<p><P>PROBLEM TO BE SOLVED: To express the relation between documents classified by categories in an easy-to-understand manner. <P>SOLUTION: The visualization device 10 estimates, based on a document generation model for a document group classified by categories, posterior probability vectors showing the probability of belonging to registered categories, for each document contained in the document group, and the probability of not belonging to the registered categories by vectors. The visualization device 10 arranges, according to each probability shown by the estimated posterior probability vectors, the relation of each document with each category on a visualized space. The visualization device 10 further transmits the visualized space with the arrangement to a user terminal 30. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
