PROBLEM TO BE SOLVED: To enable comparison between frequent flow lines to be quantitatively performed and thereby enable the analysis of a movement locus to be more appropriately performed.SOLUTION: A partial character string frequently occurring in a set of movement loci is extracted as a frequent flow line by a frequency flow line extraction unit 22, and a frequency flow line graph in which, each of the extracted frequent flow lines being made to be a node, frequent flow lines including a common character or character string are connected node to node by an edge by a frequent flow line graph creation unit 23. Then, display data in which each of the extracted frequent flow lines are arranged at coordinates in a three-dimensional space on the basis of dissimilarity between the frequent flow lines is generated by a display data generation unit 24, and display data in which the created frequent flow line graph is arranged at coordinates in a two-dimensional or three-dimensional space on the basis of dissimilarity between each node thereof is generated. These items of display data are transmitted from a transmission control unit 26 to a business operator terminal PC and displayed. |
