Description
Technical field
The present invention relates to a kind of input method, more particularly to a kind of Tibetan language intelligent input method based on phonetic.
Background technology
Tibetan language since initiative, no matter the main carriers as national culture succession, or be used as Tibetan area propagation section now
The main tool of skill knowledge, or even the main indications national as one in informationized society, its unique human culture valency
Value and vast Tibetan area play great function be immeasurable.
Tibetan language strides into recent decades information age, and considerable hair has been obtained in each side of computer Tibetan information processing
Exhibition, also achieves many achievements, Tibetan language typesetting processing, the transmitting-receiving of Tibetan language Email, Tibetan language is entered into from the typewriting of Tibetan language
Web Hosting, the exploitation of Tibetan language application software, the making of Tibetan language courseware etc..
Tibetan language is alphabetic writing, with laterally writing property structure simultaneously also have longitudinal direction write property structure, its phrase or
Sentence is by syllable one by one（Or it is word）Composition, the corresponding sound of a syllable a, syllable has several Tibetan language again
Letter composition, slightly seem that it and English are much like, such asBut for a Tibetan language syllable, it is again from one
Base word starts, and is formed by upper word adding, down word adding, pre-script, back word adding stack combinations, thus has the characteristics of plane word again.Hide
The structure of the syllable of text is using a letter as core, and the letter of core is front and rear on this basis " base word ", remaining letter
Additional and upper and lower fold is write, and is combined into a complete word table structure, and the appellation of each letter is according to the position for being added in base word
And gain the name.As shown in Figure 1.
30 consonants of Tibetan language can make base word, and still, can do forward and backward, upper and lower plus word letter is all in the syntax
As defined in having, and limited amount.
Centered on Tibetan language pronunciation is also base word consonant, a syllable only has a vowel（Vowel a can be omitted）, therefore one
The corresponding sound of individual syllable, when Tibetan language combines into syllables, since leftmost consonant, its order is 1）Pre-script, 2）It is upper to add
Word, 3）Base word, 4）Down word adding, 5）Vowel, 6）Back word adding, 7）Back word adding again.
The writing of Tibetan language is in units of syllable, is from left to right write across the page, and is separated between syllable with dot, such as The sequential write of syllable and the sequence consensus combined into syllables, most of input method are also to come according to this order
Input Tibetan code, but specific input hypothesis are complex, and have the drawbacks of very big because when writing upper word adding or under
Some special letters during word are added to need to deform, so Tibetan language defines 211 characters altogether in international code Unicode, its
In comprising general character, overlaying character, numerical chracter, astronomy and calendrical calculation symbol etc..Opentype character library marker characteristics are recycled, will
These general characters combine with overlaying character, and this function is that fontlib possesses in itself rather than input method, and input method is by root
Character code is formed according to the input of user, fontlib passes through character library marker characteristic so as to show Tibetan language syllable according to this coding.
At present, the input speed of Tibetan language still has obvious gap compared with the input speed of the other parts language such as Chinese,
Especially on mobile terminals, main cause lacks the input method of efficient intelligence.Among existing input method, only a small number of tools
There is the external Tibetan input method such as phrase inputting function, Microsoft's Himalaya input methods not support phrase or intelligent input method, and
Domestic class's intelligence with phrase inputting employs the phrase encoding scheme that base word adds back word adding up to input method, but has not certainly
So, difficult note is difficult uses and repeated code is more, and user can arbitrarily input character any combination, the shortcomings of violating the syntax of Tibetan language.Therefore it is badly in need of
A kind of easy-to-use, natural, versatile and low repeated code intelligent input scheme is developed, to improve the input speed of Tibetan language.
The content of the invention
In order to overcome technical problem present in prior art, searched for it is an object of the invention to provide one kind based on phonetic
Tibetan input method, according to the text structure, pronunciation character and spelling methods of Tibetan language, the present invention is using some letters as phonetic word
Accord with and to identify specific syllable, do not consider that the additive process of syllable represents, realize Pinyin Input, therefore phonetic proposed by the present invention is defeated
It is exactly based on it to enter method.The spelling rule of Tibetan language is specially made good use of, the phonetic of Tibetan language syllable and corresponding relation is deposited
It is put into character library, Pinyin coding is formed by input method, target word collection is returned further according to input method engine.
Therefore the present invention has repeated code low, it is easy to accomplish, the features such as being easy to establish and expand dictionary, and meet Tibetan language writing
Natural thinking, it is readily appreciated that and use.
The object of the invention is achieved by the following technical programs：
A kind of Tibetan language intelligent input method based on phonetic, its step are：
1）Each Tibetan language consonant and each Tibetan language vowel are set into a key mapping code respectively；
2）Pinyin coding corresponding to setting one to each syllable according to the spelling of Tibetan language syllable order, and it is saved into one
In input method character library；
3）Establish the relational tree of a Pinyin coding and key mapping code；
4）One input method engine is established based on the input method character library, the input method engine is according to the key mapping code time of input
The relational tree is gone through, obtains corresponding Pinyin coding；Then the input method character library is inquired about according to the Pinyin coding, returned corresponding
Tibetan language.
