The Continuous Chinese Pinyin Input System Based On Slide Track

With the development of mobile Internet technology and the popularity of mobile terminals,the input method of mobile terminal tend to diversification and intelligence.In recent years,the input method of mobile terminal develop from the original simple press-type physical keyboard to the way of touching,sliding keyboard input which is more natural and fast,but the current mainstream input method of Chinese still remain in the stage of touch keyboard-based input,making Chinese information not efficient enough.Therefore,it's meaningful to apply the technology of touch-screen sliding to pinyin input method which can make Chinese input more efficiently.Based on current situation,the paper mainly proposes a continuous sliding pinyin keyboard input system for mobile terminal.There are three parts of this paper: the design of interactive sliding pinyin keyboard layout,the algorithm of sliding pinyin disambiguation and the design and implementation of continuous pinyin sliding input system.In order to solve the problem that the trajectory path is too long for pinyin sliding input in pinyin keyboard,we have adjust the position of the letter key position to get a new keyboard layout for sliding Chinese pinyin with the study of the pattern of phonetic combination and the position distribution of keys.Compared with the traditional English keyboard layout,it can reduce the memory costs of the keyboard users,and reduce the sliding distance to make Chinese pinyin input more efficiently.Based on the sliding pinyin keyboard proposed,we collect the data of sliding pinyin input to build the corpus for the research of the algorithm of Chinese pinyin sliding track recognition.Then,we proposed two algorithms that one is the pinyin sliding disambiguation algorithm based on deep convolution neural network,and the other one is the rule-based pinyin sliding disambiguation algorithm.The accuracy of the algorithm based on the depth convolution neural network is about 10% higher than rule-based pinyin sliding disambiguation algorithm with experiments.Finally,based on the research of interactive layout design and sliding pinyin disambiguation algorithm,we implement the continuous pinyin sliding input system in the practical mobile terminal application.The system mainly includes interactive design,the Chinese pinyin track recognition module,the word conversion module and the word suggestion module.
