PROBLEM TO BE SOLVED: To automatically visualize relevance between sentences or importance of each the sentence. SOLUTION: A rough classification generation means 3 sequentially generates a deformation DT matrix 24 by repeatedly executing clustering processing, and outputs at least information related to the sentence constituting a cluster in each the cluster on the deformation DT matrix 24 as rough classification data 25. A display processing means 16 screen-displays a result of rough classification by a tree structure using a cluster symbol showing each the cluster generated by each the clustering processing on the basis of the rough classification data 25 and a link symbol showing integrated relation between the respective clusters.
