Comprehensive Person Profile Enrichment via Linkup Web Search
This script enriches person profiles with ALL discoverable data from web sources,
with FULL PROVENANCE for every claim. No data is stored without a verifiable source.
Rule Compliance:
- Rule 6: WebObservation Claims MUST Have XPath Provenance (adapted for web search)
- Rule 21: Data Fabrication is Strictly Prohibited
- Rule 26: Person Data Provenance - Web Claims for Staff Information
- Rule 34: Linkup is the Preferred Web Scraper
- Rule 35: Provenance Statements MUST Have Dual Timestamps
Data Extracted (when available):
- Birth date/year
- Birth location
- Education history
- Career milestones
- Publications
- Awards/honors
- Professional affiliations
- Death date (if applicable)
Usage:
python scripts/enrich_person_comprehensive.py --limit N [--dry-run]
