<p>The present invention provides a time-series data analysis device whereby it is possible to estimate the cause of occurrence of information in time-series data even if the information does not have periodicity. The time-series data analysis device is provided with: a time-series data acquisition unit (11) which obtains time-series data; a determination rule storage unit (12) which stores a determination rule comprising targeted data identification information identifying targeted data included in the time-series data, occurrence pattern information specifying conditions for occurrence patterns for the targeted data, and cause information indicating the cause of occurrence of the targeted data; a targeted data extraction unit (13) which extracts targeted data, as identified by the targeted data identification information, from time-series data; an occurrence pattern determination unit (14) which determines whether the occurrence pattern of the extracted targeted data matches the occurrence pattern information; and a cause estimation unit (15) which estimates the cause of occurrence of the extracted targeted data on the basis of the cause information if the occurrence pattern of the extracted targeted data is determined to match the occurrence pattern information.</p> |
