<P>PROBLEM TO BE SOLVED: To contribute to improvement for easy reading and grasping of respective character strings along a time axis. <P>SOLUTION: This document processor 1 is provided with a receipt part 100, a character string extraction part 110, a similarity calculation part 130, an importance calculation part 140, and an important character string specification part 150. For each character string, the similarity calculation part 130 calculates a degree of similarity of one character string extracted by the character string extraction part 110 with another character string as a degree of similarity. The importance calculation part 140 calculates importance of one character string based on the degree of similarity between one character string and a predetermined number of character strings temporally before/after the character string. Then, the important character string specification part 150 specifies a character string matching the importance when the importance calculated by the importance calculation part 140 exceeds a threshold value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