Further, the method to phonetic corresponding to each syllable setting one is：For monocase Tibetan language syllable, if
Put its phonetic for monocase Tibetan language syllable in itself；For more character Tibetan language syllables without upper and lower superposition, it is multiword to set its phonetic
Accord with Tibetan language syllable in itself；For there is the more character Tibetan language syllables being superimposed up and down, set its phonetic for monocase Tibetan language syllable in itself.
Further, same Pinyin coding corresponds to one or more syllables.
Further, the input method engine searches the phonetic of matching according to Pinyin coding, by all and this phonetic
Match somebody with somebody or the Tibetan language using this phonetic as beginning is shown in the candidate word region of input method, and sorted by word frequency order.
Further, on the mobile apparatus using full keyboard pattern or nine grids pattern as Tibetan language consonant and member
The inputting interface of sound letter.
Further, the key mapping mode of Himalaya input method is used on PC as Tibetan language consonant and vowel
Inputting interface.
A kind of Tibetan language intelligent input method flow chart based on phonetic of the present invention is as shown in Fig. 2 it is comprised the following steps that：
First, 30 Tibetan language consonants and 4 vowels are provided to form pinyin character, and it is suitable according to Tibetan language spelling
Sequence combines to form phonetic corresponding to every syllable.
Such as the consonant that table 1 is Tibetan language：
Table 1 is Tibetan language consonant table
Such as the vowel that table 2 is Tibetan language：
Table 2 is Tibetan language vowel table
The phonetic according to corresponding to the spelling of Tibetan language order provides each syllable, its is specific as follows：
1. the phonetic of monocase syllable is itself.Such as table 3：
Table 3 is monocase syllable
2. the syllable of character more than has no superposition up and down（Except vowel character is superimposed）When phonetic be itself.Such as table 4：
Table 4 is without the more character syllables being superimposed up and down
Phonetic is determined by the spelling order of the word when 3. syllable of character more than has superposition.Such as table 5 below：
Table 5 is to have the more character syllables being superimposed up and down
According to three above-mentioned rules, we can determine that each syllable corresponds to phonetic, while it has also been found that same spelling substantially
Sound corresponds to multiple syllables.
2nd, create and the phonetic of particular kind of relationship and corresponding syllable are added in character library and character library.
Target syllable is stored in character library with phonetic, and both storage organizations have two kinds of relations from data structure, a kind of
It is one-one relationship, i.e. a string of pinyin characters only represent a syllable, and another kind is many-one relationship, and a string of pinyin representations are more
Individual syllable, due to the particularity of Tibetan language, at most corresponding three syllables of a phonetic.
3rd, input method engine
Input method engine is the core for realizing intelligent input, and it provides an adapter for input method, that is, receives and use
The code value of family input, will find the phonetic code corresponding to the code value in adapter, then phonetic code is scanned for character library, will
The result of search returns to user, so as to complete to input.
Compared with existing input method, beneficial effects of the present invention：
1）It is versatile
Unicode coding of the character coding method of the present invention based on international standard, is easily achieved on different devices.
2）Key mapping typesetting is flexible
Due to the present invention pinyin character quantity it is few, it is only necessary to 34 key mappings, so we completely may be used on PC
In a manner of the key mapping using the current commonplace Himalaya input method used, and it is very ingenious in the terminals such as mobile phone, flat board
Full keyboard pattern or nine grids pattern are realized in ground, and existing mobile phone Tibetan input method does not have nine grids keyboard mode also.
3）The high repeated code of input rate is few
The Pinyin Input based on search is employed, and the many-one relationship amount of phonetic and word is few, not only repeated code is few, Er Qieneng
Preferred word is accurately determined, improves input speed.Such as phraseCommon input method needs 11 keys, and this input method only needs 8
Key, or even less.For shorter word, preferred word can accurately just be determined first by inputting.
4）It is consistent with the writing thinking of Tibetan language, it is eager to learn handy
The present invention is the input method based on phonetic, and Tibetan language is also alphabetic writing in itself, and the writing of phonetic is completely in Tibetan
Text writing thinking coincide, as long as have Tibetan language writing basis can Step By Step understand this input method.
5）It is easy to establish and expand dictionary
Fundamental system character library defined in the present invention, it includes all Tibetan language syllables, and we will be used by being established based on it
Family dictionary, the dictionary not only need good data structure, it is also necessary to good extendibility, compatibility, using the volume of the present invention
Code scheme, can insert all kinds of Tibetan language vocabulary in network in dictionary so that the expansion of dictionary is convenient to be realized.
6）Realize that word frequency records, input is faster
As the Chinese character coding input method of current main-stream, our input method also possesses programming count and the adjustment of word frequency, real
The input mode of user's feature is now adapted to, the memory function of user's phrase can also be realized, makes the input of Tibetan language more convenient, fast
