The paper introduces Table Graph Reasoner (TabGR), a model that represents tables as an Attributed Table Graph (ATG) to preserve row-column-cell structure and enable graph-based reasoning without task-specific training. It also proposes a Question-Guided Personalized PageRank (QG-PPR) mechanism to rerank tabular data and address the lost-in-the-middle issue. Experiments on multiple table reasoning benchmarks show that TabGR outperforms state-of-the-art models by up to 9.7% in accuracy.

MERIT‑Rank is a reranking framework that integrates multiple reasoning trajectories to enhance text ranking robustness. It introduces a Multi‑Trajectory Reasoning Space (MTRS) to evaluate query‑document relevance from diverse perspectives and a joint reranker that consolidates these paths into a single ranking decision. The Progressive Rank Policy Optimization (PRPO) training scheme stabilizes reasoning trajectories and progressively improves ranking quality, yielding superior performance on both reasoning‑intensive and traditional retrieval benchmarks, with a 4B model outperforming larger 7B and 32B rerankers on BRIGHT.
