Pdf Rename

PDF Rename — Academic Paper Organizer

Rename academic PDFs to: [Year] [Venue] Title.pdf

Three-stage pipeline:

Extract → Verify → Rename

Anti-error principle: Never re-parse PDF content during Rename. The Manifest is the single source of truth.

Quick Start

# Stage 1: Extract raw text → manifest.json
python scripts/extract.py ""

# Stage 2: LLM parses raw_text → inject verified data → manifest_verified.json
#   (Agent reads manifest.json raw_text field and writes to scripts/VERIFIED_DATA_*.py)
python scripts/apply_verified.py ""

# Stage 3: Preview / Execute
python scripts/execute.py "" --preview
python scripts/execute.py "" --execute

Stage 1: Extract

What it does:

• Reads first 3 pages of each PDF
• Stores raw text in manifest.json → raw_text field
• Extracts year_hint from filename prefix
• Detects potential duplicates by filename similarity

Manifest schema — see references/manifest_spec.md

Stage 2: Verify

The agent reads manifest.json, parses each raw_text field, and writes verified metadata.

Steps:

1. Read manifest.json
2. For each entry, parse the raw_text to extract: title, authors, venue, year, abstract
3. Create or update scripts/VERIFIED_DATA_*.py with verified entries

VERIFIED_DATA format:

VERIFIED_DATA = {
    "OriginalFilename.pdf": {
        "title": "Correct Paper Title",
        "year": "2024",
        "venue": "NeurIPS",
        "confirmed": True   # must be True to be renamed
    },
}

Rules:

• Key must exactly match the original filename
• confirmed: True → status becomes ready → will be renamed
• confirmed: False or omitted → skipped
• Multiple VERIFIED_DATA_*.py files are auto-merged
• Prefer venue/conference year over filename year (e.g., arXiv 2022 → NeurIPS 2024)

⚠️ Key gotchas during parsing:

• Multi-line titles: pypdf concatenates lines without spaces (e.g., "Direct score maximization outperformsplanning loss") — use context to infer correct split
• Journal refs at top of page: "Math. Program. (2012) 133..." is NOT the title — read further
• arXiv papers: use conference year if published, otherwise use arXiv year
• Non-paper files (book chapters, lecture notes, loss curves): set confirmed: False and skip

Then run:

python scripts/apply_verified.py ""

---

Stage 3: Rename

• Only status == 'ready' files are renamed
• Duplicate titles → (1), (2) suffixes
• Backup created at /_backup_YYYYMMDD_HHMMSS/

python scripts/execute.py "" --preview   # dry run
python scripts/execute.py "" --execute   # rename
