摘要
In order to determine an abnormal degree of a production facility on the basis of log data, a learning unit 44 learns the classification rule that classifies whether the production facility is normal or abnormal from a text feature amount on the basis of the text feature amount (for example, first main component and second main component) obtained from a number of texts included in a plurality of pieces of log data obtained in a predetermined process of the production facility and production history information of the production facility, an extraction unit 46 extracts a text feature amount of the log data to be monitored obtained in the predetermined process of the production facility, and a determination unit 48 determines whether the production facility is normal or abnormal when the log data to be monitored is obtained on the basis of the extracted text feature amount and a classification rule.
