  • inputting a first and a second structured document each including a plurality of elements and structure information thereof;

    comparing said input first structured document and said second structured document with each other as to elements representing the structure thereof; and

    when a comparison objective element is defined as one for which non-coincidence of occurrence order of the element is not to be taken into consideration, determining the comparison result of said comparing step indicating non-coincidence in the occurrence order as a difference between the structured documents to be excluded from extraction.
