Provided is an information processing apparatus that extracts a character string to be a candidate of an item value corresponding to a predetermined item, from among multiple character strings included in a document image to be processed. The information processing apparatus first obtains information indicating a conceptual feature group of a preset extraction target, then identifies a conceptual feature group to which each of the character strings included in the document image to be processed belongs from among predetermined multiple conceptual feature groups based on a feature vector corresponding to each character string, and then extracts the character string whose identified conceptual feature group is the same as the conceptual feature group associated with the same attribute information as the conceptual feature group of the extraction target, from among the character strings included in the document image, as the candidate.

Information processing apparatus, information processing method, storage medium, and learning apparatus

Processing of an image obtained by scanning an original document and on which character recognition processing is executed on text blocks which are extracted from the scanned image. The text blocks indicate regions of character attributes which may have different data attributes. An estimate is made of the likelihood that a text block is associated with a predetermined data attribute, and a display is made of the scanned image and the character string included in the estimated text block. If the displayed character string is modified by a user, reference information is updated based on the modified character string and history information pertaining to the modification is displayed. The updated reference information is used to improve the estimate of the likelihood that the text block is associated with the predetermined data attribute.

A distance image acquisition unit captures a low-resolution image of an object placed on a document board, and an object detection unit corrects the low-resolution image and generates a low-resolution corrected image. A camera image acquisition unit captures a high-resolution image of the object placed on the document board, and an image processing unit corrects the high-resolution image and generates a high-resolution corrected image. A display unit displays the low-resolution corrected image until the high-resolution corrected image is generated, and displays the high-resolution corrected image when the high-resolution corrected image is generated.

A region division portion extracts an 'object', an 'anchor expression accompanying the object' and a &#x201c;text including the anchor expression&#x201d; from image data based on a paper document and an electronic document. A link processing portion generates link information that associates, in two ways, the &#x201c;object&#x201d;, the &#x201c;anchor expression included in the text&#x201d; or the &#x201c;text including the anchor expression&#x201d; with each other. Then, a format conversion portion converts the link information into electronic document data including two-way link information. When this electronic document data is displayed by an application and one of the &#x201c;object&#x201d; and the &#x201c;anchor expression included in the text&#x201d; is selected, the other can be displayed according to the link information.
