Abstract
A system and method for detecting and correcting mismatched Chinese characters in a phrase. The system comprises a database for the look-up of characters and Chinese phrases, a module to compare the input phrases with the look-up data retrieved from the database and a module to correct the mismatched characters. The database contains correct phrases as well as attributes associated with each character, such as pronunciation and radical composition. The modules inputs a Chinese phrase that has at least two characters and compares it with the data retrieved from the database to determine if there are incorrect characters. The spell checking method includes two groups of steps: mismatched character detection and mismatched character correction. Whether there is any mismatched character to be corrected is determined by the edit distance, the phrase length and comparisons of the pronunciation and radical composition of the mismatched characters.
