IDEAlign: Comparing Ideas of Large Language Models to Domain Expert

IDEAlign introduces a new protocol for evaluating the similarity of large language model (LLM) annotations to expert judgments. It uses pick‑the‑odd‑one‑out tasks to capture expert similarity and benchmarks various similarity methods—including text embeddings, topic models, and LLM-as-a-judge—against these human ratings. Applied to educational datasets, the study finds that most metrics miss nuanced expert dimensions, with LLM-as-a-judge performing best yet still insufficient for full expert alignment.

Experts Rise Where LLMs Disagree: Using Cross-Model Disagreement to Target Expert Effort in LLM Codebook Revision for Large-Scale Annotation

The paper proposes using large language models (LLMs) to identify disagreements among models as a way to focus expert effort on revising codebooks for large‑scale text annotation. Three expert feedback methods are evaluated: editing LLM‑generated revisions (Codebook Verifying), answering questions about disagreements (Question Answering), and labeling disagreement cases with rationales (Rationale Labeling). Experiments on tutoring‑session transcripts show that Rationale Labeling achieves the highest LLM‑labeling accuracy (64.9%) compared to the expert‑revised codebook (57.8%), with Question Answering also outperforming the baseline (60.5%).

MERIT: Matching Expertise via Rubric-Informed Training for Reviewer Assignment

MERIT is a two‑stage framework for reviewer assignment that first trains a reviewer assessor using reinforcement learning to match paper‑specific expertise rubrics with reviewers’ prior work, guided by an LLM judge. The assessor’s predictions are then distilled into an embedding‑based retriever for efficient large‑scale assignment. Experiments show the 4B assessor outperforms larger general‑purpose LLMs on suitability classification, and the retriever achieves state‑of‑the‑art performance on LR‑Bench and the CMU Gold dataset.
