DATA ANALYSIS METHOD AND DATA ANALYSIS SYSTEM

PROBLEM TO BE SOLVED: To provide a method and system for extracting, on condition that the disturbance of the appearance order of data is allowed, a time series pattern from a data series including information showing the relationship of order. SOLUTION: When partial time series patterns at a tail end are matched with each other and the types of items appearing before the partial time series patterns are matched with each other among the partial time series patterns, the partial time series patterns are regarded as one group and are extracted by: frequent item pattern extraction processing appearing before the partial time series pattern; time series pattern group preparation processing using the frequent item patterns; and time series pattern deriving processing (S503) belonging to the time series pattern group using the frequent item pattern.
