DeepReview: Improving LLM-based Paper Review with Human-like Deep Thinking Process
Revolutionizing Peer Review with LLM-Powered Deep Thinking
Large Language Models (LLMs) are increasingly used for automated paper review, but face challenges like limited domain expertise, hallucinated reasoning, and lack of structured evaluation. DeepReview introduces a multi-stage framework designed to emulate expert reviewers through structured analysis, literature retrieval, and evidence-based argumentation. DeepReviewer-14B, trained on the DeepReview-13K dataset, significantly outperforms baselines, achieving win rates of 88.21% against GPT-01 and 80.20% against DeepSeek-R1. This work sets a new benchmark for robust LLM-based paper review.

DeepReview: A Multi-Stage Reasoning Framework
DeepReview emulates expert reviewers through a structured multi-stage framework:
- Novelty Verification (z1): Assesses research originality through question generation, paper analysis, and literature review. It leverages tools like OpenScholar and ReRank models for comprehensive context.
- Multi-dimension Review (z2): Synthesizes insights from multiple perspectives, transforming author rebuttals into constructive suggestions. Key principles include maintaining technical depth, providing actionable feedback, and preserving a professional tone.
- Reliability Verification (z3): Ensures assessment accuracy through systematic evidence analysis, utilizing a four-stage verification chain (methodology, experimental, comprehensive analysis) to assign confidence levels and generate an integrated Meta-Review.
- Quality Control Mechanism: A rigorous automated quality control process verifies logical consistency and completeness of generated samples, removing inconsistent or incomplete data to maintain high quality in the DeepReview-13K dataset.
Unprecedented Performance in Paper Review
DeepReviewer-14B demonstrates superior performance across various metrics. Compared to prompt-based baselines, it achieves an average 65.83% reduction in Rating MSE and a 15.2% improvement in Decision Accuracy. Against strong finetuned baselines like CycleReviewer-70B, it reduces Rating MSE by 44.80% and improves Ranking Spearman correlation by 6.04%.
In LLM-as-a-judge evaluations, DeepReviewer-14B achieves impressive win rates of 88.21% against GPT-01 and 80.20% against DeepSeek-R1, highlighting its human-like assessment quality.
For fine-grained assessments, DeepReviewer-14B excels in Soundness (0.1578 MSE, 0.3029 MAE on ICLR 2024), Presentation, and Contribution, demonstrating a balanced and strong performance across all critical dimensions of review.
Robustness Against Attacks & Flexible Scalability
DeepReviewer exhibits strong resilience to adversarial attacks. Under attack, its overall rating increases by only 0.31 points, significantly less than other models which show dramatic increases (e.g., Gemini-2.0-Flash-Thinking by 4.26 points). This robustness is attributed to its multi-stage reasoning framework, which focuses on intrinsic paper quality over malicious prompts.
The model offers unique Test-Time Scaling capabilities through two mechanisms: Reasoning Path Scaling (Fast, Standard, Best modes with increasing analytical depth and token lengths) and Reviewer Scaling (adjusting the number of simulated reviewers from R=1 to R=6). This allows users to balance efficiency and response quality, with the "Fast" mode still outperforming CycleReviewer (6000 tokens) with only half the output tokens (3000).
Navigating Ethical Considerations
The development of DeepReviewer involves critical ethical considerations such as bias amplification, deskilling of human reviewers, and potential erosion of transparency. To mitigate these harms, DeepReviewer employs a multi-faceted approach:
- Rigorously Designed Dataset: DeepReview-13K is synthetically generated to model expert reasoning and incorporate diverse perspectives, minimizing unintended biases.
- Decision Support Tool: DeepReviewer is intended to augment human expertise, not replace it, advocating for a human-in-the-loop approach.
- Open-Source & User Guidelines: Releasing DeepReviewer as an open-source resource with comprehensive guidelines to caution against over-reliance and emphasize human oversight.
- Bias Auditing & Benchmarking: Ongoing evaluation across diverse datasets to identify and refine areas for improvement.
This proactive stance aims to ensure DeepReviewer's ethical and beneficial application in scientific peer review.
DeepReviewer-14B demonstrates exceptional comparative performance, significantly outperforming GPT-01 in LLM-as-a-judge evaluations, validating its superior human-like assessment capabilities.
Enterprise Process Flow: DeepReview Multi-Stage Reasoning
| Metric | DeepReviewer-14B | CycleReviewer-70B | GPT-01 | DeepSeek-R1 |
|---|---|---|---|---|
| Rating MSE ↓ | 1.3137 | 2.4870 | 4.3414 | 4.1648 |
| Decision Accuracy ↑ | 0.6406 | 0.6304 | 0.4500 | 0.5248 |
| Rating Spearman ↑ | 0.3559 | 0.3356 | 0.2621 | 0.3256 |
| Pairwise Rating Accuracy ↑ | 0.6242 | 0.6160 | 0.5881 | 0.6206 |
DeepReviewer demonstrates superior robustness against adversarial attacks, with an average rating increase of only 0.31 points under attack. This resilience stems from its multi-stage reasoning framework which prioritizes intrinsic paper quality checks.
DeepReviewer's Test-Time Scalability
DeepReviewer introduces unique test-time scaling capabilities through Reasoning Path Scaling and Reviewer Scaling. Reasoning Path Scaling offers Fast, Standard, and Best modes, progressively deepening analysis and increasing output token lengths (approx. 3,000, 8,000, and 14,500 tokens respectively). This leads to steady improvements across metrics, with Rating Spearman correlation increasing by 8.97% from Fast to Best mode.
Reviewer Scaling emulates collaborative review by adjusting the number of simulated reviewers from R=1 to R=6, enhancing score aggregation through multiple viewpoints. Both methods validate that increased computational investment enhances the model's paper assessment capabilities, offering flexibility to balance efficiency and quality.
Test-Time Scaling in DeepReviewer significantly enhances performance, with a nearly 9% improvement in Rating Spearman correlation when transitioning from Fast to Best reasoning modes, demonstrating the value of deeper analysis.
Addressing Limitations and Future Work
Key limitations of DeepReviewer include its reliance on a synthetic dataset (DeepReview-13K), which, despite rigorous design, may not fully capture the complexities of human review. The "Best" inference mode, while thorough, can be computationally intensive, though this is mitigated by "Fast" and "Standard" modes.
Furthermore, while the model shows robustness against adversarial attacks, complete immunity is not yet achieved, indicating a need for ongoing research into enhancing security and reliability. Future work will focus on incorporating adversarial samples during training to improve resilience.
