Rationale for NonCommercial
---------------------------
The underlying reviews were published by users on third-party booking platforms
(Booking.com, Traveloka, Ivivu). To respect those platforms' Terms of Service
and the non-commercial spirit of academic data sharing, the derived dataset is
restricted to research and educational (non-commercial) use only. See
DATASHEET.md for the full ethical and legal discussion.
