Expedia Group™️ acts as a booking agent for all sorts of travel. An issue we’ve wrestled with is when a hotel (or vacation rental, activity, etc.) shares public contact information through our platform that allows for direct booking. This act violates our service agreements, and we must detect if it happens. Furthermore, this mechanism needs to scale to review an ongoing stream of data generated by bookings, website updates, client updates, etc.
This is not a unique problem in the travel industry. It can be generalized to verify a whole class of financial and legal agreements on an ongoing basis. Speed is of the essence; quickly detecting violations protects the platform’s viability and stops possible fraud.
