OTA reviews become AI recommendation source, Huake CSI draws attention

On October 22, 2026, TravelDaily China reported that hotel reviews are becoming an important source for large-model assistants such as Doubao when recommending hotels; the AI scrapes and summarizes real reviews from various platforms, paying particular attention to negative reviews. The report mentioned that the Huake CSI is calculated based on OTA review opinions from the past 90 days, on a 100-point scale, and consists of an NPS sentiment score (weight 70%) and an opinion volume score (weight 30%). The report also said that hotels with sparse reviews or low CSI may disappear entirely from AI answers. This report is currently the latest development on the matter, and no follow-up reports have disclosed further details.
