ReViewGraph predicts accept/reject outcomes from full papers by simulating reviewer-author exchanges and encoding opinions and their relations in a typed graph for a trained graph classifier. On the ICLR 2025 test set, it achieves Macro F1 71.65, versus 59.26 for CycleReviewer-70B. This is a benchmark result, not evidence of improved real-world peer review.

Key insights

  • Explicitly modeling multi-round reviewer-author debates and their argumentative relations within a structured graph is essential for capturing nuanced dynamics and improving the accuracy of automated review decisions.
  • The heterogeneous nature of the debate graph, with distinct node and edge types, allows for more semantically expressive representations of review interactions, which enhances decision-making and interpretability.
  • Superior performance and generalizability can be achieved in automated peer review by leveraging structured graph reasoning over LLM-generated debate content, effectively bypassing the need for intensive LLM parameter updates.
