Record structure

Each row is one paper. sections is a list of objects — one per section:

{
  "paper_id": "arxiv:2401.00123v2",
  "arxiv_id": "2401.00123",
  "arxiv_version": 2,
  "title": "...",
  "abstract": "...",
  "authors": ["Author A", "Author B"],
  "arxiv_categories": ["quant-ph"],
  "primary_category": "quant-ph",
  "full_text": "Introduction text\n\nMethod text\n\n...",
  "sections": [
    {"section_type": "BACKGROUND", "section_title": "1. Introduction", "text": "..."},
    {"section_type": "METHOD",     "section_title": "2. Methods",      "text": "..."},
    {"section_type": "RESULTS",    "section_title": "3. Results",      "text": "..."}
  ]
}

Usage

from datasets import load_dataset

ds = load_dataset("konsman/physics-corpus", "quantum-physics", split="train")

for paper in ds:
    print(paper["paper_id"], paper["primary_category"])
    for sec in paper["sections"]:
        print(sec["section_type"], sec["section_title"], sec["text"][:80])
