<p><P>PROBLEM TO BE SOLVED: To automatically extract a calibration rule in calibration performed to a document from a pre-calibration document and a post-calibration document. <P>SOLUTION: A document reading part 15 reads a pre-calibration document 7 and a post-calibration document 8, and a document analysis part 16 analyses and divides them into elements, and extracts the co-occurrence relation of each element. A frequency calculation part 17 calculates the frequency of the appearance of the co-occurrence relation in the pre-calibration document and the frequency of the appearance of the co-occurrence relation in the post-calibration document. Furthermore, a difference calculation part 19 calculates a difference by subtracting the pre-calibration co-occurrence frequency from the post-calibration co-occurrence frequency, and generates a difference vector with an element included in the co-occurrence relation as a dimensional axis and a difference as a component. Also, a calibration rule creation part 20 inverts the difference vector about the element from which the difference vector has been generated, and when the inverted vector and the difference vector of the other element are coincident or approximate with each other, the calibration rule creation part 20 creates a calibration rule from the element and the other element. Then, a display processing part 21 and a dictionary registration part 22 output the calibration rule. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
