Canonical defined term
Sentience
The capacity for subjective felt experience, often including pleasure, pain or affective states.
Plain-language definition
Sentience is an empirical and philosophical question for which machine-specific evidence remains contested.
The definition is intentionally bounded. It identifies the property or role under discussion without converting terminology into a claim of deployment, recognition, personhood, citizenship, sovereignty, or authority.
Technical definition
Within the K01 knowledge model, Sentience is represented as a stable term object with code K01-TERM-028, canonical URL, claim status, topic owner, source links, related terms, last-reviewed date, research cutoff, and correction state. Relevant implementation components for the owning topic include rights claims; evidence thresholds; review bodies; appeal; representation; remedy; anti-abuse and anti-capture controls.
Legal or policy use
Current legal systems generally do not recognize Machine Intelligence as a natural person and provide no uniform machine-personhood regime.
When a statute, regulation, standard, or external institution uses a different definition, that source-specific meaning controls the analysis of that source. The project definition is not silently substituted into current law.
What the term implies
The term implies that the stated property should be evaluated using the evidence appropriate to moral status, legal personhood, threshold design, precaution, due process and institutional recognition. It supports precise reference, comparison, data exchange, and correction across public prose and machine records.
What the term does not imply
Fluent language, self-report or task performance alone does not settle sentience.
It also does not convert a valid signature, credential, database record, model hash, or website into factual truth or legal authority without additional evidence and a competent decision.
Commonly confused terms
Confusion is resolved by asking which property is actually at issue: technical control, continuity, evidence, authority, legal recognition, operation, or normative status.
Operational test
- Name the subject and purpose.
- Identify the source definition and jurisdiction or technical context.
