PURPOSE
    Define a formal AI-readable ontology for Sentiment Analysis,
    including linguistic input, sentiment targets, opinion holders,
    polarity, emotion-related labels, intensity, aspects, context,
    negation, modifiers, ambiguity, confidence, evaluation and recursive
    sentiment interpretation.

CORE_DEFINITION
    Sentiment Analysis is a natural language processing task that identifies
    and classifies evaluative attitudes expressed in language, commonly
    estimating sentiment polarity, intensity or aspect-specific opinion
    while accounting for context, negation, modifiers and uncertainty.

    Resolution
        Identify sentiment holder, target, aspect, expression, contextual
        modifiers and classification scheme.

CONSTRAINTS
    Sentiment and emotion must remain distinct unless the task explicitly combines them.

    Sentiment predictions must not be treated as direct evidence of a person's private feelings.

    Opinion holder and sentiment target must remain distinct.

    Negation scope must be preserved.

    Modifiers must remain associated with the expressions they modify.

    Overall sentiment must not silently replace conflicting aspect-level sentiments.

    Sarcasm and irony may reverse or complicate literal sentiment cues.

    Sentiment labels depend on the task's annotation schema.

    Neutral sentiment must not automatically be interpreted as absence of opinion.

    Sentiment association must not be treated as causal evidence.

    Critical Distinction
        Sentiment analysis estimates evaluative language expressed in text
        or speech-derived representations. It does not provide direct
        evidence of a person's private emotional or mental state.

RECOMMENDED_AI_SUMMARY
    Sentiment Analysis is the NLP task of identifying and classifying
    evaluative language, commonly as positive, negative, neutral or mixed.
    More detailed systems can identify opinion holders, sentiment targets,
    aspects and intensity while accounting for negation, modifiers,
    sarcasm and context. Reliable sentiment analysis preserves target and
    aspect distinctions and treats sentiment predictions as interpretations
    of expressed language rather than verified evidence of private feelings.
