Problems solved by technology
Due to the unique characteristics of the mobile platform, which is small in space and needs to be held by the user, it is difficult to perform fast simultaneous input with both hands on a large keyboard like the input method of the PC platform.
At the same time, some use unfixed variable keyboard input, which brings discomfort to users who have been accustomed to the traditional keyboard layout, inconvenient operation, and easy to cause input errors.

Embodiment 1
[0070] Combine below Figure 1 to Figure 5 , take the input process of shang as an example to illustrate.
[0071] Please also see Figure 1 to Figure 5 , firstly, when the user inputs s, the next possible input button will become a larger variable, and the thickness of the line indicates the probability of the next button appearing. Then the user can press h very naturally; then press a, please note that the further a pinyin is entered, the fewer options are available, and the less likely it is to press a mistake. After pressing n again, the only prompt appears; finally press g, the system will automatically determine that the user has entered a complete pinyin, so there is no further prediction, and the keyboard returns to its original state, waiting for the user's next input.
[0072] The prediction of the keyboard in the present invention is based on a single pinyin, that is, the prediction is only for one character, and when the input of a character is finished, the syste...
Embodiment 2
[0074] For example, the user directly inputs i: such as Figure 6 As shown, since there is no combination starting with i in the pinyin rules, the keyboard prediction is empty.
[0075] But if the user enters shani, such as Figure 7 As shown, the system will continue to predict according to ni, so there will be a next prediction.
[0076] In summary, the keyboard prediction method of the present invention can ensure that no matter what pinyin the user inputs, it can accurately predict the next possible letter, and can stop correctly, so that too many predictions will not cause trouble to the user.
[0077] The above is only a preferred implementation example of the present invention, and is not intended to limit the present invention in any form, any content that does not deviate from the technical solution of the present invention, any simple modification made to the above implementation examples according to the technical essence of the present inve...

Abstract
The invention relates to an intelligent mobile platform Pinyin (phonetic transcriptions of Chinese characters) input method based on a language models. The Pinyin input method comprises the following steps of: firstly, training a Pinyin text to obtain a language model based on letters and a language model based on Pinyin; secondly, decoding an input Pinyin string by using an HMM (Hidden Markov Model) decoding method; and thirdly, predicting a next input step and giving out an input promotion: firstly, carrying out prediction according to the language model based on the letters, and acquiring all reasonably-input letters which can occur behind a single Pinyin letter and the occurring probabilities of the reasonably-input letters; then, carrying out the prediction according to the language model based on the Pinyin, and acquiring all reasonably-input letters which can occur behind all possible Pinyin prefixes and the occurring probabilities of the reasonably-input letters; and finally, acquiring all next possible reasonably-input letters and the occurring probabilities of the possible reasonably-input letters by comprehensively considering information of the last two steps, comparing the probabilities, realizing the input prediction according to comparing results, and carrying out the input promotion. According to the intelligent mobile platform Pinyin input method based on the language models, the accuracy rate and the fluency of the input of a user are improved, and the input efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of intelligent information processing, in particular to a language model-based pinyin input method for an intelligent mobile platform that is applied to a mobile platform to make input more humanized and accurate. Background technique [0002] Whether Chinese characters can be input into a computer and whether a computer can output Chinese characters was once a matter of great concern to people. Human society has entered the information society, and one of the most important features of the information society is the use of modern technologies and equipment such as electronic computers to process language and text information, such as storage, classification, statistics, retrieval, conversion, transmission, Control, etc., so that it can be fully utilized and maximize its effectiveness. If Chinese characters cannot be entered into computers, and Chinese character information cannot be processed by computers,...
