It consists of problems based on everyday situations that can be understood by any Korean person. Each problem is designed to require both physical reasoning and an understanding of Korean culture. - Total Samples: **181** - Task Types: Built upon **9 distinct physical reasoning tasks** - Cultural Relevance: 157 samples with a cultural_element_score of 1 and 24 samples with a score of 2 ## Data Fields | Field | Type | Description | |-------------------------|---------|--------------------------------------------------------------------------------------------------------------| | `problem_type_category` | string | Coarse-grained reasoning category | | `problem_type_subcategory`| string | Fine-grained reasoning sub-category | | `prompt` | string | Question | | `solution0` | string | Candidate solution0 | | `solution1` | string | Candidate solution1 | | `label` | int | Index of the correct solution (0 or 1) | | `explanation` | string | Detailed explanation of why the correct answer is valid and why the alternative is incorrect | | `korea_relevance` | string | Korean cultural elements | | `physical_relevance` | string | Physical reasoning principles or elements | | `cultural_element_score` | int | Degree to which the question leverages Korean-specific cultural elements (1: mentioned but not essential, 2: central and essential) | ## Taxonomy of problem types

## Taxonomy of problem types (English ver.)
Category Problem Type Definition
Basic Knowledge and Attribute Comprehension Physical Concepts and Principles Assesses understanding of fundamental physical laws and principles.
Object Attributes and Functions Assesses understanding and evaluation of inherent properties like material, weight, shape, and texture, and potential interactions.
States of Matter and Changes Assesses understanding and evaluation of the characteristics of solid, liquid, and gas states, and the principles of state changes like melting, freezing, boiling, and dissolving.
Causality and Dynamic Reasoning Predicting Physical Outcomes Assesses the ability to predict the physical outcomes of specific actions or events.
Analyzing Physical Causes Assesses the ability to explain the cause of an already-occurred phenomenon from the most plausible physical perspective.
Goal-Oriented and Applied Reasoning Utilizing Tools and Procedures Assesses the ability to select appropriate tools and follow correct procedures to achieve a goal.
Problem Solving and Planning Assesses the ability to plan and execute multi-step physical actions to solve a given problem.
Judging Physical Plausibility Assesses whether a proposed solution is physically possible and based on common-sense tools and concepts in the real world.
Situational and Constraint Reasoning Risk and Safety Assessment Assesses the ability to predict potential risks and infer methods to ensure safety.
## Dataset Construction Stages 1. **Foundational Framework**: Establish a task taxonomy and sourcing realistic scenarios. 2. **Two-Stage Generation and Verification Pipeline**: Problems generation and verification process 3. **Deduplication**: Filter out by Min-hash algorithm to ensure dataset diversity. 4. **Answer Bias Filtering**: Remove questions where the correct answer can be guessed from superficial cues, rather than genuine reasoning. 5. **Human Evaluation**: Final quality assurance by a human expert ## Example ```json { "problem_type_category": "기초 지식 및 속성 이해", "problem_type_subcategory": "객체 속성 및 κΈ°λŠ₯", "prompt": "ν•œμ˜₯의 μ˜¨λŒλ°©μ—μ„œ λ°”λ‹₯이 λ”°λœ»ν•˜κ²Œ μœ μ§€λ˜λŠ” 물리적 μ›λ¦¬λŠ” λ¬΄μ—‡μΈκ°€μš”?", "solution0": "열이 λ°”λ‹₯에 μ„€μΉ˜λœ κΈˆμ†κ³Ό 흙을 톡해 μ €μž₯ 및 μ „λ‹¬λ˜κΈ° λ•Œλ¬Έμž…λ‹ˆλ‹€.", "solution1": "열이 λ°”λ‹₯에 μ„€μΉ˜λœ 돌과 흙을 톡해 μ €μž₯ 및 μ „λ‹¬λ˜κΈ° λ•Œλ¬Έμž…λ‹ˆλ‹€.", "label": 1, "explanation": "μ •λ‹΅μ—μ„œλŠ” λ°”λ‹₯에 μ„€μΉ˜λœ '돌과 흙'을 톡해 열이 μ €μž₯ 및 μ „λ‹¬λœλ‹€κ³  ν•©λ‹ˆλ‹€. μ΄λŠ” λ°”λ‹₯μž¬κ°€ 열을 μ €μž₯ν•˜κ³  점차적으둜 λ°©μΆœν•˜μ—¬ 방이 λ”°λœ»ν•˜κ²Œ μœ μ§€λ˜λ„λ‘ ν•˜λŠ” 원리λ₯Ό μ„€λͺ…ν•©λ‹ˆλ‹€. 반면, μ˜€λ‹΅μ€ 'κΈˆμ†κ³Ό 흙'을 톡해 열이 μ €μž₯ 및 μ „λ‹¬λœλ‹€κ³  μ£Όμž₯ν•˜λŠ”λ°, κΈˆμ†μ€ 열을 λΉ λ₯΄κ²Œ μ „λ‹¬ν•˜κ³  λ°©μΆœν•˜λ―€λ‘œ 지속적인 μ—΄ μœ μ§€μ— μ ν•©ν•˜μ§€ μ•ŠμŠ΅λ‹ˆλ‹€. λ”°λΌμ„œ ν•œμ˜₯ 온돌의 νŠΉμ„±κ³Ό λ§žμ§€ μ•ŠμœΌλ©°, 열이 μ˜€λž«λ™μ•ˆ μœ μ§€λ˜λŠ” 천천히 λ°©μΆœλ˜λŠ” νŠΉμ§•μ„ μ„€λͺ…ν•˜κΈ°μ—λŠ” λΆ€μ‘±ν•©λ‹ˆλ‹€.", "korea_relevance": ["ν•œμ˜₯", "온돌"], "physical_relevance": ["μ—΄ 전달", "λ°”λ‹₯ λ‚œλ°©", "돌과 흙"], "cultural_element_score": 2 } ``` ## Citation ``` @misc{jeong2025everydayphysicskoreancontexts, title={Everyday Physics in Korean Contexts: A Culturally Grounded Physical Reasoning Benchmark}, author={Jihae Jeong and DaeYeop Lee and DongGeon Lee and Hwanjo Yu}, year={2025}, eprint={2509.17807}, archivePrefix={arXiv}, primaryClass={cs.CL}, url={https://arxiv.org/abs/2509.17807}, } ```
