The method and the system for removing the ambiguity of the sliding type pinyin input mode based on the Chinese Pinyin keyboard can be used for sliding-based pinyin inputting in the touch screen equipment. According to the method and the system, disclosed by the invention, the Chinese input performance in intelligent mobile equipment can be obviously increased, the learning cost and the remembering cost of Chinese input are greatly reduced, and an effective path is provided for finally breaking through an information input bottleneck of Chinese information processing of a mobile platform.
