ABSTRACT:
A service provider registers information of some documents, including an identifier of each document and a bibliographic item constituting the document content, in a storage section in a database section and determines classifications to which these documents should belong to further register identifiers of these documents to the classification items in the storage section. A calculation section calculates a distinction quantity of each classification item by consulting the bibliographic item of the classified document in the database section. Another calculation section calculates a distinction quantity of an unclassified document in the database section, and a decision section determines and classifies a classification item to which the unclassified document should belong based on a result of the calculation and the distinction quantity of each classification item. A collection section periodically collects a new document or an updated document from the network environment, and a classification information extraction section registers classification in the database in accordance with the classification item specification written in the document.
