AUTOMATIC DETECTING SYSTEM FOR WRONG CHARACTER OF JAPANESE SENTENCE

摘要

PURPOSE:To greatly improve the overall detecting accuracy of wrong characters and to greatly reduce the overall processing load, by performing concatenately the detection of wrong characters with cut-off of the character concatenation probability and the detection of wrong characters with analysis of morphemes. CONSTITUTION:The character concatenation probability product is calculated with the preceding and next characters of an input character string by means of a character concatenation probability dictionary 8. Then the calculated probability is cut off with the prescribed cut-off value. Thus a wrong character deciding part 22 detects the wrong characters and sends the paragraphs including these wrong characters to a correction processing part 9. While the paragraphs including no wrong character confirmed by the part 22 are processed by a wrong character detecting part 4 through analysis of morphemes. Then the areas including wrong characters are extracted and a position having a low character concatenation probability level is detected at a wrong character position detecting part 7 by means of the dictionary 8 and sent to the part 9. Thus the 1st and 2nd wrong characters can be detected at the part 22 by a series of said processes. Then the 3rd wrong character is detected by both parts 4 and 7.
