ABSTRACT:
A document classifying system is formed by a document data classifying system, a document classifying function building system, a sample data storage apparatus and a keyword storage apparatus. The document data classifying system inputs document data and defines a classification to which the document data belongs. The document classifying function building system is operatively connected to the document data classifying system and automatically builds a classification decision tree in the document data classifying system. A sample data storage apparatus is operatively connected to the document classifying function building system and stores sample data formed by a set comprised of the document data and the classification to which the document data belongs. The keyword storage apparatus is operatively connected to the document classifying function building system and stores keywords extracted thereby.
