<p><P>PROBLEM TO BE SOLVED: To provide an image processing device capable of generating a feature character string reflecting a content of a document. <P>SOLUTION: An appearance frequency order candidate extraction section 32 extracts candidates of a constitution character string for constituting the feature character string based on an order of appearance frequencies in a document of character strings extracted by a character string extraction section 310. An arrangement order candidate extraction section 34 extracts candidates of the constitution character string for constituting the feature character string based on an arrangement of the character strings in the document extracted by the character string extraction section 310. A feature character string extraction section 36 selects, based on character string order information from the appearance frequency order candidate extraction section 32 and arrangement order information from the arrangement order candidate extraction section 34, two or more character strings from the candidates of the character string included in at least one of the character string order information and the arrangement order information and connects them together to generate the feature character string. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
