ABSTRACT:
The invention makes it possible to avoid an increase in the number of confirmation sentences and response sentences output to the user which gives dissatisfaction for the user by the increase that occur due to recognition errors. The present invention provides a device for determining the content of the request input by the user and the information types that can be provided to the user; a device for generating a dialogue sequence that includes confirmation for the user for each information type and a dialogue sequence that does not carry out confirmation; a device for calculating the dialogue cost of each dialogue sequence; a device for calculating the optimal dialogue cost for each of the information types, a device for calculating the next most optimal dialogue cost in the case that each of the attributes of the content of the request is first confirmed; a device for calculating the loss due to the confirmation of the attributes from the difference therebetween, a device for calculating the expected loss due to the confirmation of the attributes taking into consideration the probability of the information type, and a device for prioritizing and confirming the attributes whose expected loss is minimal.
