On the other hand, the chatbot replies to the input information IN11 in the form of a question by the user Ux with the content, "Are you hospitalized for more than 5 consecutive days?"
- the information processing device 100 executes an accumulation process of accumulating a dialogue history based on the answer (step S17).
- the information processing device 100 executes an update process to update the knowledge database 122 based on the interaction history (step S18).
- the interaction history is analyzed, and based on the analysis results, feedback is provided that meta information for determining whether or not to present question information to the user is linked to the knowledge graph KG1. It will be done.
- the information processing device 100 selects omitted question information that does not need to be presented because it is obvious what kind of answer the user Ux will answer, out of a series of candidate question information to be presented to the user Ux. Determined based on dialogue history. Then, the information processing apparatus 100 presents only the question information other than the question information to be omitted to the user Ux. As a result, the information processing device 100 can improve the efficiency of interaction with the user Ux.
