The present invention discloses a state
machine based context-sensitive multi-round
dialog management system, comprising: an input module, for receiving multi-
modal input information from a user; an intention identification engine module, for identifying intention information in the multi-
modal input information; an intention module, for bringing multiple intention information identified by the intention identification engine module into one-to-one correspondence with multiple intention sub-modules at back ends; a state
machine module, comprising a plurality of state machines for managing a relevant context in the
dialog management system and providing support for an output result; an instruction
parsing engine module, comprising a plurality of instruction
parsing engine sub-modules for
parsing corresponding intention information and acquiring the parsed multiple intention information; and an output module, for acquiring policy information according to the results from the parsing engine module and the intention identification module, and transmitting the policy information to the state
machine module.
