PURPOSE
    Define a formal AI-readable ontology for Semantics in natural language
    processing, including linguistic expressions, meanings, concepts,
    entities, predicates, arguments, relations, senses, references,
    semantic roles, propositions, compositionality, ambiguity, context,
    entailment and recursive meaning interpretation.

CORE_DEFINITION
    Semantics is the study and computational representation of meaning in
    linguistic expressions, including how words, phrases, clauses and
    sentences refer to entities, express concepts, predicates, relations
    and propositions, and combine to produce interpretable meaning.

    Resolution
        Identify expressions, candidate meanings, entities, predicates,

CONSTRAINTS
    Semantics and syntax must remain distinct.

    Semantics and pragmatics must remain distinct.

    Words and word senses must remain distinguishable.

    Mentions and real-world entities must remain distinct until reference is resolved.

    Predicate and argument roles must be preserved.

    Relation direction must be preserved where directional.

    Semantic similarity must not automatically be treated as logical equivalence.

    Semantic relatedness must not automatically be treated as factual identity.

    Multiple meanings must remain represented when ambiguity is unresolved.

    Linguistic meaning alone does not establish factual truth of a proposition.

    IF
        Semantic Role R is supported for Argument A
    THEN

            R to A

    IF

    IF
        Meaning of larger expression follows from meanings and composition rule

    Critical Distinction
        Semantics represents linguistic meaning rather than grammatical
        structure or pragmatic use. A proposition can be semantically
        well-formed and interpretable without being factually true.

RECOMMENDED_AI_SUMMARY
    Semantics is the representation and analysis of meaning in language.
    In natural language processing it models concepts, entities,
    predicates, arguments, relations, word senses, references, semantic
    roles and propositions. Semantic interpretation combines lexical
    meanings with syntactic structure and context while preserving
    ambiguity where necessary. Semantic similarity or meaningfulness does
    not by itself establish logical equivalence, factual identity or truth.
