PROBLEM TO BE SOLVED: To facilitate a grasp of corresponding steps.;SOLUTION: A first calculation unit 1c refers to step names of respective steps included in a first flow chart 2a and in a second flow chart 2b that are accepted by an input reception unit 1a, and calculating a similarity between each step name of the first flow chart 2a and each step name of the second flow chart 2b. A second calculation unit 1d calculates a relative position in the first flow chart 2a for each step included in the first flow chart 2a, and calculates a relative position in the second flow chart 2b for each step included in the second flow chart 2b. An identification unit 1e identifies a step included in the second flow chart 2b corresponding to any step included in the first flow chart 2a based on the similarity calculated by the first calculation unit 1c and the relative position calculated by the second calculation unit 1d.;COPYRIGHT: (C)2012,JPO&INPIT
