Abstract:
A method for analyzing sets of temporal data, each data set of temporal data comprising a plurality of records collected at a time period unique to each said set, each record having a plurality of data items, said method comprising the steps of:creating data association rules for at least a plurality of sequential sets, each association rule representing data records having at least some common data items, determining the confidence factor for each such association, storing said association rules and said confidence factors for said at least a plurality of sequential data sets in data partitions, comparing said confidence factors for each association rule a selected data partition with the corresponding confidence factors for at least one other data partition, generating an output signal whenever the change of confidence factor for said selected data set varies from the corresponding confidence factor for said at least one other data set exceeds a selected threshold value.
