Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Across all main-study analyses, precision was consistently high (0.89–0.95) while recall was substantially lower (0.58–0.88), and confusion matrices showed models were more likely to extract inaccurate data than to claim information was not reported. → Schroeder 2025

Overall exact-match analysis in the main study across all 24 variables and 112 studies. "Precision was high (ranging from 0.90 - 0.93) while recall was substantially lower (ranging from 0.61 - 0.76)". The pattern of high precision and lower recall held across explicit and derived variables.
"Precision was high (ranging from 0.90 - 0.93) while recall was substantially lower (ranging from 0.61 - 0.76). The confusion matrices show that, generally speaking, models were more likely to extract inaccurate data rather than claim the information was not reported when it actually was."
Discussion¶
Related Claims¶
- LLMs are substantially less accurate at extracting and categorizing derived data based on predefined categories than at extracting explicitly stated data — related
- LLMs show moderate agreement with human coders when extracting explicitly stated data from education studies — related
- In zero-shot evaluation, GPT-4's multi-label classification results were similar to what might be expected of fine-tuned classifiers, with SetFit and GPT-3.5 showing contrasting precision/recall patterns — related
- LLMs are not ready to be used as primary data extraction tools without explicit human validation in education research synthesis — related
- Hint-based prompts raise ChatGPT scoring agreement with human experts to 98–100%, while no-hint prompts are unstable (Q2 precision 0.42) — related
