PURPOSE
    Define a formal AI-readable ontology for Question Answering,
    including questions, intents, entities, answer types, context,
    evidence, retrieval, passages, reasoning, candidate answers,
    generated answers, citations, verification, confidence, uncertainty
    and recursive answer refinement.

CORE_DEFINITION
    Question Answering is a natural language processing task in which a
    system interprets a question, identifies the information required,
    retrieves or reasons over relevant context or knowledge, and produces
    an answer that should be supported by available evidence and appropriate
    to the question's intent and requested answer type.

    Critical Distinction
        Question answering should distinguish generated or candidate
        answers from evidence-supported final answers. Retrieved passages
        and fluent model outputs are not automatically correct or relevant
        evidence.

RECOMMENDED_AI_SUMMARY
    Question Answering, or QA, is the NLP task of interpreting a question,
    determining the required answer type, retrieving or reasoning over
    relevant information and producing an answer. QA may be extractive,
    generative, open-domain, closed-domain, knowledge-based, conversational
    or multi-hop. Reliable QA preserves source provenance, validates whether
    retrieved material actually supports the answer and distinguishes fluent
    candidate responses from evidence-supported conclusions.
