For example, let’s assume a customer sends the message "I’d like to make a reservation for two for the weekend" to The Orange Hotel. Thanks to assets, it is possible to parse and extract important information such as date, number of guests, and the action in this message. For Dialogflow to understand this message and return the correct response to the customer, you need to define different entities in terms of service type, date, and the number of guests. The @service-type that is created in this example determines the reservation action, @sys.date the weekend, and @sys.number the number of guests.
