A documentation determination device comprising: a recognition unit; and a control unit, wherein an application document and attached documents are input data to the documentation determination device, wherein in the application document, a list of the attached documents is provided, wherein each listed item in the list of the attached documents includes first bibliographic information of an attached document, wherein when the application document, one or more of the attached documents linked to the application document, or both the application document and one or more of the attached documents linked to the application document are image data, the recognition unit is configured to recognize character information from the image data, wherein the control unit is configured to (i) acquire the first bibliographic information for each listed item in the application document, (ii) acquire second bibliographic information of an attached document given in each of the attached documents, (iii) determine a level of agreement between the second bibliographic information of each of the attached documents and the first bibliographic information of a corresponding listed item in the list of attached documents, wherein bibliographic information made up of bibliographic elements such as version numbers and dates are compared, and (iv) report, for each of the attached documents, (a) the second bibliographic information, (b) the first bibliographic information of the corresponding listed item, and (c) the level of agreement between the second bibliographic information and the first bibliographic information of the corresponding listed item, wherein when a second character string of the second bibliographic information of one of the attached documents and a first character string of the first bibliographic information of a corresponding listed item in the list of attached documents do not match, the control unit is configured to (i) generate a pair of images through rendering, one image rendered from at least one non-matching character in the first character string and another image rendered from at least one non-matching character in the second character string, and (ii) compare the pair of images to determine a level of agreement between the pair of images. a recognition unit;

(i) generate a pair of images through rendering, one image rendered from at least one non-matching character in the first character string and another image rendered from at least one non-matching character in the second character string, and (ii) compare the pair of images to determine a level of agreement between the pair of images.
