A slot is a location in an utterance that the bot can identify and map to entities, such as rooms, nights, dates, or other variables. For example, the bot might identify “two executive rooms for three nights” as a slot when an agent says, “I would like to book two executive rooms for three nights starting tomorrow.” Slots can be mapped using built-in or custom slot types. To create a custom slot type, select the Custom Slot Type option on the Slots tab. A name should be provided, and the slot type should be specified as a regular expression.
