Intent labels in this sample are mocked — a deterministic keyword stub, not LLM output — applied to review title + text (n = 956). 318 reviews with no clear intent signal are excluded from the four categories.

Expanding beyond binary sentiment polarity, each customer submission is parsed using a standardized intent-classification matrix to isolate specific consumer behavioral drivers. Over the trailing 12-month period, Praise indicators — including verified positive experiences, explicit repurchase intent, and brand advocacy signals — constitute the dominant intent segment, accounting for 48% of all reviews (458 reviews). Conversely, critical Complaint signals register at 13% (123 reviews), establishing the baseline operational risk margin.
