PROBLEM TO BE SOLVED: To correct and complement a recognition result which is missed due to erroneous recognition, etc., by referring to an index table, comparing an appearing probability on plural candidate characters in a character recognition result and deciding an order of certainty. SOLUTION: The index table generation part 15 of a processor 14 reads a text inputted from an input part 3, processes the kind of the character which is possibly connected to a prescribed character (string) into a numerical value and generates the index table 8 of a tree structure to be displayed. A knowledge processing part 4 refers to the index table 8 and judges the propriety of a candidate character string being the character recognition result. Information including the appearance probability that the previously selected character appears next to the prescribed character is stored in the index table 8. The knowledge processing part 4 refers to the index table 8 and compares the appearance probability on the plural candidate characters stored in the character recognition result at each character and gives the order to the certainty of the candidate characters. |
