Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: First question information includes questions about a predetermined subject, and each piece of first answer information, associated with a piece of the first question information, indicates an answer that is responsive to the question indicated by the piece of the first question information. The apparatus updates conversion parameters including correlation values each indicating a degree of a correlation between keywords included in the first question information and the first answer information, by adjusting the correlation values so that the keywords enable a predetermined degree of predicted reliability to search for the first answer information. Upon receiving a new question not included in the first question information, the apparatus determines, based on the updated conversion parameters and first keywords extracted from the new question, second keywords enabling the predetermined degree of predicted reliability, and searches for an answer that is responsive to the new question by using the second keywords.
