required for sophisticated content manipulation .
Concurrently, the emergence of Large Language Models (LLMs) and Vision-Language Large Models (LVLMs) has demonstrated unprecedented capabilities in understanding and generating human-like text and interpreting visual information, with recent advancements focusing on improved generalization , handling chaotic contexts , and visual in-context learning , even extending to specialized domains like medical imaging with abnormal-aware feedback.
Motivated by these limitations, this research introduces DocRefine, an innovative framework designed to address the aforementioned challenges.
While it can address some structural aspects, its adaptability to complex, ambiguous instructions and deep multimodal reasoning is limited compared to comprehensive LVLM-driven systems.
These include, but are not limited to, targeted text rewriting, comprehensive grammar and spelling correction, factual information addition or deletion, precise correction of numerical data within tables, adjustment of figure titles or legends, and even generating new text content to.
Methodology
We compare DocRefine against several strong baselines, including an LLM-only approach, an LVLM-In-Context method, and a Hybrid Rule-LLM system. \u2022 We design and implement a sophisticated multi-agent system, comprising Layout & Structure Analysis, Multimodal Content Understanding, Instruction Decomposition, Content Refinement, Summarization & Generation, and Fidelity & Consistency Verification Agents, forming a closed-loop feedback mechanism for robust and finegrained document manipulation. \u2022 We demonstrate the superior performance of DocRefine on the.
Study Design
This work further contributes valuable token-level annotations for the SROIE dataset, thereby facilitating future research in multimodal sequence labeling for document analysis .
The DocRefine framework comprises six core, collaborative agents: the Layout & Structure Analysis Agent (LSA Agent), Multimodal Content Understanding Agent (MCU Agent), Instruction Decomposition Agent (IDA Agent), Content Refinement Agent (CRA Agent), Summarization & Generation Agent (SGA Agent), and Fidelity & Consistency Verification Agent (FCV Agent).
Results & Findings
Traditional document processing tools, while useful for basic text extraction and formatting, fall short when confronted with the inherent complexities of scientific documents, which often include intricate layouts, diverse figures, complex tables, mathematical formulas, and cross-references. However, directly applying these powerful models to endto-end complex document editing and refinement tasks still presents significant challenges, particularly regarding precision, content fidelity, and controllable generation, especially in scenarios demanding a harmonious understanding of.

Practical Applications
While LLM fine-tuning may offer marginal improvements, the core contribution often lies in optimizing multi-agent coordination and scaling agent numbers for signal control, with LLMs serving as an enhancement mechanism . This representation might include knowledge graph fragments, structured data tables (e.g., CSV from a table image), or even executable code snippets that capture the essence of the visual information, ready for manipulation by other agents.
Minor Layout Distortions, though less impactful, sometimes occur when complex structural changes are requested, indicating areas where the LSA Agent’s re-rendering logic could be further refined.
