Abstract: An information processing apparatus includes a determination, first, second and third receiving, and first and second checking units, and a controller. When a determination result matches a first determination result, the first checking unit outputs a matching determination result as the final output. The second checking unit checks the first determination result against a second. The first and second determination results are respectively received by the first and second receiving units. When the first determination result matches the second, the second checking unit outputs the matching determination result as the final output. When the input information is received, the controller operates the determination, first receiving, and first checking units. When it is determined that the determination result does not match the first determination result, the controller operates selectively one of a unit set and the third receiving unit. The unit set is constituted by the second receiving and checking units.

Abstract: An image processing apparatus includes a common region determination unit, an inherent region extraction unit, and an inherent region connection unit. The common region determination unit determines page common regions which are in common among plural pages of document data. The inherent region extraction unit extracts, as page inherent regions, regions other than the page common regions determined by the common region determination unit from image data in the plural pages. The inherent region connection unit connects plural page inherent regions extracted by the inherent region extraction unit.

Abstract: An information processing apparatus includes: an acquisition unit that acquires, for each past input for a determining unit, a group of sets each including a determination accuracy on an input and correct/incorrect answer information indicating whether a determination result from the determining unit on the input is a correct or incorrect answer; and a determination unit that determines each threshold for defining each section by using the group acquired by the acquisition unit in an order starting from a section where the determination accuracy is relatively high and in such a manner that a correct answer rate of the determining unit obtained from the group of sets that belongs a section satisfies a target correct answer rate of the determining unit corresponding to the section.

The common region determination unit determines page common regions which are in common among plural pages of document data. The inherent region extraction unit extracts, as page inherent regions, regions other than the page common regions determined by the common region determination unit from image data in the plural pages. The inherent region connection unit connects plural page inherent regions extracted by the inherent region extraction unit.

Abstract: An image processing apparatus includes a character recognizing unit that performs character recognition on a first image and on a second image, a comparing unit that compares a first character recognition result of the first image obtained by the character recognizing unit, with a second character recognition result of the second image obtained by the character recognizing unit, a determining unit that extracts matching characters between the two character recognition results, and determines whether a character existing between the matching characters, which is obtained as either the first or second character recognition result, is one of a character deleted from the first image, an inserted character that does not exist in the first image but exists in the second image, and a character by which a character in the first image has been replaced, and an outputting unit that outputs a comparison result obtained by the comparing unit.

Abstract: A document processing apparatus includes a comparison source data acquisition unit that acquires a plurality of comparison source data each including a plurality of comparison source descriptions that are acquired from a comparison source document and ordered; a comparison target acquisition unit that acquires one or more comparison target data respectively acquired from comparison target documents; and a comparison result output unit that outputs a comparison result based on a minimum difference between one datum of the comparison source data and one data of the comparison target data corresponding to one of a plurality of combinations in each of which one of the comparison source data is combined with one of the comparison target data.
