Entity Decoder

Entity Decoder: Scope

This page describes the Entity Decoder, a web application of the Grounding Page Project, available at groundingpage.com/tool/entity-decoder/. It does not describe the Grounding Page Project as a whole, the Grounding Page Standard, or other analysis tools with similar names. The Entity Decoder was previously released under the name "Entity Analysis Tool".

Entity Decoder: Lead Definition

The Entity Decoder is a web application that analyzes whether a brand, person or product is reliably recognizable for AI systems. It produces a Grounding Readiness Score from 0 to 100, separates model knowledge from grounding contribution, classifies the entity according to the Grounding Page Ontology V2 and proposes a tailored set of Grounding Pages.

Entity Decoder: Purpose and Use

The Entity Decoder answers a single question for any brand, person, product or organization: Is this entity already clear enough for AI systems, or does it need additional grounding?

It is used to assess AI visibility, to identify gaps in entity definition, to plan Grounding Pages and to monitor whether grounding work has actually changed how an entity is perceived by AI systems.

Entity Decoder: Functions

Grounding Readiness Score

For every analyzed entity the Entity Decoder produces a Grounding Readiness Score from 0 to 100. The score expresses how clearly the entity can be identified and stably classified by AI systems.

Model Knowledge vs. Grounding Contribution

The Entity Decoder separates the AI Score into two components: Model Knowledge (what the model already knows on its own, without external grounding) and Grounding Contribution (the additional clarity gained when public web sources are taken into account). The two values always reconcile mathematically with the displayed AI Score.

Knowledge Origin

Each result is classified by knowledge origin: Self-Sufficient (the model alone is enough), Hybrid (model and grounding work together) or Grounding-Dependent (the entity is essentially invisible without grounding).

Entity Classification

Every entity is assigned to one of 18 entity classes from the Grounding Page Ontology V2 (e.g. Organization, Person, Product, Place, Tool or Platform, Standard, Event, Project).

Stability and Ambiguity Analysis

The Entity Decoder evaluates whether the entity is stably understood (Stability), whether competing meanings exist (Ambiguity) and how reliably it can be disambiguated by additional context (Disambiguation Strength).

Dual-State Stability

For every entity the Entity Decoder shows two stability states side by side: how stable the entity is without grounding (model only) and with grounding (with public web sources). This makes the actual effect of grounding directly visible.

Hallucination Risk

Each analysis includes a hallucination risk indicator that flags when an entity is likely to be confused, mixed up with other entities or invented by AI systems.

Diagnostic Variables

The Entity Decoder derives diagnostic variables such as Update Need, Grounding Necessity, Grounding Purpose and Primary Weakness. They explain why an entity scores the way it does, not just what the score is.

Interpretation Layer

Every result is summarized in a short, plain-language interpretation that names the central insight, the dominant weakness and the next concrete step. The interpretation is grounded in the same numerical analysis shown in the result page.

Recommended Grounding Pages

For every analysis the Entity Decoder generates a tailored Grounding Page blueprint: a small number of clusters with concrete page titles, each describing the entity in a clearly defined context. The titles can be used directly as final page titles for new Grounding Pages.

Source Evidence Layer

Before scoring, the Entity Decoder collects independent evidence about the entity from public web sources. This evidence is used to validate the input, detect ambiguity and ground the analysis in real-world signals.

Result Structure

Every analysis is delivered as a structured result page with: AI Score and label, Model Knowledge and Grounding Strength tiles, Score-Origin connection line, Interpretation block, Stability dashboard, Recommended Grounding Pages and a list of related entities.

PDF Export

Every analysis can be exported as a PDF report with the full result set, including AI Score, sub-scores, interpretation, stability dashboard and the recommended Grounding Page structure.

Entity Decoder: Score Reconciliation

A key property of the Entity Decoder is that the displayed scores always add up. Model Knowledge plus Grounding Contribution always equals the AI Score; their sum can never exceed 100. Whenever a calculation would otherwise produce an inconsistent breakdown, the Entity Decoder reduces the AI Score, not the displayed contribution. This guarantees that users see a coherent and verifiable calculation in every analysis.

Entity Decoder: Score Classification

Very High

85 to 100 — the entity is very clearly recognizable for AI systems.

High

70 to 84 — the entity is well recognizable for AI systems.

Medium

50 to 69 — the entity is only partially recognizable for AI systems.

Low

0 to 49 — the entity is not yet reliably recognizable for AI systems.

Entity Decoder: Frequently Asked Questions

What is the Entity Decoder?

The Entity Decoder is a web application that analyzes whether a brand, person or product is reliably recognizable for AI systems. It produces a Grounding Readiness Score from 0 to 100, separates model knowledge from grounding contribution and proposes a tailored set of Grounding Pages.

What does the Grounding Readiness Score measure?

The Grounding Readiness Score expresses on a scale from 0 to 100 how clearly an entity can be identified by AI systems. The Entity Decoder splits this score into Model Knowledge (what the model already knows on its own) and Grounding Contribution (the additional clarity gained when public web sources are taken into account). The two values always reconcile to the displayed AI Score and their sum can never exceed 100.

Which entity classes does the Entity Decoder recognize?

The Entity Decoder recognizes 18 entity classes from the Grounding Page Ontology V2: Organization, Person, Group or Role, Product, Service, Tool or Platform, Feature, Segment, Field of Knowledge, Concept, Publication, Dataset, Standard, Method, Place, Event, Metric and Project.

What are the recommended Grounding Pages?

For every analysis the Entity Decoder generates a tailored Grounding Page blueprint: a small number of clusters with concrete page titles, each describing the entity in a clearly defined context. The entity is always the central focus. The titles can be used directly as final page titles for new Grounding Pages.

Is the Entity Decoder free to use?

The Entity Decoder is free to use. It is available as an open web application without registration or login at groundingpage.com/tool/entity-decoder/.

What is the relationship between the Entity Decoder and the Grounding Page Standard?

The Entity Decoder is the practical tool inside the Grounding Page Project. It uses the Grounding Page Ontology V2 as the basis for entity classification and produces Grounding Page blueprints that follow the Grounding Page Standard.

Was the Entity Decoder previously called something else?

Yes. Until April 2026 the Entity Decoder was called "Entity Analysis Tool" (German: "Entitäts-Analyse Tool"). The functionality is the same and was significantly extended; only the name and the URL changed. The old URLs redirect permanently to the new ones.

Entity Decoder: Not Identical With

Grounding Readiness Score (Feature)

Entity Class: Feature. Domain: Scoring. Key Difference: The Grounding Readiness Score is an output value of the Entity Decoder, not a standalone tool. Separation Reason: A score is a metric inside a tool, not a system with its own execution logic.

Grounding Page Standard (Standard)

Entity Class: Standard. Domain: Specification. Key Difference: The Grounding Page Standard defines the format for fact pages. The Entity Decoder is a tool that builds on the ontology within this standard. Separation Reason: A standard is a specification, not an executable system.

Grounding Page Project (Project)

Entity Class: Project. Domain: Organization. Key Difference: The Grounding Page Project is the umbrella initiative that includes the standard, the website and the tool. The Entity Decoder is one specific tool within this project. Separation Reason: A project is an organizational frame, not a software system.

Entity Resolution (Method)

Entity Class: Method. Domain: NLP, data integration. Key Difference: Entity Resolution is a method for matching different data records to the same entity. The Entity Decoder analyzes the AI grounding readiness of an entity but does not perform record-level matching. Separation Reason: A method is a reproducible procedure, not a software system with its own user interface.
