<P>PROBLEM TO BE SOLVED: To provide a data generation apparatus for generating data suitable for analysis of factors of time variation. <P>SOLUTION: The data generation apparatus includes: an input unit 101 for inputting input data having identification information, an event, and an occurrence date of the event in association with each other; an event time series generation unit 102 for generating an event time series in which events are arranged in order of occurrence date; a state time series generation unit 103 for generating a state time series representing transition of state of an object following occurrence of events included in the event time series; a partial time series generation unit 104 for extracting a time series including a plurality of states matching a state transition pattern from the state time series and generating a partial state time series having the extracted time series in association with identification information corresponding to the state time series; and an attribute value time series generation unit 106 for acquiring attribute information corresponding to the identification information from an attribute value storage unit 125 and generating an attribute time series having the acquired attribute information in association with each of states included in the partial state time series. <P>COPYRIGHT: (C)2010,JPO&INPIT |
