Chinese Competitive Debating Dataset and Benchmark

Read the original on arXiv AI →

The paper introduces a Chinese competitive debating dataset and benchmark, comprising 148 fully adjudicated matches with 2,698 stages and 20,542 exchange units, all annotated by 120 professional judges using a shared rubric. It offers manually verified transcripts, segmentation, and preserved scores, votes, and rationales, enabling evaluation of large language models on winner-tendency prediction, stage-score prediction, and best-debater prediction. Zero‑shot experiments show the best models achieve 66.2% winner‑prediction accuracy, a 0.250 Pearson correlation for stage scores, and 56.8% best‑debater accuracy.

Evaluating Language Models in Realistic Conversational Contexts

The paper introduces UPHELD, a large benchmark of human-to-human dialogues written by professional script writers, featuring realistic turn densities and over 36,000 per-turn human annotations. It evaluates existing automatic metrics and LLM-as-a-judge methods, finding them unreliable against expert human judgment. Using UPHELD, the authors develop a Mixture-of-Judges framework that improves correlation with human assessments by about 30%.

Toward Robust LLM-Based Judges: Taxonomic Bias Evaluation and Debiasing Optimization

The paper introduces JudgeBiasBench, a benchmark that systematically quantifies judgment biases in large language model (LLM)-based judges across four dimensions and 12 bias types. It evaluates both generative and discriminative judges, revealing significant bias patterns that undermine reliability. The authors propose bias-aware training—reinforcement learning for generative judges and contrastive learning for discriminative judges—to reduce these biases while maintaining evaluation performance.
