The document processing device 100 extracts a word from a document 210 to be inspected before processing, calculates the identity of the word and adaptation of the class identity information in the document 210 to be inspected before processing for each of the plurality of classes, adjusts the adaptation calculated for a predetermined class, and specifies the class corresponding to the word extracted based on the adaptation for each class. The specified class name is added as a tag, thereby creating a document 212 to be inspected after processing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
