The paper introduces the Semantic‑Empirical Updating Framework (SEUF), which uses large language model paraphrases and embeddings aligned with hypothesized item‑factor assignments to create prespecified priors for Bayesian confirmatory factor analysis. In experiments with a 38‑item survey and two public surveys (FEVS and RIASEC), SEUF maintained semantic structure after wording controls and achieved comparable loading precision with 50 respondents to conventional CFA with 70–82 respondents, reducing required sample size by 29–39%. The approach yielded lower loading errors and better credible‑interval coverage, especially when respondent data were scarce, demonstrating the benefit of incorporating semantic priors in small‑sample measurement.

The paper introduces the latent space item response model (LSIRM) as a tool for uncovering how language models differ on specific benchmark items. By mapping 1,348 models across 5,761 BBH items and comparing scoring methods across BBH, GPQA, MMLU-Pro, and MuSR, the authors show that items with similar correct answers cluster together, especially when scored by option labels. LSIRM separates a model’s tendency to perform better on certain answer categories from other performance differences, revealing that small changes in scoring can dramatically alter model rankings.
