PROBLEM TO BE SOLVED: To provide a relevant class extracting method capable of preventing omission of classification code attachment at the time of classification code attaching operation or omission of a retrieval range at the time of retrieving operation and improving the quality and efficiency of classification code attaching operation/retrieving operation. SOLUTION: Attachment inclinations of "class already attached to documents", "retrieving logs" and "class already attached to related documents already attached to documents" are analyzed and pairs of class deeply related to each other and their feature keywords are previously extracted and class information related to a sort specified by a user is extracted and reported. On the other hand, a keyword is extracted from a document to be processed, the extracted keyword is collated with the feature keywords of the sort pairs, its similarity is calculated, and the extracted related sort information is sorted and reported.
