PURPOSE: To provide a method and device for document information classification which classify a document group without depending upon a prescribed classification system by using a key word given to the document group or a word appearing in a document and rearranges classification results hierarchically. CONSTITUTION: A data management part 101 manages the document group in a document DB 107 and a group of key words, given to respective documents, in a key word DB 108. A document classification part 103 classifies the documents on the basis of the individual key words and stores them in folders. Then, folders having similar document groups are integrated. For the integration, it is judged whether the integration is effective or not. It is judged whether or not further classifications can be made in folders that are left without being integrated, thereby generating a hierarchical classification system. The classification results are outputted on a CRT 109 by a classification output part 104 to provide an environment wherein a user can read the classification results out.
