Match on identifiers and controlled keys, not on display names, or your join silently splits and duplicates entities.\n\n## Procedure\n\n1. Prefer an authoritative identifier over any name string: company → LEI or CIK; paper → DOI; researcher → ORCID; place → ISO 3166 \u002F GeoNames id; person → national id where lawful; product → GTIN.\n2. Normalise the fallback key: Unicode NFKC, casefold, strip legal suffixes (`Inc`, `Ltd`, `GmbH`, `Co`), collapse punctuation, expand common abbreviations (`Corp` → `Corporation`).\n3. Build candidate pairs by blocking on a cheap key (first token, country, first author), never all-pairs.\n4. Score candidates with string similarity, then set a two-threshold policy:\n   - score ≥ 0.92 → auto-merge\n   - 0.75 ≤ score \u003C 0.92 → human-queue\n   - below 0.75 → not the same\n   ```python\n   from difflib import SequenceMatcher\n   s = SequenceMatcher(None, norm(a), norm(b)).ratio()\n   ```\n5. Resolve, don't delete. Assign a canonical id and keep every alias; a mapping table (`alias → canonical_id`) beats overwriting rows.\n6. Handle one-to-many and many-to-one: an acquired subsidiary and its parent, a paper with two versions, a person with two affiliations.\n7. Record unresolved entities as their own cluster and report their count — do not force-merge them.\n\n```bash\n# gather all distinct spellings before matching\ncut -d, -f2 entities.csv | sort | uniq -c | sort -rn | head -30\n```\n\n## Pitfalls\n\n- Fuzzy-matching on names alone merges distinct people (\"J. Smith\") and splits variants (\"Jon\", \"Jonathan\").\n- The same name across languages (\"Apple\" vs \"苹果\") needs a cross-lingual link table, not string distance.\n- Identifiers can be recycled or reassigned; check the id's validity date when sources span years.\n- A shared address or phone is weak evidence — shell companies and families share them.\n- Merging then joining loses the ability to audit; always keep the alias map.\n\n## Verification\n\n    python3 -c \"import pandas as pd; print(pd.read_csv('alias_map.csv').canonical_id.nunique(), 'canonical entities')\"\n\nReport: \"1,204 raw name strings resolved to 817 canonical entities via LEI (93%) + similarity; 41 borderline pairs queued for review; 0 force-merges.\"\n","# Resolve Entities Across Sources\n\nThe same real-world entity appears as \"Apple\", \"Apple Inc.\", \"AAPL\", and \"苹果\" across sources.
