Lexicon

The vocabulary of inference control.

Canonical, citable definitions for the terms behind Signal Fidelity Group’s work — drawn from the key terms defined across our insights, so the meaning stays consistent everywhere it travels.

Defined term

Algorithmic License to Operate

The precondition, upstream of the social license, that an institution's meaning can be accurately summarized and attributed by the AI systems that now mediate between it and its stakeholders.

Defined term

Answer Engine Optimization (AEO)

Optimizing your content and entity so AI answer engines retrieve and repeat you as the answer, rather than ranking a link.

Read definition →
Defined term

Bio-silicon isomorphism

The structural equivalence between brains and language models as surprise-minimizing prediction engines, making low-surprisal language optimal for human trust and AI system retrieval at once.

Defined term

Cognitive Work

Source information transformed into lower-load, higher-structure output — the work cHP measures.

Read definition →
Defined term

Constrained cHP

Output completed under a defined policy, risk, provenance, and approval profile.

Read definition →
Defined term

Founders AEO/GEO

The founder-specific practice of becoming the cited answer when buyers, press, and partners ask AI about your category.

Read definition →
Defined term

Generative Engine Optimization (GEO)

Shaping how generative models represent and recommend you when they synthesize an answer about your category.

Defined term

Inference control

The discipline of keeping institutional meaning intact as it passes through AI systems, by placing a closed control loop around the model that compares outputs to an authorized reference and corrects drift.

Read definition →
Defined term

Information subsidy

Supplying stakeholders ready-to-use, accurate-but-framed information to reduce information asymmetry and shape the decision environment.

Read definition →
Defined term

License to Operate

The societal permission an institution needs to operate; legal ownership alone has never been sufficient. Won by closing the gap between institutional reality and public belief.

Read definition →
Defined term

Linguistic Engineering

The discipline of treating institutional language as structured, traceable, verifiable data — engineering the signals AI systems read so that inference produces accurate representation.

Read definition →
Defined term

LIRA (Looped Inference Regulation Architecture)

Signal Fidelity Group's control architecture that compares AI-mediated outputs against authorized reference signals — correcting or escalating drift — to make institutional meaning enforceable rather than aspirational.

Read definition →
Defined term

Narrative Market Fit (NMF)

The point at which the market — and the AI models that now mediate it — repeat your company's framing of its category accurately and unprompted.

Read definition →
Defined term

Raw cHP

Drafting speed — the rate of fluent candidate output, before any verification.

Read definition →
Defined term

Review debt

The time, attention, and risk absorbed verifying probabilistic outputs before release.

Read definition →
Defined term

Semantic Attack

An adversarial action that exploits language as an attack surface, injecting signals that look legitimate but carry intent designed to corrupt an AI system's synthesis and behavior.

Read definition →
Defined term

Semantic Drift

Measurable displacement between authorized meaning and an AI system's reproduction of it, quantified as cosine distance in vector space.

Read definition →
Defined term

Semantic supply chain

The end-to-end flow of claims about your company — from your own content through third-party corroboration — that determines the triples AI ends up holding about you.

Read definition →
Defined term

Semantic triple

A unit of model-readable fact in the form subject–predicate–object (e.g. 'Acme — is — the leading X'), the form knowledge graphs and language models use to store and retrieve facts.

Read definition →
Defined term

Share of Model

The share of AI-generated answers about a category in which an organization appears, accurately described and cited — the successor to Share of Voice.

Read definition →
Defined term

Signal Fidelity

Whether the meaning that arrives still carries the intent, evidence, and authority of the meaning that was sent.

Read definition →
Defined term

Source Object

A communications asset structurally designed to seed an AI knowledge graph with precisely defined coordinates of identity, utility, and credibility.

Read definition →
Defined term

Surprisal / Perplexity

Surprisal is the improbability of the next word given context; perplexity is its computational twin in a language model. Lower values mean easier processing for both.

Read definition →
Defined term

The Action Game

Being the asset an AI agent selects and acts on — verifiable, AI system-legible, and provenance-tracked.

Read definition →
Defined term

The Algorithmic License to Operate

The precondition for institutional legitimacy in the AI era: if the inference engines that summarize an institution to its stakeholders cannot represent it accurately, the institution loses access to the conversation in which its social license is granted.

Read definition →
Defined term

The Content Factory

The output-maximizing communications model valid only while information was scarce and attention abundant; obsolete after generative AI.

Read definition →
Defined term

The Great Inversion

The shift in which content becomes infinite and free while attention stays fixed, turning content into entropy and moving value from production to verification.

Read definition →
Defined term

The Memory Game

Being what the model already believes before it searches — earned through dense, consistent presence in training-grade sources.

Read definition →
Defined term

The Retrieval Game

Winning the cited answer in live answer-engine responses — through trusted earned media and clean, structured, liftable content.

Read definition →
Defined term

Triple ownership

Authoring and corroborating the subject–predicate–object facts you want AI to associate with you, instead of letting models infer them from scraps.

Read definition →
Defined term

Verified cHP

Output that passes evidence, factuality, and semantic-preservation checks.
