| "rai:dataLimitations": "The dataset is German-only and may conflate mathematical reasoning with German-language competence. OCR and image extraction may introduce artifacts not present for original contest participants. Public historical contest materials may have appeared in model training data. The dataset is not recommended for grading students, making individual educational decisions, or replacing human exam calibration data.", |
| "rai:dataBiases": "The benchmark reflects the style, curriculum assumptions, and participation context of the German Mathematical Kangaroo competition. It may overrepresent visual-spatial contest problems and German school-mathematics conventions relative to broader mathematical reasoning or other student populations.", |
| "rai:personalSensitiveInformation": "The dataset contains contest problems and aggregate metadata only. It does not contain personal information about participants.", |
| "rai:dataUseCases": "Intended uses include evaluating LLMs and vision-language models on German multimodal school mathematics, contest-faithful scoring, abstention behavior, and exam-level human-model comparison. Validity has been established only for benchmark-style model evaluation in this contest setting, not for human assessment or student-level decisions.", |
| "rai:dataSocialImpact": "The dataset can broaden multilingual and multimodal evaluation beyond English text-only benchmarks. A key risk is overinterpreting high model scores as evidence of human-like reasoning or stable exam-equating ability; the accompanying analysis explicitly cautions against that use.", |
