<p>An index-structure specifying device is provided with a segment extracting unit (104) and/or a partial hierarchy extracting unit (105) that acquires a predetermined document form to specify a relational structure of slides from a characteristic document form of an object contained in the slide of a presentation document comprised of a plurality of the slides containing an object such as a textbox, searches for a slid consistent with a predetermined document form in predetermined order from a partial set comprised of a plurality of continuous slides contained in a presentation document, so as to extract a relatively relational structure between slides of the partial set; and an extracted information coupling unit (106) that adds a hierarchy determined by the relatively relational structure between the slides of the partial set to a hierarchy in a presentation document in a slide that becomes the standard of the partial set so as to determine a hierarchy of each slide comprised of the presentation document.</p> |
