METHOD FOR CONSTRUCTING DATA CLASSIFICATION SYSTEM

摘要

PURPOSE: A method for constructing a data classification system is provided to change a classification system structure in an information processing device easily and effectively by responding to a classification system structure variation. CONSTITUTION: A basic dimension vector is decided by extracting a plurality of keywords out of a plurality of sample objects possessed in a set of a predetermined group. A basic classification item is created according to each object group, and a classification item rule of each basic classification item is decided using a weight value dimension vector embodying a weight value in each keyword of the basic dimension vector according to the basic classification items. A parent classification item related to at least one basic classification item is created. A classification item rule of the parent classification item is decided using classification item rules allocated to the basic classification item and a generalization Boolean operator(S134). A child classification item related to a basic classification item is created. A classification item rule of the child classification item is decided using classification item rules allocated to the basic classification item and a fragmenting Boolean operator. A weight value dimension vector is calculated with respect to new object. The weight value dimension vector assigns the object in classification items adapted to a classification item rule.
