Publication number: 20220083042Abstract: An information processing device includes a sufficiency determiner, a diagnostic unit, a request data generator, and a deliverer. The sufficiency determiner determines, concerning each diagnostic item in a target, whether plural pieces of inspection result data indicating inspection result by users, differing from a professional include sufficient pieces of effective inspection result data for diagnosing. The diagnostic unit diagnoses, concerning the diagnostic item, the condition of the target based on the plural inspection result data pieces when the plural inspection result data include sufficient pieces of inspection result data for diagnosing. The request data generator generates, concerning the diagnostic item, request data for requesting the users to conduct an inspection when the plural inspection result data pieces do not include sufficient pieces of inspection result data for diagnosing. The deliverer deliver the request data to user terminals.Type: ApplicationFiled: February 25, 2021Publication date: March 17, 2022Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Myungsook KO, Toshimitsu KUMAZAWA, Toru YANO
