Publication number: 20210209316Abstract: An agent system includes a first memory and a first processor coupled to the first memory. The first processor analyzes contents of a verbal question, and caries out pre-processing that replaces vocabulary, which is used in the contents of the question, with homogenized vocabulary, and generates response information based on results of analysis. In a case in which there exists substitution vocabulary that has replaced original vocabulary in the pre-processing, the first processor changes the response information such that it can be recognized that the substitution vocabulary in the response information is synonymous with the original vocabulary, and outputs the response information.Type: ApplicationFiled: November 12, 2020Publication date: July 8, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Chikage KUBO, Keiko NAKANO, Eiichi MAEDA, Hiroyuki NISHIZAWA

Publication number: 20210193129Abstract: In cases in which a confidence score of an inferred intent label is a predetermined threshold or less, an intent inference section searches for whether or not wording pertaining to a location, such as “on the door”, is present in a question. In cases in which a word relating to a location is present, the intent inference section consults individual function identification data associated with OM item codes in order to find intent labels including individual functions relevant to the location (such as “door”). In cases in which an intent label including an individual function relevant to the “door” is found, an OMA interaction control section consults QA data to find and acquire associated response information based on the found intent label and the OM item code, and notifies a HMI interaction control section of such response information.Type: ApplicationFiled: November 30, 2020Publication date: June 24, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Chikage KUBO, Keiko NAKANO, Eiichi MAEDA, Hiroyuki NISHIZAWA
