Missing Schema Glue Forces AI Overviews to Hybridize Distinct Knowledge Graph Entities

AI Overviews suffer entity resolution failures when an established canonical hub goes dormant.

Dr. Kimberly R. Harris observes that in a December 2025 incident, Google's systems hybridized Canadian musician Ashley MacIsaac's Freebase and Wikidata Knowledge Graph entity with an entirely unrelated record.

The algorithmic hallucination triggered fallout, resulting in a canceled concert and a subsequent May 2026 lawsuit.

The hybridization occurred despite the entity possessing decades of press coverage and historical Wikipedia data.

The system merged the profiles because MacIsaac's official website had sat untouched for about 12 months and completely lacked the connective schema markup required to link external identifiers.

When a canonical hub leaves an information vacuum, real-time query expansion models do not stop processing.

Instead, the algorithm synthetically infers relationships at scale under time pressure.
