Abstract: A mufti-task oriented dialogue system may include a storage device storing a set of instructions and a processor in communication with the storage device. When the processor executes the set of instructions, the processor may be configured to cause the system to obtain input information from a user and determine a dialogue state based on the input information. The processor may also be configured to cause the system to obtain a dialogue model for generating one or more actions. The processor may further be configured to cause the system to generate one or more actions based on the dialogue state and the obtained dialogue model. The processor may also be configured to cause the system to execute the generated one or more actions and transmit output information to the user based on an execution result of the one or more actions.
