Interactive processing device and interactive processing system

An interactive processing device configured to acquire information of one or more items for performing a predetermined operation through an interaction with a user, the interactive processing device comprising:

• one or more hardware processors configured to function as:
• one or more itemized processing units corresponding to the one or more items, respectively;
• and
• an interaction control unit configured to control the interaction with the user collaboratively with the one or more itemized processing units, wherein
• the interaction control unit transmits input information corresponding to an input from the user to each of the one or more itemized processing units,
• each of the one or more itemized processing units extracts a candidate for information that is to be acquired by the each itemized processing unit from the input information received from the interaction control unit, and transmits the extracted candidate to the interaction control unit together with information indicating that the extracted candidate is the information that is to be acquired,
• the interaction control unit
• determines, among a plurality of candidates received from each of the one or more itemized processing units, a candidate for which the information indicating that the candidate is the information that is to be acquired satisfies a first threshold as information of an item corresponding to the itemized processing unit that has transmitted the candidate for which the information indicating that the candidate is the information that is to be acquired satisfies the first threshold, and
• when there is an item of undetermined information, outputs a response for inquiring the information of the item to the user, and
• each of the one or more itemized processing units has a rule for extracting the candidate and deriving the information indicating that the candidate is the information that is to be acquired based on interactive knowledge corresponding to a type of the information that is to be acquired, each of the one or more itemized processing units being implemented with an item name of a corresponding item and information determining an operation of the each itemized processing unit being given.
