A modified phoneme-based Chinese input method for minimizing conflict code rate

Previously, we proposed a phoneme-based Chinese input method with conflict code rate 24.7%. In this paper, we aim at constructing a modified method to further reduce the conflict code rate significantly. The modified method first introduces a new feature extraction rule that extracts the feature phonetic symbol of an extended radical in different manners. In the scope of 1043 extended radicals, 10 selected extended radicals are determined to be processed by the new feature extraction rule. The conflict code rate of the modified method is 13.5%, much lower than that of the original method, 24.7%.
