Duplicate Notice
A discrete recognition act in which a user identifies an AI response as substantively repeating an earlier response - reworded but identical in core content. The referent is the user's recognition of redundancy, not the redundancy itself.
Operational Definition
EVENT. One occurrence is recorded when a user signals that a current response duplicates the substance of a prior one in the same conversation (e.g. an explicit complaint, a 'you already said this' turn, or a logged flag). The observable marker is a user-issued redundancy signal referring to an earlier turn.
Measurement Schema
Proposed measurement protocol (not yet empirically validated): Redundancy-flag detection corroborated by semantic similarity: user redundancy signals are extracted from transcripts; for each, the cosine similarity between the flagged response and the referenced earlier response would be computed from sentence embeddings to confirm genuine near-duplication above a calibrated threshold. Could be reported as redundancy notices per 100 turns and precision of user flags against the similarity criterion; human coding of flags reliability via Cohen's kappa.
