<P>PROBLEM TO BE SOLVED: To provide a document structuring device allowing reduction of cost spent for production of an extraction rule or a document structure-extracting logic model prepared in each target document, and allowing improvement of structure extraction accuracy by only performing browsing operation of the document. <P>SOLUTION: This document structuring device has: a structure recognition means 102 recognizing a document structure from stored document data 101a, and storing it as document structure information 103a; a distribution means 104 distributing the stored document data to a client terminal 105, acquiring a history of a browsing part of a user, and storing it as browsing history information 106a; and a correlation calculation means 107 calculating correlation between document structure blocks from the document structure information and the browsing history information 106a. The structure recognition means 102 receives the correlation between the document structure blocks calculated by the correlation calculation means 107, and re-recognizes the document structure. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
