Abstract: A dialogue system including a processor, a memory, an audio input apparatus, an audio output apparatus, a touch input apparatus, and a display unit. The processor receives an input from the voice or a touch input apparatus, analyzes the content of the input, and selects a scenario corresponding to the input data from preset scenario information. The processor generates the output data specified in the scenario, calculates the priority of the input data, and determines the presence or absence of the scenario being prepared for the output data. When there is the scenario under generating the output data, the processor changes the output method of the scenario to be executed based on the priority.

Abstract: An optimization system includes: a customer touring acquisition unit that is configured to be able to acquire touring of stores by a customer; a store attribute information acquisition unit that is configured to be able to acquire one or more items of store attribute information for classifying features of the stores; a model training unit that creates a correlation model for the touring by the customer and the store attribute information by using the touring of the stores by the customer and the store attribute information as inputs; and a trained model storage unit that stores the created model, in which information regarding one or more stores to be opened is presented in such a way as to increase the touring of the stores by the customer based on the model.
