Abstract:
1. A document management apparatus comprising: an acquisition unit adapted to acquire first block information of blocks segmented for each page of document data of a first version, which is obtained by executing block segmentation processing for each page of document data of the first version, and adapted to acquire second block information of blocks segmented for each page of document data of a second version, which is obtained by executing block segmentation processing for each page of document data of the second version; a discrimination unit adapted to discriminate a matched block and a mismatched block between the blocks segmented for each page of document data of the first version and the blocks segmented for each page of document data of the second version on the basis of the first and second block information acquired by said acquisition unit; an extraction unit adapted to extract a block that is determined as a matched block and exists in a page containing a block determined as a mismatched block in the document data of the first version and a block that is determined as a mismatched block in the document data of the second version; a generation unit adapted to generate a page by laying out the blocks extracted by said extraction unit while maintaining a block sequence in the whole document data of the second version; and an output unit adapted to output the page generated by said generation unit.
