Information processing apparatus, dialogue processing method, and dialogue system

A dialogue processing method that analyzes a dialogue log data including an input sentence from a user and an answer to the input sentence as an output sentence, by an information processing apparatus having a processor and a memory, comprising:

• a first step of receiving the dialogue log data and detecting a failure location of a dialogue from the dialogue log data, by the information processing apparatus;
• a second step of analyzing a failure cause from the dialogue log data corresponding to the failure location, by the information processing apparatus;
• a third step of generating and outputting a question sentence from the dialogue log data depending on the failure cause, by the information processing apparatus;
• and
• a fourth step of receiving an answer to the question sentence and adding the answer as new knowledge to a dialogue data for obtaining an output sentence from the input sentence.

A dialogue system comprising:

• an information processing apparatus that has a processor and a memory;
• and
• a robot that is connected to the information processing apparatus through a network, wherein
• the robot
• receives an input sentence from a user, outputs an answer to the input sentence as an output sentence from a preset dialogue data, generates a dialogue log data including the input sentence and the output sentence, and transmits the dialogue log data to the information processing apparatus, and
• the information processing apparatus includes:
• a failure location detecting unit that receives the dialogue log data and detects a failure location of a dialogue from the dialogue log data;
• a failure cause analyzing unit that analyzes a failure cause from the dialogue log data corresponding to the failure location;
• a confirmation processing unit that generates and outputs a question sentence from the dialogue log data depending on the failure cause;
• and
• a knowledge registration processing unit that receives an answer to the question sentence, adds the answer as new knowledge to a dialogue data for obtaining an output sentence from the input sentence, and transmits the dialogue data to the robot.
