PROBLEM TO BE SOLVED: To make work for moving the categories efficient while making support so that each category of a hierarchical structure of categories can be moved according to a user's intention, and to appropriately reconstruct the structure of the categories in accordance with a user's moving operation. SOLUTION: A word vector generation unit 31 of a document classification unit 3 performs word vector generation processing of documents, word vector generation processing of documents in the categories, and word vector generation processing in the categories. A classification/clustering unit 32 performs classification/clustering processing of the documents. A moving category candidate presentation unit 41 of a category editing unit 4 presents categories to be candidates of moving operations. A moving category re-classification unit 42 performs the re-classification so that at least one of the document included in the categories differing from the moved categories and the different categories becomes an appropriate classification form. A moving category name change unit 43 changes the names of the moved categories after the re-classification. COPYRIGHT: (C)2010,JPO&INPIT
