Abstract: We previously proposed an Efficient Phoneme-based Chinese Input Method (EPCIM) which yields a conflict-code rate of 13.5%. To reduce further the conflict-code rate in inputting Chinese text, an EPCIM-based method that uses a Chinese dictionary from "Hsin-Ku-Yin" input method is developed in this research. Because of the EPCIM’s low conflict-code rate, the large "Hsin-Ku-Yin" Chinese dictionary can be transformed into a very compact EPCIM dictionary which can extend the EPCIM to the Efficient Phoneme-based Chinese Text Input Method (EPCTIM). The EPCTIM uses dynamic programming to resolve ambiguity in the EPCIM code string of a piece of Chinese text and to determine the optimal Chinese word string. Experiments demonstrate that the EPCTIM is very promising because of its low conflict-code rate of 2.67% and its low error rate of 0.32%.
