Pinyin-to-character conversion method and pinyin-to-character conversion system

Abstract

The embodiment of the invention provides a pinyin-to-character conversion method and a pinyin-to-character conversion system. The method comprises the following steps of: a step of generating a sentence, i.e. according to a pinyin segmentation path weight calculating rule, sorting all pinyin segmentation paths of a pinyin stream which takes a current character as an ending and selecting a first preset number of pinyin segmentation paths with the highest weight values in all the pinyin segmentation paths to carry out sentence generation; a step of carrying out Unigram word formation, i.e. carrying out Unigram word formation on all the pinyin segmentation paths of the pinyin stream which takes the current character as the ending; and a step of carrying out processing, i.e. carrying out duplicate removal and sorting on a sentence generation result and a Unigram word formation result to obtain a pinyin-to-character conversion result of the pinyin stream which takes the current character as the ending. By the method and the system which are provided by the embodiment, the pinyin-to-character conversion is implemented; and the sentence generating efficiency is improved by sorting possible sentence or phrases or Chinese character candidates according to a certain sequence after carrying out duplicate removal.

Description

technical field [0001] The invention relates to an input method, in particular to a phonetic-character conversion method and system used in the input method. Background technique [0002] In recent years, mobile communications and the Internet have become the two industries with the greatest market potential, the fastest development and the broadest prospects in the world today. At the beginning of this century, the total number of global mobile users was only about 720 million, and the number of Internet users was about 360 million. By 2010, the number of global mobile users exceeded 5 billion; international Internet users exceeded 2 billion. The total number of mobile users in my country has also exceeded 500 million this year, and Internet users are close to 400 million. With the rapid development of these two industries and technological progress, more and more people hope to access the Internet at high speed to query and obtain information and complete work while movi...

Problems solved by technology

Individual input methods allow users to customize Shuangpin, but user customization is more difficult

[0012] 3. The keys of the full keyboard on mobile platforms such as mobile phones are small, and it is very easy to press the wrong key when performing continuous pinyin input, which affects the efficiency of entire sentence input

Most input methods do not provide the function of automatic error correction for continuous input of pinyin

[0013] 4. Many users have inaccurate pronunciation (such as z|zh), and most input methods fail to provide support for fuzzy sound input
