AI POWERS

AI and verification glossary

Understand recurring terms in answers and guides with short definitions, examples and references that help you avoid common confusions.

Before citing a source
  1. Open the original document: a title or search snippet is insufficient.
  2. Match author, date, scope and exact passage to the claim.
  3. Keep publication date separate from the date you consulted the document.
  4. Preserve units, exceptions and limitations; a reliable portal does not validate every inference.

Prompt

A request given to AI, including goal, relevant context and constraints.

Example : “Compare these options by cost, time and maintenance.”

Context

Information available to interpret a request; it is not automatically lasting memory.

Example : Repeat relevant details in a new question on AI POWERS.

Hallucination

Generated content that sounds plausible but is false or unsupported.

Example : A complete-looking reference may not correspond to a real document.

RAG

A method that retrieves documents and provides passages to generation.

Example : Check that the retrieved passage actually supports the answer.

Bias

A tendency that can distort representation, measurement or decisions.

Example : Compare controlled variants without generalising from a single result.

Provenance

Documented origin and history of an object, document or dataset.

Example : Keep producer, original publication, licence and transformations.

DOI

Persistent object identifier; it does not certify quality.

Example : Check title and authors after following the identifier.

Anonymisation

Transformation intended to make identifying a person practically impossible.

Example : Removing a name alone may be insufficient.

Pseudonymisation

Replacing direct identifiers while additional information can reconnect records.

Example : A customer number may still link to a person.

Alternative text

Text equivalent suited to an image’s function in context.

Example : A chart needs its information, not just its colours.

Confidence interval

Interval accompanying an estimate and a stated coverage procedure.

Example : Keep the stated level; it is not a range of every individual value.

Version

Identified state of software, a document or rules.

Example : Record the version tested to reproduce a comparison.

Large language model (LLM)

Model trained on language data with many parameters.

Example : It can produce fluent text without guaranteeing truth.

Personal data

Information about a person identifiable directly or through combined details.

Example : Combined details may identify someone without stating their name.

Primary source

Document directly related to the subject; its status depends on the question.

Example : A contemporary diary is evidence to examine, not neutral truth.

Percentage point

Arithmetic difference between two values expressed as percentages.

Example : From 20% to 25%: +5 points, but a 25% relative increase.

Prompt injection

An attempt to divert an AI system using malicious instructions, directly or within content it reads.

Example : A document to summarise asks to ignore the task and send data: treat the passage as suspicious content, not permission.

AI system evaluation

Documented examination of a system against defined tasks and criteria. Quality depends on its use context and is not just fluent wording.

Example : Test ordinary, ambiguous and unanswerable requests; record failures and repeat the same cases after a change.
