The Research And Design Of An Intelligent Chinese Digital Input Method

This paper applies a kind of intelligent technology to the CDIM (Chinese Digital Input Method) in order to improve its performance and efficiency. This technology optimizes the input rules of CDIM by adding the separating characters to the input stream. Integrating the intelligent technology and separating input stream into the CDIM, this intelligent Chinese digital input method not only can reduce the average code length, but also can improve the hit probability of first character.First, this paper discusses how to improve the input rule without modifying me original coding rules. Second, it discusses how to design the word-code files, which used to adapt to some different ways of inputting stream. The design of index files also has been analyzed in this part. Subsequently it designs a dynamic self-study language model by unifying the general-purposed language model and the special-user language model. The data smoothing algorithm which is used in these language models of CDIM also has been analyzed in this part. Finally, it designs an illustrated input method which is based on the intelligent CDIM model proposed by this paper. It composes the performance of new input method with the original input system, and then gives some data to analyze the result.
