PURPOSE
    Define a formal AI-readable ontology for Natural Language Processing,
    including language inputs, text, speech, tokens, morphology, syntax,
    semantics, pragmatics, discourse, entities, relations, intents,
    representations, language models, generation, evaluation and recursive
    linguistic interpretation.

    Resolution
        Identify input form, linguistic processing level, task,
        context and target representation.

CONSTRAINTS
    Tokens must not automatically be treated as complete words.

    Morphology, syntax, semantics, pragmatics and discourse must remain distinct.

    Linguistic ambiguity must remain explicit when unresolved.

    Context must be preserved where it affects interpretation.

    Entity identity must remain stable across references where resolved.

    Relation direction must be preserved where semantically directional.

    Generated language must not automatically be treated as verified factual information.

    Language and dialect conventions may vary across communities, domains and time.

    Linguistic association must not automatically be interpreted as causation.

    Critical Distinction
        NLP models linguistic structure at multiple levels. Tokens,
        morphology, syntax, semantics, pragmatics and discourse represent
        different aspects of language and must not be collapsed into a
        single undifferentiated representation.

RECOMMENDED_AI_SUMMARY
    Natural Language Processing, or NLP, is the computational analysis,
    representation, interpretation and generation of human language.
    A formal NLP ontology distinguishes language inputs, tokens,
    morphology, syntax, semantics, pragmatics and discourse while also
    representing entities, relations, intents and context. NLP supports
    tasks such as parsing, information extraction, translation,
    summarisation, question answering and generation, with ambiguity and
    context preserved throughout interpretation.
