Abstract
A document storage stores a plurality of documents belonging to a certain field. The administrator of a host device uses a classification attribute selector to select the types of attributes suitable for classifying the documents stored in the document storage, from the types of attributes which are stored in a candidate storage and can be used as classification keys, and stores the selected types of attributes in a classification attribute storage. An attribute analyzer analyzes each of documents retrieved by a document retriever to determine which one of the types of attributes stored in the classification attribute storage an attribute element contained in the document belongs to. An attribute classifier classifies each of the retrieved documents into a category according to the type of the attribute element contained in the document based on the determined type of an attribute from the attribute analyzer.
