Embodiment 1

[0050] Such as figure 1 Shown, the Chinese of the present embodiment containing polyphonic character converts the Chinese pinyin method, comprises the following steps:

[0051] Step 110, store polyphonic characters and their pinyin in the first lexicon, store phrases with polyphonic characters and their pinyin in the second lexicon, and store common Chinese characters and pinyin of non-polyphonic characters in the third lexicon.

[0052] Since polyphonic characters have multiple pronunciations, polyphonic characters and pinyin in the first lexicon have a one-to-many structure. And the pronunciation of polyphonic characters in phrases (comprising words, idioms, slang and commonly used expressions, etc.) is generally fixed, so polyphonic characters and pinyin in the second lexicon are one-to-one structures. And the first lexicon also includes the pinyin weights of the different pronunciations of each polyphonic character. The initial pinyin weights can be preset according to th...

Embodiment 2

[0087] In the present embodiment, the Chinese conversion Chinese pinyin system that contains polyphonic characters comprises: data storage unit 1, word segmentation unit 2, first judging unit 3, second judging unit 4, the 3rd judging unit 5, the first translation unit 6, the 3rd judging unit Two translation unit 7 and result output unit 8 . Wherein, the data storage unit includes a first lexicon, a second lexicon and a third lexicon, the first lexicon stores polyphonic characters and their pinyin, the second lexicon stores phrases with polyphonic characters and their pinyin, and the second lexicon stores polyphonic characters and their pinyin. What3thesaurus stores non-polyphonic characters and their pinyin.

[0088] When the user needs a translation, enter a string. The word segmentation unit splits the read character string into several word units, specifically, splitting based on the word segmentation method of word meaning. The first judging unit judges whether the numbe...

Abstract

The invention discloses a method and a system for converting Chinese words containing polyphones into pinyin. The method comprises the steps that S10, polyphones and pinyin thereof are stored in a first word bank, word groups containing polyphones and pinyin of the word groups are stored in a second word bank, and non-polyphones and pinyin thereof are stored in a third word bank; S20, a read string is split into word units; S30, whether the number of Chinese characters of the word units is 1 is judged, if yes, the word units are used as first-class words, and the step S31 is executed, and if not, the word units are used as second-class words, and the step S31' is executed; S31, whether the first-class words are polyphones are judged, and if yes, the first word bank is searched to obtain translation results; S31', whether the second-class words contain polyphones are judged, if yes, the second word bank is searched to obtain translation results, and if not, the step S32 is executed; and S32, the second-class words not containing polyphones are split into first-class words and translated into pinyin, and the pinyin obtained through translation is output after being combined and ordered.

Description

technical field [0001] The invention relates to the field of language translation, in particular to a method and system for converting Chinese into Chinese pinyin containing polyphonic characters. Background technique [0002] Computer users and mobile client users need to enter Chinese in fixed scenarios, and require conversion to the corresponding Chinese pinyin. At present, many systems have realized the automatic translation function of Chinese pinyin comparison, but the translation accuracy of polyphonic characters is not high during the translation process, and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and system for converting Chinese to Pinyin containing polyphonic characters in order to overcome the defects of low accuracy and low efficiency in the way of converting Chinese to Pinyin in the prior art. [0004] The present invention solves the above technical problem...
