PROBLEM TO BE SOLVED: To automatically detect and correct a misused character and a lacking character in a Chinese document. SOLUTION: A character-to-reading conversion part 200 converts an inputted source document into a reading symbol string. A candidate word detection part 300 cuts a syllable out of the reading symbol string and uses it as a retrieval key to detect possible candidate words and relative information. A similar candidate word detection part 400 uses a reading symbol string after similar bits are masked by a mask means as a retrieval key to detect possible candidate words and relative information. An optimum candidate character string determination part 500 concatenates the respective candidate words by using the start and end position of each candidate word corresponding to the source document as retrieval keys to generate a directional net and takes an optimum path out by dynamic programming by regarding the cumulative maximum value of use frequency plus word length weight plus source document similarity weight plus meaning similarity weight. A matching part 600 matches the character string of the optimum path with the source document to detect and mark dissembling characters. |
