AstroMLab/USAAAO_QA

USA Astronomy and Astrophysics Organization (USAAAO) Open-ended Questionaire

This dataset contains structured question–answer pairs from the USAAAO (2017-2019), converted from pdf to LaTeX sources, into a machine-readable JSONL format.

The dataset includes:

• Short, medium, and long-form astrophysics problems
• Multi-part questions (grouped via parent_id)
• Full worked solutions
• Associated figures (JPEG images) where applicable

The goal of this dataset is to support evaluation and benchmarking of large language models (LLMs) on:

• Advanced scientific reasoning
• Mathematical derivation
• Multi-step physics problem solving
• Multimodal reasoning (text + figures)

---

Dataset Structure

Each record contains:

• id – unique question or sub-question identifier
• parent_id – shared ID for multi-part questions (null for single-part)
• year – exam year
• part – sub-part label (e.g., "a", "b")
• part_order – ordering index for sub-parts
• question_type – typically "open-ended"
• question_length – "short", "medium", or "long"
• question – problem statement
• answer – full solution text
• image – relative path to image (if applicable)
• caption – figure caption (if applicable)
