Frontier Tracker

A personal literature surveillance pipeline for tracking new papers from top journals (Nature, Science, Cell, PNAS families and beyond) using OpenAlex, Crossref, and Semantic Scholar APIs.

What it does

Frontier Tracker automates the weekly literature monitoring workflow:

1. Scan — Query OpenAlex for new papers from your configured journal watchlist
2. Enrich — Fill missing abstracts via three-way fallback (OpenAlex → Crossref → Semantic Scholar)
3. Screen — Classify papers into core / proxy / eco / noise tiers using your research profile keywords
4. Render — Output results as Excel dashboards, interactive HTML tables, Obsidian notes, or inline previews

No API keys required — uses public OpenAlex, Crossref, and Semantic Scholar endpoints.

Quick start

1. Clone and install

git clone https://github.com/yourusername/frontier-tracker.git
cd frontier-tracker
pip install openpyxl  # optional, for Excel output

2. Create your research profile

Copy the example profile and customize it:

cp references/example-profile.md references/my-profile.md
# Edit references/my-profile.md with your research keywords

See references/research-profile-template.md for the full template with all fields.

3. Build the journal watchlist

The default watchlist covers Nature, Science, Cell, PNAS families and related top journals:

python -X utf8 scripts/build_top_family_watchlist.py --format json --output state/watchlist.json

To also resolve OpenAlex source IDs (recommended for first run):

python -X utf8 scripts/build_top_family_watchlist.py --format json --resolve-openalex --output state/watchlist.json

4. Scan for new papers

python -X utf8 scripts/scan_recent_papers.py --days 7 --update-state --output outputs/data/frontier_scan_$(date +%Y-%m-%d).json

5. Enrich with abstracts

python -X utf8 scripts/enrich_abstracts.py \
  --input outputs/data/frontier_scan_$(date +%Y-%m-%d).json \
  --output outputs/data/frontier_enriched_$(date +%Y-%m-%d).json \
  --field new

6. Screen by your profile

python -X utf8 scripts/screen_by_profile.py \
  --input outputs/data/frontier_enriched_$(date +%Y-%m-%d).json \
  --profile references/my-profile.md \
  --output outputs/data/frontier_screened_$(date +%Y-%m-%d).json \
  --field both

7. Generate output

# Excel dashboard
python -X utf8 scripts/render_display_outputs.py --mode excel --scan-json outputs/data/frontier_screened_$(date +%Y-%m-%d).json

# Interactive HTML table
python -X utf8 scripts/render_display_outputs.py --mode app --scan-json outputs/data/frontier_screened_$(date +%Y-%m-%d).json

# Obsidian/Zotero notes
python -X utf8 scripts/render_display_outputs.py --mode notes --scan-json outputs/data/frontier_screened_$(date +%Y-%m-%d).json

# Quick inline preview
python -X utf8 scripts/render_display_outputs.py --mode codex --scan-json outputs/data/frontier_screened_$(date +%Y-%m-%d).json

One-command weekly report

python -X utf8 scripts/auto_weekly_report.py \
  --input outputs/data/frontier_enriched_$(date +%Y-%m-%d).json \
  --profile references/my-profile.md

Configuration

Research profile

Your profile controls which papers are classified as core, proxy, or noise. Create it at references/<name>.md with these sections:

• Core keywords — Directly on-topic (classified as "core")
• Proxy keywords — Adjacent methods/themes (classified as "proxy")
• Eco-context keywords — Broader context (classified as "eco")

See references/example-profile.md for examples.

Journal watchlist

Edit references/top-journal-families.md to customize which journals to track. The file uses markdown tables organized by pool:

• flagship-general-full-track — Nature, Science, Cell, PNAS
• top-family-full-track — High-signal family journals
• top-family-relevant-only — Broad journals (filtered by relevance)

Adding CAS/JCR rankings

If you have CAS or JCR ranking data, you can enrich the watchlist:

1. Add ranking columns to your watchlist
2. Use full-track for CAS Zone 1-2 or JCR Q1
3. Use relevant-only for CAS Zone 3-4 or JCR Q2-Q4

Chinese journal supplement

Always use python -X utf8 on Windows to avoid encoding errors with non-ASCII characters in journal names and paper titles.
