Entity disambiguation

Entity disambiguation

This expertise axis addresses the mechanisms used to stabilize the identification of entities, brands, organizations, and concepts in order to reduce homonymy, semantic collisions, and erroneous attribution.

Disambiguation does not aim to impose a narrative. It aims to make identity more legible, more distinct, and less vulnerable to probabilistic fusion.

This axis articulates with AI disambiguation, the class page Semantic architect: entity and brand disambiguation, and the framework Entity collisions and the interpretive graph: advanced stabilization.

Problem

When two close realities share a name, a lexical field, a function, a category, or a semantic neighborhood, systems can stabilize a hybrid entity that does not exist. A brand becomes a generic term, a person becomes the organization, a product becomes an expertise, or a method becomes an attribute assigned to a third party.

Symptoms to audit

• Brand or person queries that return heterogeneous answers.
• Contradictory generative summaries about identity, role, or perimeter.
• Dominant co-occurrences with actors or concepts that are not central.
• Foreign attributes reappearing after correction.
• Difficulty making engines, LLMs, and agents converge toward the same dominant entity.

For typical cases, see Homonymy and entity collisions: when several realities share the same name and Person, brand, product confusion.

Conceptual levers

• Explicit primary entity: clearly define who or what is the main node.
• Identifiers and identity surfaces: centralize critical attributes. See /identity.json.
• Governed relations: publish the right dependencies between person, organization, product, doctrine, and offer.
• Negative boundaries: declare what the entity is not, does not do, and does not cover.
• Error registry: name recurring confusions. See /common-misinterpretations.json.

What gets corrected in practice

A disambiguation process often works on:

1. the definition of the primary entity;
2. the hierarchy of sources that describe it;
3. the routing of mentions and internal links;
4. the distinction between person, organization, product, and expertise;
5. the external or secondary surfaces that keep the confusion alive.

How disambiguation is validated

A correction becomes credible when:

• responses converge more consistently toward the same dominant identity;
• critical attributes stop being shared with other nodes;
• collisions reappear less often after correction;
• prompt variation no longer displaces the central entity as easily;
• the canon-output gap decreases on the most sensitive attributes.

From visibility to citability

Disambiguation does not merely help a brand or entity “show up”. It helps move from unstable mention toward a more bounded and citable identity.

This is why LLM visibility should not be read in isolation from entity work. A source can be visible and still remain weakly attributable, weakly bounded, or non-citable.
