US Patent 10977319 Expandable service architecture with configurable dialogue manager

Methods, systems, and computer programs are presented for facilitating user engagement with a bot. One example method includes receiving, by a dialogue manager server, a sequence specification for a user activity that identifies a type of interaction between a user and a network service, the sequence specification including instructions for implementing a trigger action in the event of a negative user input into the bot. The negative user input in the sequence of interactions is detected and the trigger action is implemented in response to detecting the negative user input.
